针对大石河通过导水通道引起矿井采空区积水增加的现状，为了解决采空区积水引起的煤矿安全生产问题，在掌握矿井水文地质条件的基础上，分析了矿井涌水增加的原因及地表水对矿井的危害，并利用多功能注浆材料采用地面帷幕注浆和煤柱加固的方法对导水通道封堵和提高煤柱防水能力，消除由于地表水引起的矿井突水隐患。在施工过程中优化施工工艺和设备，并采用瞬变电磁和钻孔窥视检验治理效果。研究结果表明：地表水与小煤窑采空区沟通，形成持续高压水，严重影响工作面安全回采。根据工程需要研发了多功能注浆材料，该材料能够适用水灰比（6.0～0.8）∶1.0，凝结时间为4～41 min，抗压强度为0.84～18.70 MPa，且可通过调节水灰比满足不同施工需求，帷幕注浆和煤柱加固的综合治理方法可在阻断导水通道的基础上加固煤体，提高煤柱防水能力，防止突水事故的发生。对比帷幕注浆加固前后瞬变电磁探测结果发现，加固区域电阻率大幅提高，视电阻率由5 Ω·m提高至40 Ω·m，富含水区范围缩小，钻孔窥视结果表明注浆加固能够较好加固破碎煤体，浆液能够填充煤体裂隙，胶结情况良好，通过注浆加固消除了矿井突水隐患，保证了工作面安全回采。

As for the current situation of mine goaf water accumulation caused by Dashihe passing through the water channel, in order to solve the problem of coal mine safety production caused by water accumulation in goaf, after investigating mine hydrogeological conditions, the reason of the increase of mine gushing water and the hazard of surface water to mine were analyzed. Moreover, multi-function grouting materials were used to block the water channel and strengthen the waterproof ability of coal pillar by ground curtain grouting and coal pillar reinforcement to eliminate the hidden trouble of mine water inrush caused by surface water, operating process and equipments were optimized in the engineering, and transient electromagnetic sensor and borehole peep were used to check the treatment effect. The results show that continuous high pressure water was formed due to the penetration between surface water and goaf in the small mine, which seriously affected the safety of working face mining. Multi-functional grouting materials were developed according to the engineering requirement. The material can be used by the water-cement ratio of（6.0～0.8）∶1.0，the setting time was 4～41min and the compressive strength was 0.84～18.70 MPa，and the various engineering requirements can be attained by adjusting water-cement ratio. The combination between curtain grouting and coal pillar reinforcement can enhance the coal body to strengthen the waterproof capacity of coal pillars and prevent the water inrush accident. By comparing the results of curtain grouting reinforcement detected by transient electromagnetic sensor, it  was found that the electrical resistivity increased rapidly in the reinforcement area and the range of rich water area reduced，the apparent resistivity  was increased from 5 Ω·m to 40 Ω·m. In addition, it was found by borehole peep that grouting reinforcement can better strengthen the broken coal bodies, slurries could backfill the fractures in the coal body and the effect was better. Safe mining in face was guaranteed by eliminating water inrush in uderground mine through grouting reinforcement.
