| 摘 要： | 采空区发生透水、地面沉降以及塌陷等问题不仅严重威胁着矿井的生产安全,还威胁地面人们的日常生活,因此探测地下采空区分布是非常必要的.本文建立了几种采空区和采空区塌陷的地质模型,模拟计算采空区和采空区塌陷在地表引起的全张量微重力异常响应,比较分析全张量微重力异常响应特征.模拟结果与理论分析是一致的,可为采空区或采空区塌陷的...

| Abstract: | The problems of water seepage,ground subsidence and collapse in mined-out area not only seriously threaten the mine production safety,but also threaten people′s daily life on the ground.Therefore,it is very necessary to detect the distribution of underground mined-out area.This paper establishes several geological models of mined-out area and sinking area.The full-tensor responses of microgravity anomaly in mined-out area and sinking area on the surface are simulated and calculated,and the characteristics of full-tensor microgravity anomaly responses are compared and analyzed.The simulation results are consistent with the theoretical analytical results,which can provide the basis for high-precision microgravity anomaly detection in mined-out area or sinking area. |
