摘要: 针对我国现阶段煤矿溃水溃沙灾害预测评价方法单一、防治手段被动等问题, 以薄基岩、厚松散层矿井为研究对象, 从影响溃水溃沙致灾的主控因素出发, 提出了以“沙层厚度、基采比、溃沙裂缝带发育高度、基岩风化指数、单位涌水量、饱水沙层厚度、渗透系数、采动影响指数” 为指标的溃水溃沙危险性多源信息分区方法, 建立了“区域转局部、高位截流接续” 的超前生产布局优化模式, 研究成果在神东矿区隆德煤矿成功应用, 提高了煤矿溃水溃沙预警评价的精准度, 为超前主动解决溃水溃沙问题提供了新理念。

Abstract:

For coal mines with thin bedrock and thick loose layers as the background, the occurrence of water and sand inrush disasters generally presents the characteristics of sudden and frequent occurrence. Such accidents are catastrophic and destructive. Production poses a great threat. Therefore, the key to preventing the occurrence of water and sand inrush disasters is to carry out advanced prediction, early warning and prevention work for such disasters. The multi-source information zoning evaluation method and the advanced production layout optimization technology provide a basis for the prevention and control of mine water and sand inrush disasters.
