| 摘 要： | 以某矿无烟煤为例,通过改变煤中水分含量,用实验模拟方法研究了不同水分含量条件下的构造煤的瓦斯吸附-解吸规律,确定了构造软煤在不同水分、不同破坏类型和不同压力条件下的瓦斯解吸特征,为煤与瓦斯突出预测、煤层注水和煤矿瓦斯灾害的防治提供一定的理论依据。

| Abstract: | Take a anthracite Coal Mine as an example,through changing moisture content of coal,and analysis tectonic coal gas adsorption and desorption rules under the condition of different moisture content by simulation method,and determine characteristics of tectonic soft coal gas desorption under different water,different failure types and different pressure condition,this support a certain theoretical basis for gas outburst forecast,seam water infusion and coal mine disasters. |
