Mining of coal mine gob filling and packing process along the left lane empty

A suitable process for filling coal mining, the process is broken and the mining area filler mixing station chamber is arranged in the top of the hill track, roadway filling arranged at a distance the working surface mining overburden, the goaf Bored through the tunnel over the filling sector gob is filled in the filling pipe laying the roadway, and the sealing action between the coal face mining face the goaf hydraulic rear cover plate bracket and goaf separated Gob filling technology with a hydraulic prop and the steel template and filling Gob separated to gob. By filling the filler material into the conveying line goaf; after solidification of the filler material have a certain strength, for advancing work before mining, mining and filling cycle. Advantageous effects of the present invention is that: the effective control of Ground pressure reducing subsidence; gangue avoid occupying farmland, eliminate environmental pollution caused by waste dump, green coal mining can be achieved.
