摘要
工业广场保护煤柱是三环公司立井的最后的可采资源,经过论证采用走向条带开采方案。为实现工业广场煤柱安全开采,应用开采沉陷理论方法,进行开采引起地表及构筑物的预测移动和变形的计算分析。据此确定采动影响程度,制定不同设施的维修或调整方案,以保证在煤柱开采期间矿井生产系统的正常运行。
Mine plant coal pillar is the last recoverable coal resources of Three--Circle Company. Based on assessment, the mining method of stripe mining on the strike is used. For a safer recovery, the theory of mining subsidence is applied in the calculation and analysis of the expected movement and deformation of the ground and surface structures. With the mining impact assessed, maintenance or adjustment plans are worked out for different underground structures so as to ensure a normal operation of the entire production system is achieved while the mine plant coal pillar is recovered.
