通过分析煤对瓦斯的吸附作用,指出温度和瓦斯压力对煤体的吸附量影响显著,瓦斯压力越大,温度越低,吸附量越大。吸附温度对吸附常数a,b都有显著影响,a随温度的升高而降低。煤体放散瓦斯的速度符合文特式和孙重旭式,在初期,瓦斯放散的速度极快,并迅速衰减,决定突出强度。
The analysis of gas adsorption on coal pointed that temperature and gas pressure have significantly effect on the adsorption amount of coal, the greater the gas pressure and lower the temperature, the greater the adsorption capacity. Adsorption temperature have a significant effect on the adsorption constants a, b, a decreased with temperature increasing. The gas release rate matches the formulation of wente and sun chongxu, at the beginning the gas diffusion fast and quickly decay, which decides to outburst strength.
