榆神矿区煤矿防治水的几点思考

Thoughts on mine water control and treatment in Yushen mining area

  • 摘要: 为了科学解释榆神矿区矿井涌水量较大的涌(突)水事件,为煤矿防治水奠定基础,分析了近年来区内发生的突水事件及矿井较大涌水情况,提出矿井较大涌水形成机理、红土层水文地质性质、矿井涌水量预测的准确性等疑问,阐述了突破“井田”范围,从区域上研究地下水系统和突水水源,关注延安组、直罗组、安定组、洛河组等砂岩弱富水含水层,从导水裂隙带中寻找突水水源,科学评价各岩(土)层的水文地质条件,采动岩层(含水层)渗透性演化以及探索矿井水害源头预防和区域治理思路等几点思考,提出应该从区域上认识水文地质条件及对煤矿涌(突)水的“贡献”,揭示矿井较大涌水形成机理,进一步加强水文地质补充勘探,准确识别含水层、隔水层及其空间赋存关系,探测大采高、大采面环境下导水裂隙带发育规律,并提出从区域上识别地下水强径流带和局部富水区的基础上,制定矿井水害防控措施的思路,为榆神矿区煤矿水害防治提供借鉴和帮助。

     

    Abstract: In order to scientifically explain the water gusting(bursting) events with large water inflow in Yushen mining area and provide basic information for mine water control and treatment, this paper analyzes the water bursting events and large mine water gusting situations in recent years, and questions such as formation mechanism of large water inflow in mine, hydrogeological property of red soil layer and accuracy of mine inflow prediction are put forward. It expounds how to break through the "mine field" scope and study groundwater system and water bursting source in terms of regions and focus on weakly water-rich aquifers such as Yan'an Formation, Zhiluo Formation, and Luohe Formation sandstone aquifer, looking for the water bursting source from diversion fissure zone. And the paper evaluates the hydrogeological conditions of each rock(soil) layer, permeability evolution of mining-induced strata(aquifers), as well as explore the source prevention of mine water disasters and ideas of regional governance. Based on the above thoughts, it puts forward that the hydrogeological conditions and the contribution to the water gusting(bursting) of coal mine should be recognized regionally to reveal the formation mechanism of large water inflow in mine. Hydrogeological complementary exploration to identify aquifer, water-resisting layer and their spatial occurrence relationship accurately should be strengthed. It is to explore the development law of water-conducting fracture zone under the environment of large mining height and large mining surface and put forward the prevention and control measures for mine water disasters based on strong runoff zone of groundwater with regional recognition and locally rich water area, which provides reference and help for the water disaster control and treatment in Yushen Coal Mine.
