The application idea of using stagger arrangement to achieve simultaneous extraction of coal and gas

With the depth and intensity of coal mining increased,the probability of the occurrence of gas disaster also increased,more attention has been paid to the simultaneous extraction of coal and gas.This paper is dedicated to find more possible effective methods which can improve coal mine gas extraction rate and realize the safety and efficient production of high gas coal mine.From the aspect of reforming roadway layout and contacting the movement characteristics of the overburden when use stagger mine roadway arrangement after mining the first face,and combining stagger roadway arrangement with existing coal and gas extraction technologies,the application idea of using stagger arrangement mining seam to achieve simultaneous extraction of coal and gas was put forward.This paper made a corresponding predicted that this method has advantages in security ang economy compared with the traditional methods.advantages need to be verified by specific engineering practice.And this application idea need to be verified by specific engineering practice.
