METHOD FOR FORMATION OF INTERLAYER FLOOR IN MINING THICK EVERFROZEN COAL SEAMS

摘要

Usage: The invention relates to mining and can be used in underground mining operations at the recess and the layer solves the problem of producing the interlayer overlap of caving of the roof immediate upper layer by filtration preheat vapor through them, thus humidifying obrazuyuschims condensate followed promora- zhivaniem them at the expense of the natural temperature of the rock mass. SUMMARY: in the process of paroobrazovate- L, thermally insulated pipes 2, 3 laid on a well drilled in the air supply drift lava and lava on the roadway to the supplied steam, which enters the goaf by steaming needles 4 associated with the face conveyor 5, and a flexible hose 6, laid on the lava and connected through a valve 7 to a conduit 2. After advancing support frame for width harvester capture process humidification caving of the roof immediate repeated. 2 yl. w fe
