摘要
荆门子陵铺石膏矿段面积3.54 km2,形成采空区1.202 km2,累计发生地面塌陷23次,塌陷面积达0.157 4 km2。通过对该矿段四干渠分水闸周边地面塌陷区的形态规模、变形特征、形成因素、破坏模式分析和发展趋势预测,提出该区域采空区综合治理和地面塌陷地质灾害防治监测预警的措施和方法,在实际运用中取得良好效果。
The area of the originalmining area of Zilingpu ore section is 3.54 square kilometers. The area of goaf is 1. 202 square kilometers. The cumulative surface collapse occurred 23 times, subsidence area reached 0. 1574 square kilome- ters. Through shape scale length, deformation characteristics, forming factors, failure mode analysis and development trend prediction, the paper puts forward comprehensive treatment of goal and measures and methods of geological disaster pre- vention and control of surface collapse, obtaining good results in practical application.
