【 摘 要 】

In order to solve the problem of continuous tension in production from low driving efficiency of coal mine and excessive mining. Daliuta coal mine put forward the idea of using the rapid drivage system for roadway tunneling innovatively. The system optimized the excavation process and used remote control to alpine bolter miner to cut coal. It used straddle type anchor to support the roof and used belt reloader to carry coal. The parallel operation of digging and supporting and one time forming of top support is realized. Thus, the safety of operation and drivage efficiency are greatly improved. It is effective to relieve the difficulty of the tension of coal mines. It came up a lot of problems in the application process of speedy drivage system. But through continuous optimization and improvement, the advantages of speedy drivage system get better play. Since the speedy drivage system used in Daliuta coal mine, it created world's record of the maximum daily footage of 102m, the maximum monthly footage of 2514m, per capita ergonomics reached 1.33m/capita.
