针对煤矿冲击地压危险性综合评价指标的不确定性和不相容性,基于集对分析方法,将多个指标合成为一个可反映冲击危险级别的联系度参数,建立了煤矿冲击地压危险性预测评价的集对分析模型.将该模型应用于富力煤矿276工作面和华亭煤矿回风顺槽掘进工作面,选用开采深度、煤层上方坚硬岩层距煤层距离、构造应力集中指数、顶板岩层厚度特征参数、煤的单轴抗压强度和煤的冲击能量指数等6项指标,分别对其冲击危险性进行了预测评价.计算结果与工程实践符合,表明所建立的集对分析模型能够合理评价区域冲击危险等级.
According to the uncertainty and incompatibility of comprehensive evaluation index of coal mine rockburst, based on the set pair analysis method, a number of indicators are synthesized into a contact degree parameter that can reflect the impact hazard level, and the risk of rock burst of coal mine is established This model is applied to the working face of 276 working face of Fuli Coal Mine and the return air inlet of Huating Coal Mine. The mining depth, distance between the top of the coal seam and the coal seam, tectonic stress concentration index, roof rock thickness The uniaxial compressive strength of coal and the impact energy index of coal and so on, respectively, the impact criterions are evaluated respectively.The calculated results are consistent with the engineering practice, which shows that the established set pair analysis model can reasonably evaluate Regional impact hazard level.
