摘　　要：新庄矿主井井筒穿越多个含水层,各含水层富水性强弱不同。为了给建井设计和施工提供可靠的水文地质参数,利用新庄矿井主井井筒检查钻孔抽水试验资料,根据地下水动力学原理,采用"潜水完整井"、"承压转无压完整井"、"井壁进水非完整井"和Theis公式准确地预算出主井主要含水层的井筒涌水量。The main shaft of Xinzhuang Coal Mine passes through multiple aquifers, the water yield property in each aquifer is different. In order to provide reliable hydrogeological parameters for the design and construction of building mine shaft,using pumping test data of the main shaft inspection hole in Xinzhuang Coal Mine,according to the principle of groundwater dynamics, and by using the ＂submersi- ble full well＂ formula, the ＂ confined-unconfined fully penetrating well＂ formula, the ＂ sidewall inlet partial penetrating well＂ formula and the ＂Theis＂ formula,the water inflow of the main shaft in the main aquifer was accurately predicted in the paper.
