“…The re-excavation roadway in the filling
body is a common engineering demand in mines. In order to solve the problem of instability and failure of the filling
body caused by the excavation disturbance in the filling
body and improve the comprehensive economic benefits of the technology, it is proposed to use the filling
body formed by membrane bag filling in the goaf and the steel arch frame to form a prefabricated load-bearing structure, reserve the required roadway space, avoid the safety risks caused by roadway excavation, and reduce the difficulty and cost of roadway support in the later stage. …”
