摘要/Abstract

摘要： 为了更加合理地评价冲击型煤与瓦斯突出,采用指标临界值及分级数方式,从地应力、煤层瓦斯、煤岩物理力学性能3方面,研究冲击型煤与瓦斯突出指标等级判据;建立基于层次分析法(AHP)和逼近理想解排序法(TOPSIS)冲击型煤与瓦斯突出倾向性等级评判模型,并用实际工程案例验证模型的合理性。研究表明:基于AHP-TOPSIS的冲击型煤与瓦斯突出预测结果为中等危险性,与实际案例评价相符;地应力条件为冲击型突出发生的主要原因,瓦斯因素次之,煤岩物理力学性能影响最小;煤岩结构、瓦斯压力、瓦斯动力现象、煤岩破坏类型及煤体坚固性系数对冲击型煤与瓦斯突出影响较大。

Abstract: In order to evaluate coal-gas outburst induced by rock burst more reasonably, grading criteria of coal-gas outburst indicators were studied from three aspects of in-situ stress conditions, coal seam gas, and physical and mechanical properties of coal by using index critical value and classification number method. Then, a grading evaluation model of outburst tendency was established based on AHP and TOPSIS. Finally, its rationality was verified through actual engineering cases. The study show that the prediction result of proposed model is medium risk, consistent with actual cases. In-situ stress is a major reason for occurrence of rock bursting with coal-gas, followed by gas factor and physical and mechanical properties of coal have the least impact. Specifically, coal structure, gas pressure, gas dynamic phenomenon, coal damage type and coal solidity coefficient have a greater impact on such outburst.

Key words: coal, coal-gas outburst induced by rock burst, analytic hierarchy process (AHP), technique for order preference by similarity to ideal solution (TOPSIS), influencing factors
