| 摘 要： | 为了寻找突出煤层的高效解突技术,根据工作面突出煤体的显微结构照片和FLAC3D力学软件分析结果,认为软煤低透和高能瓦斯是煤与瓦斯突出的必要条件,提出了突出煤层的循环加压瓦斯透析解突技术.结果表明:低透气性是突出煤层的特点,也是瓦斯抽放的主要障碍,瓦斯加压预裂透析煤体技术,提高煤体瓦斯渗透率的同时可以解突,实施该技术可以在高瓦斯突出煤层工作面实现煤与瓦斯共采.

| Abstract: | It is important to look for a method that can efficiently solve the problem of coal and gas outburst from working face.Based on the micro-structural photographs and the analysis by FLAC3D mechanics software,we hold that low air permeability and high energy are necessary conditions for coal and gas outburst and put forward a technique of gas diffusing dialysis circularly pressuring the coal body to prevent coal and gas outburst from taking place.The results show that 1) the coal body pressurization technolog... |
