Description	Journal: Iop Conference Series: Earth and Environmental Science Aiming at the problem of abnormal gas emission in fully mechanized caving face during mining, the law of gas emission from coal and rock in front of working face is studied, and the main factors of gas emission from coal wall and goaf are analyzed. This paper puts forward the method of gas drainage by surface drilling, which provides a new way to solve the gas overrun of upper corner, return air roadway and working face under the condition of high-intensity fully mechanized caving mining in extra thick coal seam, which has great engineering significance to ensure the safety and efficient production of the mine.
