Abstract
To take effective and reasonable gas control technology to solve the problem of gas overrun, analyzed the gas emission distribution by setting up monitoring stations of the way the result show that the gas concentration distribution is not balanced in space; the gas concentration distribution increased with the yield and the air distribution in the upper corner, When the air distribution reach a certain value the gas concentration dropped sharply; during the period of the pressure in fully mechanized caving face,the gas concentration increased from 0.42%~0.56% to 0.64%~0.9%, the gas emission quantity increased by more than 50% of the conclusion.关键词
