【摘要】：近年来，随着煤矿生产在开采深度上不断增加，煤矿突水日趋严重，突水事故多有发生，给人民的生命与财产带来了极大的损失。本文将模糊数学理论应用到安全评价当中，，首次对我国煤矿突水安全程度进行综合评价，对我国煤矿突水研究与防治具有一定的指导意义。本文在分析研究了多种安全评价方法之后选择了专家调查法、层次分析法与模糊综合评价法。采用事故致因理论和层次法原理对影响煤矿突水的危险源进行了综合辨识，并据此构建了全面的煤矿突水安全评价指标体系。在此基础上对指标体系中各影响因素进行了定性定量研究，本文对5类23个因素作为影响煤矿突水的主要因素进行安全评价。首先采用专家调查法确定模糊评判指标的隶属度，并用层次分析法（AHP）确定所有评价指标的权重，然后将模糊数学理论和层次法有机结合起来构成模糊综合评价系统并将此评价系统应用到Y煤矿突水安全评价过程中，由此得出Y煤矿突水的模糊向量集A=[0.3267,0.3365,0.2048,0.1210,0.0119]，根据最大隶属度原则可知Y煤矿突水安全等级属于B级(较好)。
[Abstract]:In recent years, with the continuous increase of mining depth in coal mine production, water inrush in coal mine is becoming more and more serious, and water inrush accidents often occur, which brings great loss to people's lives and property. In this paper, the fuzzy mathematics theory is applied to the safety evaluation, and it is the first time to comprehensively evaluate the safety degree of water inrush in coal mines in China, which has a certain guiding significance for the research and prevention of water inrush in coal mines in China. After analyzing and studying many safety evaluation methods, this paper chooses the expert investigation method, the analytic hierarchy process method and the fuzzy comprehensive evaluation method. Based on the theory of accident cause and the principle of hierarchy method, the comprehensive identification of the dangerous sources affecting water inrush in coal mines is carried out, and a comprehensive evaluation index system of water inrush safety in coal mines is constructed. On the basis of this, qualitative and quantitative study was carried out on the influencing factors in the index system. In this paper, the safety evaluation of 23 factors of 5 categories as the main factors affecting the water inrush in coal mines was carried out. Firstly, the membership degree of fuzzy evaluation index is determined by expert investigation method, and the weight of all evaluation indexes is determined by analytic hierarchy process (AHP) (AHP). Then the fuzzy comprehensive evaluation system is constituted by combining the fuzzy mathematics theory with the hierarchical method, and the evaluation system is applied to the evaluation process of water inrush safety in Y coal mine. Therefore, the fuzzy vector set A = [0.3267U 0.3365U 0.2048U 0.1210U 0.0119] of water inrush in Y coal mine is obtained. According to the principle of maximum membership degree, the safety grade of water inrush in Y coal mine belongs to class B (better).
