我矿西部盲斜井设计倾角23°30″,井筒长度506m,初期采用P-30B耙斗装岩机出渣,φ800×600绞车提升,0.75m~3翻斗式矿车运输,每次提升一车。掘进开始时由于井筒浅,出渣矛盾尚不突出。随着井筒的不断加深,出渣矛盾日见明显。后改用2m提升机,钢绳粗,摘挂钩又困难,不安全感尤惑严重。有一次因挂钩失误造成飞车事故。鉴于这些情况,施工队一再要求改变提升方案,采用箕斗提升。
The design of blind shaft in west of mine is designed to be 23 ° 30 "and the length of wellbore is 506m. In the early stage, P-30B scraper bucket rock loader was used to lift slag, φ800 × 600 winch to lift and 0.75m ~ 3 skip bucket car to transport. Car.Due to the beginning of tunneling due to shallow shaft, slag discharge is not yet prominent contradictions.With the wellbore continues to deepen, the contradiction between the slag is obvious.Removed with 2m hoist, rope thick, picking hook and difficult, insecurity In the worst case scenario, a speeding accident caused by a link failure resulted in a continual request by the construction team to change its lifting plan and use a skip upgrade.
