近距离煤层煤体瓦斯解吸特性对比实验研究

Experimental Study on Gas Desorption Characteristics of Close Distance Coal Seams

为了研究近距离煤层煤体瓦斯解吸特性差异,以平煤五矿近距离煤层己_(15)煤和己_(16-17)煤为例,通过基本参数测定及煤体瓦斯解吸规律测定,获得了2种煤的瓦斯解吸特性。从瓦斯解吸特性的角度,解释了近距离煤层突出危险性差异的原因。

To study the differences of gas desorption characteristics in close distance coal seams, the VI 15 and VI 16-17 coal of No. 5 coal mine of Pingdingshan was taken as an example, based on the determination of the basic parameters and gas desorption, the gas desorption characteristics of two kinds of coal were obtained. From the view point of gas desorption, the difference of outburst risk in close distance coal seams can also be explained.
