Optimization and Application of Safety in Rapid Withdrawal Process of Fully Mechanized Mining Face
In order to solve the problem that the mining efficiency of the fully mechanized working face is reduced due to the unreasonable layout of the withdrawal channel and the unreasonable design of the corresponding support technology,and the roof subsidence,roof fall and other accidents occur during the withdrawal of the working face,take 1108 fully mechanized working face as an example,based on the analysis of its roof and floor conditions and relative position,the last mining net hanging technology,support technology and hydraulic support withdrawal technology in the withdrawal process are studied.This research result can guide the specific implementation of the 1108 withdrawal process.
