矿山工程安全评价方法的探讨

Discussion on the Safety Evaluation Method of Mine Engineering

矿山企业在采掘过程中面临的灾害主要有瓦斯、水灾、火灾、冒顶、片帮等,为了避免出现安全事故,针对上述各种灾害分别建立了相应的安全评价函数,确定了评价因子的评分标准和矿山工程危险性等级。以贵州某矿5#煤层为例,对其底板运输上山的瓦斯、水灾、火灾、冒顶、片帮等灾害进行了评价,其评价结果与现场情况一致,证明了该安全评价方法的可行性和可靠性,为类似地质条件的巷道施工安全评价提供了参考。

The main disaster such as gas,flood,fire,gas,roof caving,wall caving may be met in the mining process.In order to avoid the various safety accidents in mining process,the corresponding safety evaluation function of the above disasters are established respectively,and the grading standards of evaluation factors and mine engineering risk grades are determined.Taking a mine in Guizhou province as the research example,the evaluation results of the disasters such as gas,floods,fire,roof caving,wall caving in 5 #coal seam floor are consistent with the actual site situation,so,it is the scientific and relia-bility of the evaluation method proposed in this paper are proved,besides that,it can provide reference for the safety evaluation of tunnel construction in similar geological conditions.
