摘要
为了探究钱营孜煤矿工业广场立井井筒与地表同步沉降的原因,根据GB 50384—2007《煤矿立井井筒及硐室设计规范》,对钱营孜煤矿主副井罐道间隙实测值进行的统计分析,详细对比说明了主副井罐道间隙的压缩现象以及其发展变化规律。
For explore the reason of synchronous subsidence of surface and industry square shaft of Qianyingzi Coal Mine,according to GB50384-2007 Code for Design of Coal Mine Shaft and Chamber,and combining of statistical analysis of Qianyingzi Coal Mine shaft guide clearance,we comparably illustrate the compression phenomenon of main and auxiliary tank clearance and its developing trend in detail.
