摘要
在对尖岩河井田采空区进行资料收集处理的基础上,结合地表塌陷调查,并依据地表和采空区实际情况,运用FLAC 3D计算得到采空区沉降结果,研究显示断层会对地表变形造成较大影响,尤其当断层与采空区有交叉覆盖时,会加大采空区带来的岩层变形,导致比较大的地表沉降。
On the basis of data collection and processing of the goaf in the Jianyanhe well field,combined with the investigation of surface subsidence,according to the actual situation of the surface and goaf,the settlement results of the goaf are calculated by FLAC 3D,and the fault will have a great impact on the surface deformation,especially when the fault and the goaf are cross-covered,the rock deformation brought by the goaf will be increased,resulting in a relatively large surface settlement.
