摘　　要：论文阐述了煤与瓦斯突出机理的特征,指出六盘水区域煤与瓦斯突出机理为综合作用假说机理,研究了六盘水煤矿的瓦斯赋存特征,认为构造作用、煤变质程度、煤层厚度及埋深较大是对瓦斯赋存起控制作用,对区域煤与瓦斯突出的影响因素进行研究,认为瓦斯、地应力及煤物理力学性质是其主控因素。This paper expounds the characteristics of coal and gas outburst mechanism,points out that the mechanism of coal and gas outburst in Liupanshui coal mine is a hypothesis mechanism of comprehensive action,studies the gas occurrence characteristics of Liupanshui coal mine,considers that tectonic action,coal metamorphism degree,coal seam thickness and buried depth are the controlling factors of gas occurrence,and the influencing factors of regional coal and gas outburst are studied In situ stress and coal physical and mechanical properties are the main controlling factors.
