东胜矿区哈拉沟井田地质灾害危险性评估

在详细调查研究区内地质灾害现状的情况下,对采煤引起的覆岩破坏、地表变形等进行了预测,并采用模糊综合评判二次评价模型对地质灾害危险性进行了综合预测。结果表明,研究区地质灾害现状不发育,但井下采矿工程对地面建筑物的危险性大,易引发崩塌、地裂缝、地面塌陷等灾害;预测地质灾害危险大区分布于井田北部、东部和南部,危险性中等区则位于井田中部。预测结果对于矿井的安全生产具有一定的指导意义。

Geological Hazard Risk Evaluation in Halagou Minefield, Dongsheng Mining Area

Based on detailed investigation of geological hazard status in the study area,predicted overburden destruction and surface deformation caused by coal mining.Through the use of fuzzy synthetic discrimination quadratic evaluation model,comprehensively predicted geological hazard risks.The result shows geological hazard status quo in the study area is not serious,but risk of underground mining engineering to surface structures is serious,easy to initiate hazards of landslide,ground fissure,surface subsidence etc.Predicted high risk areas are mainly distributed in the northern,eastern and southern part of the minefield,while the medium risk areas in the middle part of the minefield.The predicted result has certain guiding significance to mine production safety.
