Multistorey Building in Mina Jamarat




THE MINA JAMARAT

Introduction
The stampede in Mina not far Mecca, took place on Zulhijjah 10 1424 H or Sunday February 2 2004 AD, remain in the heart of many Muslims the world over who lost their love one in the unexpected accident. It later came to light, that Jamarat, the place where pilgrim (hujjaj) carry out the rite to cast pebbles into three pillars, known as: Ula, Wustha, and ‘Aqabah, can no longer cope with rising number of Muslim coming from around the world willing to perform Hajj pilgrimage to the Holy Land in Mecca and Medina. Please bear in mind, when Prophet was alive around 600 AD, the earth population was around 200.000.000 people. Now the population of the blue planet is over 7.000.000.000. It seems that the earth is getting smaller with time, and ever becoming smaller in future as science and technology advance.
What many Muslim from around the globe really concern during Hajj pilgrimage to Holy Land, is congregation in Mina on Tasric Days. At that time a multitude pilgrims pour down from Mount Arafat to Mina to execute the rite of pebble casting in an open-air affair Jamarat, after Wuquf (a short stay from noon until dusk on Mount Arafat), followed by collecting adequate number of pebble in Musdalifah, a location on the way to Mina from Mount Arafat.
To get rid of recurring stampede, it is necessary to bring down the density of pilgrim on rites venue, with the introduction: Multi-elevation Pebble Casting Rite, abbreviated MPCR, making each stoning venue on various elevation in the multistory building may be controlled. It is also about the makeover of present Mina Jamarat from: “open-air affair” into “event inside a multistory-building”, so pilgrim can get access to every sites: Ula, Wustha, and ‘Aqabah, from various floor inside the multi-story building, so the density of pilgrim on every venue may be controlled and monitored closely, to get rid repeat of stampede.
A. Number of Building Floor
One aspect of the makeover is to establish a building in Mina, right where the Jamarat is, to multiply number of ritual sites as shown in Figure-I. Figure-Ia shows the multi-floor building seen from the side, without scale.

Figure-I



As can be seen in this proposal, the building is supposed to consist of five floors, including the ground floor. The sites represented by letters: A stand for Ula, B stand for Wustha, and C stand for Aqabah, complete with the respected pillars are visible in the side view. There are sumps underneath each pillar to collect pebbles thrown out by pilgrims gathered by earth’s gravity. With the conversion of Mina Jamarat from open-air affair into inside a multistory building, the number of rites venue will be increased by three as number of the floor grows. The ceiling height in each floor be taken the same. Figure-Ib shows the bird’s-eye view of the multistory Jamarat building. An ellipse chosen to give pilgrims plenty room to wander around. Other bird’s-eye views like square or round are also welcome. The pillars are seen in Figure-Ib.
Figure-II shows a typical Pebble Cast Site, abbreviated PCS, will be available on every floor of the multistory Jamarat building, where pilgrims throw pebbles at its pillar. The pillars will represent sites known as: Ula, Wustha, and ‘Aqabah, to be available on every floor at which pilgrims carry out the ritual of casting pebbles, or small stones. Figure-IIa shows the side view of cross-section of PCS, while Figure-IIb shows its bird's-eye view. Please note that there is a hole at the center of each pole for purpose channeling the thrown pebbles into sump beneath. In an open-air affair Jamarat there are only 3 (three) PCS to cast, but inside the multistory Jamarat building with five floors, there are 15 (fifteen) PCS, rises due to “magic multiplication” of multistory new Jamarat building.




Figure-II



To get pilgrims from ground surface or ground floor to various elevation in the new Jamarat building, or back the other way round, a special designed elevator be used, called: Jamarat Elevator, shorten JE. There are eight JE be propose to move pilgrims from ground floor up to elevation of various heights inside the new Jamarat building, or back the other way round. 
The bird’s-eye view of elevators (JE) to be built around the periphery of the new Jamarat building, are shown in Figure-Ib, indicated by numbers: 1, 2, 3, 4, 5, 6, 7, 8; and equally spaced. Should each floor is served by two elevators, then it follows: JE-1 and JE-5 for the fifth floor, will ascend pilgrims from ground floor to the fifth floor; or back to ground floor the other way round. JE-2 and JE-6 are for the fourth floor, will ascend pilgrims from ground floor to the fourth floor; or back to ground floor the other way round. JE-3 and JE-7 are for the third floor, will ascend pilgrims from ground floor to the third floor; or back to ground floor the other way round. JE-4 and JE-8 are for the second floor, will ascend pilgrims from ground floor to the second floor; or back to ground floor the other way round.
Ground floor will keep the old established custom of pebbles casting on every site. With the advent of elevator (JE), pilgrims will effortlessly get to every altitude in the new Jamarat building from ground floor to carry out religious rites; also effortlessly get back to ground floor the other way round; because every JE is driven by brake induction motor fed from utility. 
With a new building in Mina Jamarat complete with eight JEs from around the building, density of pilgrims on the rite venues of every floor may be controlled and monitored closely in real time on Tasric Days, to get rid of recurrent stampede. 
The propose JE-1 and JE-5 are as in Figure-III use to serve fifth floor, or highest floor of the new Jamarat building. As shown in the picture, it consists of two main parts: saucer (S) and column (K). The saucer also known as Pilgrim Elevator, shorten: PE, built circular like a saucer. It is build to move pilgrims standing from ground floor to the fifth floor in the new Jamarat building; or back to ground floor the other way round. Figure-IIIb is the bird’s-eye view of JE-1 or JE-5, where JE or saucer and its central column are seen. An EDP (Embarking Disembarking Port) is required by the saucer to mediate with each floor in the multistory building, so pilgrims can be easily get into PE or saucer, or leave it the other way round, trouble free.
Having PE or saucer built for pilgrims, number of pilgrim entering or leaving every floor of the new Jamarat building may be controlled and monitored to avoid stampede. The dimension of JE-1 or JE-5 may be estimated the following. If ceiling height of every floor is supposed to be: 10 m, then height of the Central Column, shorten: CC of JT-1 or JT-5 would approximately: 4 x 10 = 40 m. If CC height to diameter ratio is taken: 10 to 1, then the diameter of JT-1 or JT-5 would be: 40 : 10 = 4 m. If the ratio of PE or saucer diameter to CC diameter is supposed: 4.5 to 1, then diameter of the PE or saucer become: 4 x 4.5 = 18 m. Having such a diameter, a PE or saucer will have the capacity to move about 500 pilgrims one way up to fifth floor, or back to ground floor the other way round. 




Figure-III



Figure-IV is the JE-1 or JE-5 be enlarged. Figure-IVa shows the side view where the saucer and its central column seen clearly. The saucer will be equipped with multi-door out of thick glass around the circumference of the saucer, and will be synchronously open or close driven by a mechanical system, and open ceiling. Having multi-door that open and close mechanically, it also become fence to guard pilgrims from falling to ground. An octagonal rotating axle is established to become part of driving mechanism to ascend the saucer up, or descend it back the other way round, lies under the saucer’s floor,  is seen as straight line in the drawing.
Similar multi-door also be built around the circumference of each EDP, face-to-face with the saucer’s multi-door to prevent pilgrim from falling to ground when saucer on the move.  Figure-IVb shows the bird’s-eye view of the saucer along with the central column. The drive mechanism use to ascend the saucer up, or descend it back the other way round, will comprise of: an induction motor, an octagonal rotating axle for mechanical power transfer, and a number Lifting Devise (LD). With this mechanism, will enable the saucer climbs the central column up, or climbs it down the other way round. 
There are eight LD being proposed be installed around the periphery of every central column to move the saucer up, or down the other way round, driven by a brake induction motor. Every LD  is backed by simple technology: 1. Bolt-Nuts with Bevel Gears, or 2. The Rack-Pinions with Bevel Gears and Worm Gears. All LD will in unison move the saucer up, also in unison move it down back the other way round, driven by a brake induction motor. 
Mechanical power comes from a brake induction motor (M) under the saucer floor to move  the saucer (PE), first sent to a torque converter for speed adjustment, and to bevel gears I (white dot), then into polygonal revolving axles. These revolving axles connected with each other by way of bevel gears at their ends (black dots). The polygonal drive system is really an octagonal revolving axle: AB, BC, CD, DE, EF, FG, GH, HA, in horizontal position. From center of every axle (white dots) at points: P, Q, R, S, T, U, V, W, mechanical power be delivered to every LD, each being fixed to C-Channels, or U-Channels. Then LD C-Channel pair, or LD H-Channel pair, being clamped around the circumference of central column, equally spaced. 
The saucer cannot sink by the pull of earth gravity due its weight and pilgrims inside, unless be driven by its brake induction motor. The octagonal revolving axles will synchronize speed of each LD mechanically, will enable all LD in unison climb the central column up, or in unison climb the central column down the other way round. Number of LD to be place around the circumference of central column may vary, much depend on design, dimension, and the lifting force required to move the saucer up or down. 
With the introduction of stepper motor, each LD now get individual drive. Then the mechanical synchronization of all LD to climb the central column up, or climb it down the other way round, must be switched to electrical synchronization, or electronic synchronization, or  digital synchronization.





Figure-IV



The saucer and EDP built out of steel involving: channels, pipes, plates, etc. Also for driving mechanism such as axles, gears, etc. Lighter material can also be used to reduce weight such as: aluminum, carbon fiber, and others. The saucer is equipped with multi-door around its periphery out of thick glass driven by mechanical system to open or close synchronously. The mechanical drive to move the saucer up, or down the other way round, is   under the floor to allow a brake induction motor drives it against  the central column making use eight LD. The central column can also been built out of reinforced concrete on site, or rolled steel or cast steel, right from factory. 
Electricity comes from utility by way power cable to enter the Jamarat panel. Power then be distributed to each JE panel, and by way of a three phase insulated copper rails running along  inner central column to be collected by carbon brushes before being sent to saucer’s panel. In case of power failure, an emergency power supply will immediately take over.
With advent of solar panel and wind generator, energy harnessed from sun and wind can run JE after being converted into electricity.
From saucer’s panel electricity be distributed into a brake induction motor, emergency power charger, lighting, air condition, electronic control, etc. Electric power system be equipped with the necessary switching apparatus, circuit protection, and monitoring. 
A PLC (Programmable Logic Controller) is necessary to interface the saucer operator with its electromechanical drive system, along with electrical wiring, push buttons, control, etc.. 
A monitoring system will help the saucer’s operator monitor event, adjust speed of ascend or descend based on gear ratio put to motor torque converter. A troubleshooting system must be available for the smooth operation during service. 
A trained operator has to run JE professionally. First, he/she presses the OB (Open Button) while the saucer is on the ground floor, then multi-door around the periphery of the saucer and EDP   immediately open. He/she then invites pilgrims to get in from various directions to save time and hinder stampede. As the pilgrim count approaches the proposed number, in this case 500, he/she presses the CB (Close Button) causing saucer and EDP doors to close. He/she then presses the UB (Up Button), and saucer ascends along its central column at a minimum speed of 10 m/minute, or 0.6 km/hour. As the saucer hits its upper limit switch, the brake induction motor stops, and the saucer arrived at its destination. He/she then presses the OB (Open Button), and both multi-door around the saucer and EDP open, and pilgrims leave the saucer. Finish.
At its destination floor, another group of pilgrims may have been waiting. When the saucer is empty, He/she pleases them to get in. As the pilgrim count get to saucer’s capacity, he/she presses CB and multi-door around the saucer and EDP periphery close. He/she presses the DB (Down Button) and the saucer descends along its central column. The saucer moves downward at almost the same speed as it moves upward. As the saucer hits its lower limit switch, the brake induction motor stops, the ground floor has reached. He/she then presses OB, and all multi-door open, and the pilgrims allowed to leave. The saucer is now empty, and it is ready to ascend again, and so on. Finish. 

B. Environmental Concern
Another aspect of this proposal, is about to conserve the environment around Musdalifah from becoming small stone quarries. It is about to establish a Pebble Making Factory (PMF) nearby, so pilgrims only collect MP (Manufactured Pebbles) from a prearranged dispensers strategic  location in Musdalifah, instead collecting NP (Natural Pebbles). One day in the future, pilgrims only cast MP and refrain from exploiting NP so the environment around may be preserved. Already enjoin in the Holy Al-Quran 2: 11, a verse stating: “Make no mischief on the Earth”, with similar verses repeated many times after in the Holy Book.
It is now the time for Muslim scholar to define properties of MP such as: shape, volume, density, hardness, rebound factor, color, and imprint, etc. From the PMF in nearby, MP be carried to Musdalifah, en route from mount Arafat to Mina, is distributed into the pebble dispensers, so the wayfarers and vehicle riders can collect the required amount to Mina during the midnight transit, for casting onto Ula, Wustha, and ‘Aqabah. Thrown MP be gathered by earth’s gravity to the sump underneath every PCS column, be sent back to Musdalifah and fed into MP dispensers. In this way, MP will run a close cycle, and the exploitation of NS from the surrounding will decrease with time, and in long run ceased completely.
With advent MP, no worthless things such: worn out sandals, dilapidated materials, etc., ever be thrown into rite site by naughty pilgrim, making every venue in new Mina Jamarat building always immaculate. Of course some MP may lost in the cycle, or taken by pilgrims to their land for memento, or lost in transport, or other. Lost MP be replenished immediately by PMF. In this way, Muslim of the next generation will get better taught to save and value the natural living environment. If kinfolks in far places across the world might be convinced, even for small stone like pebble one better resort to MP instead of NS to cast. Hopefully one day the message can get across the globe, and “mischief on earth” since the outbreak of industrial revolution may surely come to an end.
