摘要
充填开采首要问题是充填料的运输可靠性。南屯煤矿选择改造风井为充填材料投料井,并对投料系统进行了设计,合理布设投料孔,设计缓冲装置及料石仓,有效解决了充填材料从地表运输至井下的运输问题,对矿井可持续发展、延长矿井服务年限有着重要意义。
The primary problem of flling mining is the transportation reliability of flling material. Nantun coal mine transform air shaft as flling material feeding well, and the feeding system was designed, reasonable layout of the feeding hole, the design of the buffer device and material storage, effectively solve the transportation problem of flling materials from surface to underground transportation. It is of great signifcance to the sustainable development of the mine and the prolongation of the service life of the mine.
