我矿井下-125水平南北两翼下山采区因生产排水需要,分别在-230m、-215m两处开凿了水泵房、水仓等峒室。但竣工后不久尚未投入使用,便出现了严重变形破坏而被迫翻修。由于两工程所处的区域地质构造形态及变形破坏形式极为相似,笔者为探究其原因,进行了调查和分析,找出了一些本质性、规律性的东西,现叙述如下供参考。 一、工程所处的区域地质构造形态
I-125 level below the mine north-south wings down the mountain mining area due to the production drainage needs, respectively, at -230m, -215m two dug pump room, water tank and other room. However, it was forced to undergo renovations due to severe deformation and destruction which had not been put into use shortly after completion. Due to the extremely similar geological formation patterns and deformation and destruction patterns in the two projects, the author conducted investigations and analyzes to find out the reasons for the problems and found some essential and regular things. The following are for reference. First, the project is located in the regional geological structure
