| 摘 要： | 以宿南矿区为例,通过对"四含"沉积物沉积前的古地形、沉积物的颗粒大小与磨圆度、物质来源,得出沉积相特征.结合区内"四含"水文地质特征,分析了"四含"富水性与沉积相之间的关系.经数值模拟计算的结果和沉积相与富水性之间的关系的综合分析,将区内"四含"分为强富水区、中等富水区和弱富水区三种类型,为煤矿一阶段水平开采前对于确定煤岩柱类型和留设合理的煤岩柱高度提供了技术支撑.

| Abstract: | Taking Sunan mining area as an example, the characteristics of sedimentary faces is obtained by analyzing systematically the topography before sediment, the degrees of roundness, the sizes of sand grains and sources of materials. Based on the analysis on the results of mathematic simulation and the relationship between sedimentary faces and water-enrichment, the yielding property of the aquifer is divided into three sections, namely, the section abounded with most groundwater, the section with groundwater partially and the section rarely. All of these provide a basically technological support to the determination of safety coal-rock pillar types and the reasonable height of coal-rock pillar to avoid groundwater rush during first level mining. |
