What Are The Finishing Steps After Working Underground With Steel Arch Supports?
1. After the coal is cut, the Steel Arch Support must be moved immediately.
2. After removing the Steel Arch Support, each operating handle is pulled to the stop position.
3. Clean up the floating coal, gangue and coal dust in the Support Arch, and arrange the pipelines in the bracket.
4. After the squad leader and the inspector check and accept the Support Arch, the work can be stopped after passing the test, the tools are counted, and the spare parts are placed.
5. Explain in detail the situation, faults and existing problems of the hydraulic support in the shift to the hydraulic support worker. After lifting the well, fill in the hydraulic support work record as required.
6. When personnel pass through the moving frame area in the working face, they must contact the support worker 3m away from the moved support. After the Mine Roof Support is completed and the moving frame is stopped, the personnel can pass through with the consent of the Mine Roof Support worker. Under special circumstances (such as broken roof, moving racks, etc.), personnel can only pass after the supporter has completed the operation and has been allowed. All personnel are strictly prohibited from forcibly passing through the area where the frame is being moved.
