Abstract: In view of the situation that No.10 seam do not have condition of pressure relief mining, the protective fully-mechanized coal mining face setting in 5.1 meters thick soft rock was designed to control regional gas in order to solve the problem of high gas and outburst in No.8 seam and No.9 seam in the third level of Luling Coal Mine. Taking geological guarantee technologies as the support, multiple-level optimization design of mining parameters and system modification was carried out, overall planning of surrounding rock control of mining face and roadway was drawn up and the plan of hydraulic support selection and equipment matching was implemented, III11 soft rock mining face with mining height of 2.0 m and strike length and tendency length is 860 m and 104 m was put into practical engineering with multi-disaster prevention and control technology and reasonable labor organization as the safeguard.
