Abstract:

In order to control the stability of roadway roof strata under complex conditions，the support

scheme was studied with the track roadway of 11503E working face in Zhaizhen Coal Mine as the research

background. Aiming at the problems of high support density and insufficient support reliability of roadway，

the continuous strengthening control technology of roadway roof strata is put forward. Based on the continu⁃

ous strengthening control mechanism of roof strata，a multi-stage thick anchored rock beam strengthening

support technology of 'one-level normal support-two-level strengthening support-three-level pressure re⁃

lief and anti-scour' is proposed，and the technical parameters of support are determined. According to the

performance comparison and practical application with the original support，the optimized support scheme

can play a better support effect，and can effectively reduce the cost of roadway support，improve the econom⁃

ic benefits of enterprises，and play a reference role for the control of roof strata in the same type of roadway.
