干河煤矿防水闸墙设计方案研究

Study on Design Scheme of Waterproof Gate Wall in Ganhe Coal Mine

山西干河煤矿受奥灰水影响较为严重,水文地质条件较为复杂,并具有突水可能性。因此,根据干河煤矿二采区1-203工作面巷道实际情况为设计背景,提出了两种设计方案,通过理论计算和数值模拟方法对上述两种方案进行了深入研究。研究结果表明,新型注浆楔形防水闸墙结构形式符合耐压条件的同时工程量也明显减小,优势较为明显,为未来矿井的水害防治提供了宝贵经验。

Ganhe Coal Mine in Shanxi Province is seriously affected by Ordovician limestone water,with complex hydrogeological conditions and the possibility of water inrush.Therefore,according to the actual situation of the 1-203 working face roadway in the second mining area of Ganhe Coal Mine,two design schemes are proposed,and the above two schemes are deeply studied by theoretical calculation and numerical simulation.The research results show that the structural form of the new grouting wedge-shaped waterproof gate wall not only meets the pressure conditions,but also significantly reduces the quantities,and has obvious advantages,which provides valuable experience for the prevention and control of mine water disasters in the future.
