平顶山矿区近构造区域煤与瓦斯突出规律研究

摘要

以平顶山矿区发生的突出事故作为研究对象，从构造的影响对其进行研究，并对其发生突出原因进行了分析。研究结果表明：工作面从断层的下降盘向上升盘方向推进时更容易突出，通道形态是影响煤与瓦斯突出发生的主要原因，通道大小是影响突出发生的次要因素，瓦斯的释放条件是影响地质构造区域突出规律出现的唯一因素。%Taking coal and gas outburst accident of Pingdingshan mining area as the research object,from the influencing aspect of structure,the authors analysed the reason for outburst accidents.The results show that,when working face is advancing from falling wall of fault to rise wall,it is susceptible to appear outburst accidents.Channel morphology is the main factor which affects the happening of coal and gas outburst,the channel size is the secondary factor of influencing the happening of coal and gas outburst,and the conditions of gas releasing is the only factor which affects the outburst happening laws of geologic zone.
