Optimality Analysis of Pillar Dimensions in Room and Pillar Mining

摘要：

In room and pillar mining, pillar width on the one hand plays a vital role on the roadway stability and ground pressure controlling of adjacent stope, on the other hand directly affects the economic performance of enterprises.Theoretical calculations and the UDEC numerical simulation method based on Wangqing Dragon Energy oil shale mining geological conditions is conducted to optimize the reasonable pillar size and conduct analyze its feasibility.It compares the bolt and non - bolt support schemes, ultimately determine reasonable pillar size and guarantee safe and effective mining.
