In order to solve the problem of hole collapse and low construction efficiency in the process of soft media gas extraction. A full hydraulic drilling machine with high drilling speed, cross belt construction ability and strong process adaptability has been developed. Through the industrial test, the high efficiency of the drilling machine in the construction of soft coal gas extraction hole is verified, and a method of drilling efficiently in the soft broken coal seam is explored.
