| 中文摘要: |
| 矿床充水因素是矿床水文地质特征分析的一项重要内容,它通过对矿床充水水源、充水通道及充水强度的影响因素进行分析和总结,对矿床开采技术条件提供理论依据。文章以兴仁县槽箐地区煤矿床为例,对矿床充水因素进行分析,认为该区煤矿床的主要充水水源为大气降水和长兴组岩溶水,主要充水通道为岩溶裂隙和顶板冒落裂隙带。由于龙潭组相对隔水层的阻隔,茅口组灰岩强含水层对矿床开采不构成底板突水威胁。 |
| 英文摘要: |
| The water filling factors of ore deposits is an important content on analysis of hydrogeological characteristics of ore deposits, which analyze and the summarize through the influencing factors of water source, passage and water flow rate, and provide theoretical basis for mining technical conditions. This article takes coal bed in Caoqing area of Xingren county as an example to analyze the water filling factors of ore deposits. I think the main water filling source of coal deposits in the area are atmospheric precipitation and karst water in Changxing Formation,mainly water passages are karst fissure and fissure zones of roof caving. Due to the confined aquifer in Longtan Formation, the limestone of Maokou Formation is not a floor water inrush threat to the mining of the deposit. |
