井筒涌水量预测方面存在的问题与对策探讨

Discussion on Issues and the Way to Deal with in Shaft Water Inflow Prediction

井筒涌水量预测对矿井设备的选型、建设速度和投资成本等都有着到重要的影响。在分析近年来国内大量新建矿井井筒掘进实际涌水量与井筒检查孔预测涌水量误差较大的基础上,针对传统的预测方法("大井法"和比拟法)存在的预测方法缺乏创新、预测基础数据收集不够全面、预测精度欠佳的问题,提出了完善传统预测方法,加强深部含水层岩石均匀性研究,重视施工设计、提高施工质量,建立勘查单位、矿井设计部门和生产建设部门间的沟通协调机制,正确对待预测结果,树立防范意识的对策。

The shaft water inflow prediction has great impact on mine equipment option, construction pace and capitalized cost etc. In light of recent years domestic large amount newly built mines biggish discrepancy between shaft excavation actual water inflow and shaft pilot hole predicted water inflow, in allusion to conventional prediction methods （＂virtual large-diameter well method＂ and analo- gy method） existed issues such as lack of innovation, insufficient basic data acquisition, poor accuracy etc., thus countermeasures of perfecting conventional prediction method, strengthening deep part aquifer lithologic homogeneity study, paying attention to construc- tion design, improving construction quality, establishing mechanism of communication and coordination between exploration, mine de- sign, production and construction departments, dealing seriously with predicted result and establishing awareness of prevention put for- ward,
