Abstract

This paper presents that 3th coal seam has a strong burst trend in Tangkou Coal Mine,the roof of the 3th coal seam has a weak burst trend,drilling based on 4 305 working face greatly exceeded the standard limits many times,the situation of preventing burst is very serious.According to geological conditions of coal seams in Tangkou Coal Mine,the technology of stress relaxation by deep hole was blasting used to discharge coal seam pressure,which has make expected effect and can guarantee safe and effective actual mining.
