摘　　要：赣南某铀矿山3号充填井近地表段处于含水层内,井筒涌水量大,井筒锁口段下部坍塌形成空区,充填井形成积水段,导致安全隐患,影响矿山生产。为减小井筒涌水对井下排水和安全生产的影响,采用“修复3号充填井”的工程治理方案,具体实施了封堵井筒坍塌区、帷幕注浆堵水和修建山坡截洪沟等工程措施。结果表明,充填井筒涌水量明显减少,修复工程有效防止了井筒中积水段的产生,解除了安全隐患,矿山生产恢复常态。修复充填井治理方案为类似矿山地质环境中井筒涌水的工程治理提供了参考。The near surface section of filling shaft No.3 in a uranium mine in southern Jiangxi is located in the aquifer,the water inflow of the shaft is large,the lower part of the shaft lock section collapses to form an empty area,and the filling shaft forms a ponding section,resulting in potential safety hazards and affecting the mine production.In order to reduce the impact of shaft water inflow on underground drainage and safety production,the engineering treatment schemes of repairing filling shaft No.3 is compared and demonstrated,and the scheme of repairing filling shaft No.3 is preferred as the final treatment project.Engineering measures such as plugging shaft collapse area,curtain grouting water plugging and building hillside flood intercepting ditch are taken.The results show that the water inflow of the filling shaft is significantly reduced,the repair project effectively prevents the ponding section in the shaft,removes the potential safety hazards,and the mine production returns to normal.The treatment scheme of repaired filling shaft provides a reference for the engineering treatment of shaft water gushing in similar mine geological environment.
