苏州潭山硫铁矿在面临亏损、濒临倒闭的情况下,邀请煤炭科学研究总院唐山分院矿山测量研究所协助解决了主井保安矿柱回采问题。主井场地有两个断层组,其一大断层距井口中心6m,地质条件复杂。科研人员在周密调查的基础上,认为采动影响下断层的滑动会产生较大的非连续性破坏,但也能吸收和消弱附加应力,起到屏障和保护位于断层下盘上的主井的作用。在定性分析的同时,提出了用不同的断层移动影响系数定量计算主井场地上各区段的移动
In the face of loss and dying collapse, the TanShan pyrite mine in Suzhou invites the Institute of Mine Surveying, Tangshan Branch of the Coal Science Research Institute to assist in solving the problem of the recovery of the main pillar of security pillars. There are two fault groups in the main well site, one of the major faults is 6m away from the center of the wellhead and the geological conditions are complex. On the basis of careful investigation, researchers believe that the slip caused by the mining-induced faults will have greater discontinuity damage, but also absorb and weaken the additional stress, act as a barrier and protect the main shaft Role. At the same time of qualitative analysis, it is proposed to quantitatively calculate the movement of each section on the main well site by using different influence factors of fault movement
