充水矿山疏干区覆盖型岩溶塌陷动态风险评价
Dynamic risk evaluation of covered karst collapse in the drainage area of karst water-filled mines
摘要
Abstract
In recent years,karst water-filled deposits have formed a wide range of drainage zones during mining,and a series of karst collapse disasters have frequently occurred in the drainage zones,seriously threatening the lives and properties of the people.Ground collapse occurred many times around Dazhishan mining area as early as in the 1970s,and dynamic risk evaluation is an effective way to prevent collapse disasters,and will be the main trend of future research.In this study,the large-scale drainage area formed during mining of karst water-filled deposits in Dazhishan mining area was taken as the study area,and the dynamic risk evaluation system of karst collapse considering the dynamic change of groundwater level was constructed by applying the weighted information value method.The evaluation results show that from July 2022 to January 2023,the overall risk of the study area shows a decreasing trend,and the distribution of risky areas at all levels is relatively fixed,but the risk level of some areas is also changing with time.The results of the dynamic risk evaluation provide technical support for the monitoring and early-warning deployment of karst collapse in the study area,and at the same time provide reference value for the risk evaluation of overlying karst ground collapse in other similar karst water-filled mines in the drainage area.关键词
