In order to ensure the smooth construction the inclined shaft pass through the water-bearing quicksand stratum, according to the dewatering mechanism, through theoretical calculation and analysis, a reasonable flow, well depth and layout are determined. The tube well dewatering is adopted to improve the stability of the surrounding rock by reducing the water level of local aquifer and strengthening the temporary support, so that the soil is consolidated, to prevent the working face collapse, roof caving accident, which lays the foundation for rapid and safe construction of the inclined shaft, and provides the reference for the construction of the wellbore under similar conditions.%为使斜井顺利穿越含水流砂层,根据管井降水机理,通过理论计算分析,合理确定管井流量、深度及布置方式.采用管井降水技术,通过局部降低含水流砂层水位标高,并加强掘进工作面临时支护,提高了工作面围岩稳定性,使土体产生固结,防止了工作面溃砂、冒顶事故,为斜井井筒快速、安全通过含水流砂层奠定了基础,也为类似条件下井筒施工提供了参考.
