Experimental Study of Penetrant Solution Impact on Gas Desorption

For the question of gas exceeding limit in the coal face, independent research and development gas desorption experimental measuring device was used under the condition of external solution invasion, according to the experimental data and curve with and without penetrant solution invasion impacting on gas desorption, it can be seen that there is the influence law of external solution invasion to gas desorption, and the article discusses the feasibility and implementation way by means of water lock effect of penetrant solution to prevent gas exceeding limit in the coal face. The results of study have some reference and application value to prevent gas exceeding limit in the coal face.
