摘　　要：基于灰色关联分析法和模糊综合评判理论,综合考虑煤体结构、瓦斯压力和含量、地质构造、煤层埋深以及煤厚等因素,利用勘探钻孔所测瓦斯资料,建立了勘探钻孔煤层瓦斯突出危险性评价模型,并以重庆松藻矿区为例,对矿区勘探钻孔附近煤层瓦斯突出危险性进行了评价。结果表明:模型评判结果与矿井实际生产揭露情况一致,评判结果可靠。该模型避免了以往勘探阶段仅利用单项指标或简单综合指标进行突出危险评价的不足,使评价指标更全面,评判结果更可靠。Based on the grey relational analysis method and fuzzy comprehensive evaluation theory,according to considering factors comprehensively such as coal structure,gas pressure and content,geological structure,burial depth of coal-bed and coal thickness,the gas outburst proneness evaluation model of exploration drilling was es-tablished with gas data of exploration boreholes in this paper.It used this model to evaluate the gas outburst proneness in the coal seams in Songzao mining area.The result shows that the evaluation result of the model is re-liable,which is in accordance with mining reality.The model avoids the deficiency of gas outburst proneness evaluation according to single index or simple comprehensive index in previous exploration stage,as a conse-quence,making the index much more comprehensive and the result more reliable.
