Abstract: This method using detonator to break the faultage rocks existing in the synthesis exploitation working face costs many alternate work-time and brings potential safe hazard, causes equipments to be damaged usually, even leads to explosive accidents such as gas explosive and coal-bed explosive. In connection with these problems, Zhaizhen colliery of Xinwen mining group uses the static cracking technique which is a kind of inexplosive methods to break faultage rocks, and proves that the method can increase the technical and economic benefit of coal synthesis exploitation and be beneficial for the safety in production with important practical significance. The treatise introduces the construction technics and application of the static cracking technique.
