金属矿山地下开采安全评价方法研究

Study on the safety assessment method of underground metal mine

金属矿山地下开采引发的灾害形式多样、机理各异,系统安全评价指标体系难以统一确定。本文以层次分析法为理论基础,建立一套综合的评价方法,并结合目前金属矿山灾害事故的特点和规律,用比较矩阵确定各致灾作业形式的权重,从而提高了矿山安全评价的准确性和科学性。

Calamities in underground metal mines are usually with various forms and different mechanism, so the safety assessment index＂ system can＇ t be the same. Based on the method of analytic hierarchy process, this paper puts forward an integrated assessment method, which improves the veracity and scientificity of underground mine safety as- sessment, combining with the characteristics and rules of calamities and using matrix matching method to ascertain the magnitude ratio of all kinds of the guiding calamities forms.
