English Abstract

There is an important significance to develop a set of short-wall mechanized mining technologies, which are adapted to the coal mining under buildings, water bodies and railways and the coal mining of boundary coal seam in our modern mine area. Three kinds of roadway layouts of short-wall mining were brought forward and the mining technique and forming a set of equipment of short-wall mining were studied according to the home-made equipment of short-wall mining and the situation on protecting earth's surface by pillar remaining in mining under buildings, water bodies and railways. The stability of coal pillar of the short-wall mining was analyzed systemically by numerical simulation with the rock failure process analysis software (RFPA2D). The result was applied to the practice of short-wall mining under villages of Wuyang mine to achieve the safe and high-efficient exploitation and control the mining subsidence effectively.
