大断面黄土斜井塌方处理工程实践

Treatment scheme for the collapsed section of inclined shaft on large section and loess

为安全通过郝家梁矿副斜井塌方段,制定切实可行的塌方处理方案显得尤其关键。根据该井筒的工程地质条件与水文地质条件,分析了塌方原因,制定了通过塌方段的注浆处理方案,确定了迎头工作面管棚超前支护方案与壁后注浆充填方案的详细参数,按此方案实施后,顺利通过塌方段,保证了矿井的正常施工。

In order to safely get through the collapsed section of auxiliary inclined shaft of Haojialiang Mine, a practical and feasible collapse treatment scheme is needed. Based on the engineering geological and hydrogeological conditions of the shaft, the cause of collapse is analyzed, the grouting treatment scheme covering the collapsed section is proposed. The detailed parameters about the heading workface pipe-shed advance support scheme and behind-wall grouting scheme are determined. The collapsed section is successfully construction process of shaft is ensured. passed by the application of this scheme. Smooth
