摘要
为了对煤与瓦斯突出事故进行有效的预防与控制, 分别从孕育和突出两个阶段阐述了瓦斯在煤与瓦斯突出中所起的作用, 指出了煤层吸附瓦斯和裂隙瓦斯对煤的物理力学性质的影响;由于空隙瓦斯的存在, 加剧了煤体失稳破坏的过程; 特别指出突出的主要能源来自于瓦斯的膨胀能; 并根据这一结论提出了相应的防突措施.
In order to carry out effective prevention and control for coal and gas outburst accident, elaborated the role of gas in coal and gas outburst from the two stages of pregnant and outbursting, and pointed out the influence of the adsorption gas and crack gas of coal seam to the physical and mechanical properties of coal.The existence of gap gas aggravate the course of coal body damage; Especially pointed out the expansion energy of gas is the main energy of outburst, and put forward corresponding control measure according to the conclusion.
