摘要
文章就通过迈步式掘进临时支护装置的使用,解决了需要频繁割煤、支护,掘进效率相对低的问题,并通过实践应用,降低了工人劳动强度,提高了安全系数,取得了良好的掘进效益。
Through the use of the temporary support device for step excavation,the problem of frequent coal cutting and support and relatively low excavation efficiency is solved in this paper.Through practical application,the labor intensity of workers is reduced and the safety factor is improved.Thus,benefit has been obtained from excavation.
