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。Take a anthracite Coal Mine as an example, through changing moisture content of coal, and analysis tectonic coal gas adsorp- tion and desorption rules under the condition of different moisture content by simulation method, and determine characteristics of tecton- ic 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.
