Abstract
In order to solve the problem of heaping waste in aboveground,a technique of disposal waste in underground was proposed.Applying theory of mining subsidence and by means of the maximum height of residual space of the compacted filling-waste within the limits of mining subsidence,the layout of waste filling roadway was determined.Based on numerical simulation method to analyze stress distribution of coal-pillar of both sides of filling roadway and to remove 'mutual influence of multi hole' caused by driving filling roadway,the driving sequence was optimized and determined.The filling process of waste was designed.The technique has been successfully used in Xingdong Coal Mine and the good results of disposing waste in underground and mining coal resource under the surface building have been realized.
