Abstract:
To solve the gas problem of complex tectonic stress zone in Yangdong Coal Mine,for the gas geological characteristics,the gas comprehensive control measures were chosen. Continuous verification was conducted at 8263 face with complicated geological structure; and the results show that the new technology can solve gas safety of the fault and collapse column and their stress concentration zones.The technology ensures safe and speedy drivage of the working face and realizes safe and high-efficient mining of the working face.
