简介:摘要院贵州省毕节市黔北煤矿区草堤井田历史悠久。历史上有大量小煤窑分布于可采煤层的露头线附近.为了使草堤井田断层发育规律、煤层特征得以理清,本文在普查地质工作的基础上,选择条件较好的露朗背斜南东翼作为首采地段,详细查明首采地段的构造发育程度、可采煤层特征、水文地质条件、主要可采煤层工程地质特征、煤层瓦斯等开采技术条件。本文评估了矿区煤的储量,并对矿区开发做了前瞻判断。
简介:摘要:论文 分析了黄花滩铁矿区构造承压含水层(带) 的地质、 水文地质条件,详细分析研究了矿区 地下水的赋存 条件、地下 水化学特征 。基本查明 了矿区构造承压含水层(带) 的水文地质条件及 成因机制,通过 对其 水文地质条件及 成因机制 的深 入分析 研究,为后期矿山开发设计利用提供了水文地质条件参考依据,同时也为该类型矿区水文地质条件调查、勘查和供水水源地的勘查工作起到了借鉴指导意义。 summary : T his paper analyzes the geological and hydrogeologic conditions of the structural confined aquifer ( zone ) in Huanghuatan i ron m ining a rea, and analyzes in detail the occurrence conditions and chemical characteristics of the groundwater in the mining area. The hydrogeologic condition and the genetic mechanism of the structural confined aquifer (zone) in the mining area are basically ascertained, and the hydrogeologic condition and the geological conditions are provided for the later mine development and design by the in-depth analysis of the hydrogeologic conditions and the genetic mechanism. At the same time, it also has a reference significance for the investigation of hydrogeological conditions, and the exploration of water supply sources in this type of mining area.
