摘　　要：针对榆神矿区在地质勘查阶段水文地质勘探程度不足,难以满足现代化煤矿建设和生产需求的问题,在补充勘探时应做好浅埋煤层的精细勘查。在分析榆神矿区现阶段面临的主要水文地质问题的基础上,明确了水文地质精细勘探的必要性和主要勘查内容,认为需要对萨拉乌苏组、烧变岩、直罗组砂岩、洛河组砂岩等主要含水层进行重点勘探,查明其厚度、分布、岩性、孔隙裂隙发育特征、水文地质参数等,进而查明煤层及其与含水层、隔水层的空间赋存关系,精准确定小煤窑的采空区范围,编制各类等值线图,预测矿井涌水量。通过水文地质的精细勘查,能够为煤矿安全高效生产提供详细数据和资料,进而实现矿井水害防治和地下水资源保护。Based on the research on the geological and hydrogeological conditions of Yushen mining area,it is believed that during the geological exploration stage,the degree of hydrogeological exploration is insufficient to meet the needs of modern coal mine construction and production.Therefore,when conducting supplementary exploration,it is necessary to conduct detailed exploration of shallow coal seams,as well as major aquifers such as Salawusu Formation,burnt rock,Zhiluo Formation sandstone,and Luohe Formation sandstone,especially to identify their thickness,distribution,lithology,pore and fissure development characteristics,hydrogeological parameters,etc.We identify the spatial occurrence relationship between coal seams and their aquifers and aquifuges,determine the goaf range of small coal mines,investigate the undulating shape of the bedrock top interface,etc.,prepare various contour maps,and predict the water inflow of the mine,in order to provide detailed data and materials for safe and efficient production of the coal mine.Through precise hydrogeological exploration,we aim to achieve the prevention and control of mine water hazards and the protection of groundwater resources.
