摘 要:为准确判识煤层的煤与瓦斯突出危险程度,便于突出矿井的分级管理,重点研究了突出危险评价指标和指标权重赋值方法,基于属性数学理论建立煤层突出危险性的组合赋权综合评价模型。模型选用瓦斯压力、瓦斯放散初速度、煤的破坏类型、坚固性系数、埋深比及煤厚变异系数6项指标构成评价指标体系,采用乘法集成法组合层次分析法和相似系数法进行指标赋权,借助属性评价模型对石壕煤矿M8煤层进行突出危险性评价。研究表明:M8煤层瓦斯压力及瓦斯放散初速度严重超标,瓦斯抽采钻孔出现强烈喷孔现象,判定该矿属于强突出矿井。In order to determine coal and gas outburst risk degree of coal seam accurately and be easy to manage outburst mine hierarchically, studying risk indicators of outburst and index weight assignment method emphatically, we propose an attribute synthetic evaluation model for predicting the risk of outburst based on attribute mathematics theory and combined weight. An evaluation index system is established, which includes gas pressure, the initial speed of methane diffusion, the damage type of coal, the rugged coefficient, the depth ratio and coal thickness coefficient of variation. The multiplicative integration method is used to combine analytic hierarchy process and similarity coefficient method, and M8 coal seam of Shihao Coal Mine is evaluated by the model. The results showed that gas pressure and the initial speed of methane diffusion exceeded the standard seriously, gas extraction drilling appeared intense jetting phenomenon in M8 coal seam. So, Shihao Coal Mine belongs to strong outburst coal mine.
