Note: 1. The next section of the surface will be transported to the fault at 427m.
2. Construction of the Taiyuan No. 1 surface to the 446m variable level roadway.
3. Taishao No. 1 operation is expected to see the bottom coal seam floor along the roadway construction 70m. When the construction along the roadway is 35m, see the coal seam roof.
Special technical measures for uncovering coal safety are as follows
1. When the coal point is 10m (the total length of the construction is 465m), the location is given by the geodetic department, and the implementation measures are started;
2. The cycle progress is 0.8m, the maximum control top distance is 1.0m, and the minimum empty top distance is 0.2m.
3, strengthen the anchor cable lag working face is not allowed to exceed 5m.
4. For every 1.6m of construction, make a 2m deep exploration along the direction of the roadway. Sight-seeing arrangement: the top of the roadway center is 1.5m downward.
5. After exploring the coal seam, the ventilator checks the gas condition of the gas exploration to see if there is gas outburst. If the gas emission is abnormally large, the working surface is stopped, and the exploration hole is tightly sealed with yellow mud. At the same time, the interlock switch will be powered off, and the ventilator and the leader on duty will report to the mine dispatching room. The personnel will be evacuated to the full wind pressure and enter the wind side to be avoided.
6. Before each cycle and during the eye-catching process, the ventilator must focus on the working face to supervise and inspect the blasthole and the working surface gas. If the gas exceeds the limit and immediately stop working, and the power supply is cut off, the ventilator and the leader on duty will The mine dispatching room reported that the personnel were evacuated to the full wind pressure and entered the wind side to avoid the construction.
7. Power off the power supply before releasing the gun. After the gun is released for 30 minutes, the ventilator can check the gas concentration before sending power. During the shooting process, the power supply is not allowed to send power.
8. The length of the shooting line must be greater than 150m. The firing line must not have a clear joint.
9. Strictly implement the "one shot three inspections" and "three-person interlocking" shooting system.
10, the pressure self-rescue device is not more than 20m from the head of the palm.
11. The air cylinder mouth is not more than 5m away from the working surface, and the air cylinder cannot have holes. Ensure that the working face has sufficient air volume.
12. After the construction roadway has completely entered the coal seam, the original “Taiwan No.
