摘要
针对下峪口煤矿2#煤层出现的煤与瓦斯动力灾害问题,结合2#煤层区域瓦斯分布规律和煤与瓦斯动力灾害特征,按照煤与瓦斯复合能量系统理论,探索煤岩系统失稳过程中的能量来源及其耗散传递过程;提出应力主导型煤与瓦斯动力灾害预测方法,形成了一套"区域-局部"煤与瓦斯动力灾害综合防治技术体系和突出危险性预测敏感指标体系。
According to the problem of coal and gas dynamic disaster of 2~# coal seam in Xiayukou Coal Mine,combined with the regional gas distribution and the characteristics of coal and gas dynamic disaster of 2 # coal seam,this paper explored the source,dissipation and transfer of energy during the coal rock system being instable based on the theory of coal and gas hybrid energy system; The prediction method of stress-leading dynamic disaster for coal and gas was put forward. A set of integrated control system and the outburst risk prediction sensitive index system of coal and gas dynamic disaster have been established from region to local.
