Strip pillar mining method under village structures in Tieshenggou coal mine

Abstract：Based on the specific geological and mining conditions and surface structures status in Tieshenggou coal mine, Henan province, China, the strip pillar mining method under village structures was analyzed through theoretical calculation and prediction of surface movement and deformation.Then, the strip pillar mining plans and their parameters were presented.The results demonstrate that it is feasible in technique and reasonable in economy to extract the coal reserves under village structures by using strip pillar mining method in this coal mine, and coal mining in safety without moving village structures can be carried out.It is significant to increasing recovery ratio, solving the conflict of mining and panel development by using the method.
