Comprehensive mechanical rock drift excavating process

Abstract

The invention relates to a comprehensive mechanical rock drift excavating process, which adopts a comprehensive mechanical rock drift operation line, and is characterized in that the comprehensive mechanical rock drift operation line comprises a comprehensive rock drift excavating machine, a crawler-type movable belt conveyer and a crawler-type movable wet-type mortar spraying machine, wherein the comprehensive rock drift excavating machine is used for excavation and supporting operation, the crawler-type movable belt conveyer is used for conveying rocks from a working surface to the outside, and the wet-type mortar spraying machine is used for carrying out wet-type mortar spraying sealing to a rock drift. In the rock drift excavating process, the comprehensive mechanical rock drift excavating machine which integrates rock cutting, rock loading, rock carrying and supporting is adopted for rock drift excavating, and the wet-type mortar spraying machine is used for spraying mortar, so that the rock shift operation can be carried out. According to the invention, the original blasting and rock-breaking process is cancelled, the construction process is simplified, the production with potential safety hazards can be greatly reduced, and the safety performance is greatly improved.

Description

technical field [0001] The invention belongs to the underground development technology of coal mines, and is especially suitable for the comprehensive mechanized development operation of underground rock roadways in large, medium and small coal mines. Background technique [0002] In the underground development technology of coal mines, the main traditional method of tunneling in various coal mines is blasting, and the support methods are combined support of bolts, anchor cables, joists, and anchor nets. The gun excavation is drilled, charged, and blasted with an air-leg pneumatic drill; the gangue falling from the blasting is first manually broken and then transported out of the working face by a rock rake machine; protection; and then the spraying operation. There are following problems in this adopting rock roadway excavation construction method: [0003] 1. The excavation section of the roadway is small: the excavation section is generally 15m 2 Left and right, when t...

AI Technical Summary

Problems solved by technology

[0004] 2. Non-mechanized operations, blast hole construction and gangue crushing are all manual operations. The construction of the top bolt and anchor cable of the supporting roadway is still a single pneumatic drill operation, while the construction of the side anchor rod and anchor cable is operated by a hand-held pneumatic drill. The thrust source of drilling Because of human arms and arms, the labor intensity of workers is high

[0005] 3. Slow construction speed

[0006] 4. Low efficiency: Since drilling, crushing gangue, and bolt and anchor cable support are all manual operations, there are many construction workers, resulting in low operating efficiency

[0007] 5. Low safety factor: Construction workers work alternately at high altitudes, and the construction safety factor is low

[0008] 6. Poor working environment: the gun smoke after blasting and the dust during spraying are likely to cause lung diseases of construction workers and affect the health of workers

Still can't get rid of the traditional technology of drilling holes and blasting rocks, and still can't solve the problem of rock roadway excavation with complicated technology and slow excavation progress
