Tectonic coal with low intensity, high energy storage, rapid desorption and low permeability are caused to the coal and gas outburst. The characteristics of tectonic coal are the important reason of gas accumulation, which to cause the coal mine disasters, and that is the essence reason of can not determinate gas content accurately and difficult extract CBM directly.
The research core is initial stage features of tectonic coal gas desorption,which based on the structure of coal. The test device has des...
