Study on Modern Mine Harmonious Development Cycle Development
The authors of this article proposed the gateways and rises should be arranged in the same coal seam, that is single-layer layout coal roadway, from the source of production in order to reduce waste is to produce; The establishment of fully mechanized coal face gob filling system and the implementation of with waste rock for coal, filling fully mechanized, and from the mining process it should be achieved simultaneously that waste do not be hoisted out of mine and that it should be filled in the gob to control surface subsidence, the surface subsidence coefficient will be reduced to the minimum; by a large-diameter ground drilling direct to underground, the original ground waste pass through the drilling into the pit bottom, and then transported to the fully mechanized coalface gob waste-filling system, and backfilling ground waste to the gob and eliminate ground Waste Dump, and thus fundamentally solve the Waste Piles of land, and the spontaneous combustion as well as mining subsidence and other problems; Establish coal washing plant, 100% raw coal should be washed, so as to increase own coal sale proceeds; and lower coal terminal users environmental pressure; Build sewage disposal and recycling systems, washing plant emissions of coal slurry, after dehydration and drying, the dried coal slurry into the power plant, and the processed water into washing plant to recycling; The establishment of coal slurry mixed with waste power plant, the use of waste mixed with the coal slurry that after dehydration and drying to combustion power generation; establish the Ordovician limestone underground water divert and use system to solve the problem of mine production safety and the difficulties in production and daily life; Ground subsidence area should be harmonious and comprehensive reclamation and management, so as to recycling mine Ecological Garden.
harmonious development filling fully mechanized ground waste pass through the drilling into the pit bottom energy saving and emission reduction recycling mine ecological garden
