正台阶施工法在王庄煤矿大冒落区的应用

Positive-step Construction Method in Wangzhuang Mine Collapse Area of Application

根据王庄煤矿43M5运巷掘进遇到的实际情况,介绍了采用正台阶施工法过空巷大冒落区的施工方法,通过实践证明,与传统的施工方法相比,减轻了工人的劳动强度,保证了施工中的安全系数,提高了回采效率。

According to Wangzhuang 43M5 mine transportation roadway tunneling encountered the actual condition,introduces using Positive-step through empty roadway caving area construction method.Through the practice proved that,compared with the tradition construction method,reducing the labor intensity of the workers,ensureing the construction safety coefficient,improving the mining efficiency.
