support, is situated between the synthesis to pick puts goes against between the coal support and the slipping topbeam one kind of transition type support, it by the host, the subframe is posed, the host, the subframe are posed by the topbeam and three hydraulic pressure props, the host, the subsidiary spar fall the slide achievement through one pair to fall an organization, between its and is connected with a pair of expandable joint arm, causes the entire working surface to possess in uses the support all to connect a whole, the entire working surface supporting beam build bees the work shape, front end the king post is loaded with vane type throat Liang, main subsidiary spar rear endAll is loaded with the box writing style “the bow” the shape stabilizing bar, about the pedestrian as well as puts the coal work and so on all on under after stabilizing bar shield, strengthened the stability, the security greatly, moreover has a quite fortable spacious work environment, the support support is highly ~, at the beginning of the design supports the strength is 900kN, the fixed working resistance is 1800kN, controls the zenith distance is most greatly , 10 slightly controls the zenith distance is center distance , the support volume small, the weight is light, the support transportation, the installment, the disassemblage, the replacement, the accent frame, the operation quite are convenient nimbly. 4 Picks puts the craft (1) Coal cutting, transports the working surface use domestic product MG150AW double roll coal mining machine falls the coal, the coal mining machine truncation depth is , the feed way for the reason bevelling feed, mining coal is highly , puts goes against coal thick ~, the coal cutting uses the SGD220 scraper chain conveyor transportation, puts goes against the coal to use the SGW40 scraper chain conveyor transportation. (2) Shop , against the shop metal diamond work, the extends , long , the material is the 10 galvanized wire, mesh for 6060mm, the working uses the 14 galvanized wire, separates the hole double strand to cancel twists 3, the artificial shop working, spreads lag coal mining machine 5~10m, through raises support throat Liang to contract the shop good wire ting to carry on the temporary supports and protections, simultaneously uses the DZ2500 monomer prop in coal wall each 4~5m to hit a belt hat column to go against the area spatially as the coal wall the temporary supports and protections. (3) Moves the pay attention to the prompt supports and protections, after the coal mining machine coal cutting must move promptly the frame, pursues machine moves a distance not to be bigger than 2, moves a speed slowly when should 11 reduce the coal cutting when takes back subframe throat Liang first, raises the subframe three props, first moves subframe , the fluid injection rises the column, the similar subframe operation, first moves main frame , after moves integrity to move again neighboring. (4) Puts goes against the the experiment determined as soon as the working surface puts the coal craft is two picks puts, puts a coal step distance is , uses the monowheel gap to put the coal way from bottom to the low position to put the coal, puts the coal mouth to cut “Ⅰ” Long , the end opening is apart from on the chute along 100mm, puts coal mouth spacing , simultaneously opens puts the coal mouth not to surpass 3, after puts the coal to see the gangue to block immediately, mouth use “” seal. (5) Cycle operation cycle operation way uses 38 systems, two classes produce one class to overhaul. 5 Working surface ores Press the appearance rule through to parameter tests and so on 7177 working surface support working resistance to indicate that, the roof first presses a step distance is 19~29m, in the working surface, middle first presses a step distance basically close, lower part the working surface first presses a st。
