Abstract:
In order to improve the gas treatment capacity of "three soft" low-permeability coal seams, promote new technology, new technology and new equipment, Zheng Coal Group decided to carry out research on long-distance directional drilling technology, implement "reducing roadway with holes" and "replacing roadway with holes", reduce regional gas treatment roadway projects, and promote the transformation of gas extraction engineering to "pumping fast and saving". Through the investigation of the current situation of directional drilling technology at home and abroad and the mines belonging to the Group, the direction of directional drilling technology research suitable for Zhengzhou mining area is proposed to provide technical support for mine safety production.
