The Installation Sequence And Method Of The Mine Face Underground Roof Support
The installation sequence of the working face Underground Roof Support is divided into two ways: forward and backward.
1. Forward installation: The installation sequence of the Tunnel Roof Support is consistent with the transportation direction of the Underground Roof Support, so that the transportation of the bracket is always carried out under the cover of the installed Tunnel Roof Support (the rear of the Steel Mine Supports are forward during transportation, which is convenient for steering and positioning). It is suitable for the high pressure of the working face and the broken roof. It is installed by section expansion method. Each section is 30~50m, and one section can be expanded to install one section, or it can be installed while expanding.
2. Receding installation: In the case of a good top plate, before installation, the slitting holes can be dug or expanded at one time, and the Steel Mine Supports are installed from the inside to the outside. In this way, the working face is easy to manage and has high efficiency, but the workload of reverse transportation of the required support and other equipment is large.
