【摘要】 随着采深的增加,高瓦斯煤层往往冲击地压和煤与瓦斯突出两种灾害并存,并相互诱发转化,以此为出发点,从灾害的发生条件、能量来源和破坏形式等方面分析了高瓦斯煤层冲击地压和突出的异同点;从瓦斯、应力和煤岩的物理力学性质等方面讨论了两种灾害的诱发转化机制;以实验研究和理论分析为基础,提出了两种灾害在孕育发生和发展等不同阶段的诱发转化条件.更多还原

【Abstract】 With the increase of coal mining depth,rockburst and coal-gas outburst usually coexist and mutually transfer in a high methane mine.Based on the understanding mentioned above,the similarities and differences of coal-gas outburst and rockburst have been analyzed in occurrence conditions,energy sources,and failure form,and so on.Induced transformation mechanism has been discussed from methane gas,stress and mechanical properties of coal and rock.Transforming conditions at occurrence stage and development stage have been proposed respectively by experiment and analysis.更多还原
