The Research In Large Tilt Angle Coal Seam Mining Of Its Plank Moving And Controlling

The acclivitous coal seam adopts tilt to one side along the wall mines, its tunnel arranges the system, well ventilated system with transport the system simple, have the tunnel digs into the rate low, raw coal recovery the rate is high, producing the ability big, the economic performance shows advantage, suffering the extensive valuing abroad with applied. Along with the horny aggrandizement in coal seam, the regulation of the work a plank activity compared with inclined circumstance to take place the homologous variety, if the set uses the inclined mineral mountain pressure in current that coal seam mine presents the regulation manage a plank, will produce many techniques problem, from but the influence produce with the safety. When the inclined work in mines the angle the larger than 12° , exsit a plank hard management, work conveyance difficulty enlargement, the worker labors a series of problem in etc. in enlargement in strength.How to resolve these problems is prior condition that the key that the big in expansion Cape is inclined to mine, but the big Cape is inclined to mine the then big in a research for the plank moves the characteristic Capethe inclined mining.This thesis joins together Zhangzhuang coal mine ,2315 work masks have of the adopts the angle 24° , "three soft" coal seam, firecrackerses adopt, the single body fluid presses a regulation for pillar etc. Is actual, toing tilt to one side longly the wall adopts the coal method a plank move as the theoriesfoundation, method that adoption calculator number imitate, analyze a plank pressure and ambulatory regulation, the point research should work the is inclined to mine a knothole characteristic, putting forward a plank control design with aim at the sexual management measure.This study result is applied in work of 2315. Capes are inclined to mine in the fulfillment, realizes the work safety produce with high produce efficiently, the result shows good.
