摘要
为了优化老虎台井田工作面布置并制定相应的防治水技术措施,以计算机数值模拟为手段,从煤田特殊的煤岩层-断层空间关系出发,深入研究了工作面重复采动情况下上覆岩层中产生的位移特征、断层面两盘岩层位移特征和离层发育位置及高度等特征,从而科学地揭示了离层裂隙在煤层重复开采时的发育特征。
In order to optimize the work-face arrangement as well as formulate water control technical measures, the mine field special space relations were firstly analyzed. Then, the displacement characteristics in the overburden strata above the coal seam during repeat mining, displacement characteristics in the overburden strata near the two fault walls, and location, height characteristics of abscission layer fracture were further studied with computer numerical simulation. At last, the disturbance law of the abscission layer fracture was scientifically revealed.
