Supporting Technology Speedy Drivage Roadway in Shoushan No.1 Coal Mine

For the problem of long unsupported roof distance and time, roadway supporting difficulties under the condition of deep roadway rapid advance in Pingdingshan Coal Group Shoushan No.1 Coal Mine, by analyzing the main factors which influence the stability of surrounding rock of roadway under rapid advance, we propose the principle of joint active support, and select the roadway support way of bolt joint shoulder anchored cable through numerical simulation. The theory and practice proved that the implementation of joint active support and shortening the time of supporting process could effectively improve the stability of surrounding rock of roadway under the condition of rapid advance.
