煤矿采空塌陷的危险性预测评估与防治措施——以华亭矿区大柳矿井为例

Predictive evaluation and prevention on the ground-caved in with coal-mining:A case study from Daliu coal-mine,Huating mining area

煤矿开采后引发地面塌陷的危险性预测评估是煤矿地质灾害危险性评估的核心内容。以华亭矿区大柳矿井地质灾害危险性评估为例,介绍了煤矿采空引发地面塌陷危险性预测评估的基本内容及评估深度,并提出了较全面的矿区采空塌陷的防治措施,可以为矿井开采后防治地面塌陷提供指导。

Predictive evaluation on the ground-caved in with coal-mining is the core for the dangerous evaluation of geologic hazard in coal-mining.In this paper based on the case study from Daliu coal-mine in Huating mining area,introduced the basic content and degree to the predictive evaluation,then the comprehensive prevention measures sugguested,which can be guidful to prevent the ground-caved in with coal mine exploiting in the future.
