Background technique

With the increase of mining depth in production mines, the in-situ stress, surrounding rock stress and deformation are complex and diverse. Bolt-mesh support is widely used in roadway mining due to its good supporting effect, wide application range, and flexible strain according to roadway conditions. However, in the current process of roadway excavation, the efficiency of mechanized excavation is very high, and the speed of roadway support is far behind the excavation speed. There is a serious mismatch between the excavation and anchor time, which results in the roadheader's footage time being far less than the total working time, and a large amount of time the roadheader is out of work for supporting operations. One direction to solve the serious mismatch in the time of excavation and support is to realize the parallel operation of excavation and support.
