浅析金属矿山主井涌水治理方法

Analysis on the Treatment Method of Gushing Water of Main Shaft in Metal Mine

地下水是产生井筒涌水的主要水源,研究表明矿区地下水资源丰富,主要源自大气降水,而矿区断裂普遍发育,构成了涌水通道,为主井涌水提供了条件。通过对比分析,并结合矿区井筒地质概况,选择静水抛渣注浆封水、壁后注浆充填截水作为井筒涌水的治理方案,在此基础上,介绍了涌水治理的施工工艺、主要技术参数及排水问题。在井筒涌水淹井后,采用构筑止浆垫和钻孔注浆等方法,实现有效堵水,同时,完成了井筒掘砌。

Groundwater is the main water source producing borehole water gushing in the research area,research shows that groundwater resources are rich in this mine and mainly come from atmospheric precipitation.The development of fault in this mine constitute the gushing water channel,it provide condition for gushing water of main shaft.Through comparative analysis,combined with the shaft geology of the mine,we select hydrostatic throw residue grouting sealing and after-wall grouting cut-off water as the management program of borehole water gushing.Based on this,we describe the construction process,main technical parameters and drainage problems of gushing water management.After the shaft gushing water and submergence,we can block water effectively and complete shaft excavation puzzle by using the methods of build pulp pad and drilling grouting.
