摘　　要：本文针对陕西省咸阳市彬长煤矿井田某盘区开采所引起的地表下沉难以治理的现状,对煤矿开采中新老采空区之间互扰所引起的沉陷盆地变化规律进行研究。综合运用以往地质资料、钻孔柱状图、现场调研、瞬变电磁勘探、岩移观测等多种方法,根据采集数据结合理论经验,构建沉陷盆地数字模型。为煤矿后期因采空区沉陷所引起的地质灾害预警和治理提供了可靠的资料依据,为类似井田在今后的开采提供了宝贵的经验。In view of the current situation that it is difficult to control the surface subsidence caused by the mining of a panel in Binchang coal mine,Xianyang City,Shaanxi Province,this paper analyzes and studies the change law of subsidence basin caused by the mutual interference between new and old goafs in coal mining.Based on the previous geological data,borehole histogram,field investigation,transient electromagnetic exploration,rock movement observation and other methods,the digital model of subsidence basin is constructed according to the collected data and theoretical experience.It provides reliable data basis for early warning and treatment of geological disasters caused by goaf subsidence in the later period of coal mine,and provides valuable experience for similar mine fields in the future.
