| 中文摘要: |
| 英坪磷矿位于瓮福矿田高坪矿区英坪矿段内,目前矿山规划向深部开采。区内前人研究程度高,地质成果丰硕,但对开采技术条件方面的研究较少,特别是对深部磷矿床水文地质条件的研究有所欠缺。本文通过地质、水文地质勘查及水文地质试验等方法,结合前人研究成果,从水文地质角度,对英坪磷矿床水文地质条件进行研究,填补了该区磷矿床开采技术条件方面研究的空白,丰富了区内研究成果。研究结果表明,英坪磷矿水文地质条件中等,为顶底板直接进水水文地质条件中等的岩溶孔洞裂隙充水矿床；采用水文地质比拟法预测首采地段正常涌水量为24178.39 m3/d,最大涌水量为55368.51 m3/d,为英坪磷矿防排水系统设计提供了重要参数,为此类矿床的研究提供了借鉴及参考。 |
| 英文摘要: |
| Yingping phosphate mine is located in the Yingping ore section of Gaoping mining area of Wengfu ore field. The predecessors in the area have a high degree of research and fruitful geological achievements, but there are few researches on the technical conditions of mining, especially the research on the hydrogeological conditions of deep phosphate deposits. This time, through the methods of geological, hydrogeological exploration and hydrogeological tests, combined with the previous research results, from the perspective of hydrogeology, the hydrogeological conditions of the Yingping phosphate deposit were studied, which filled the research on the technical conditions for the mining of phosphate deposits in this area. The blanks have enriched the research results in the region. The research results show that the hydrogeological conditions of Yingping phosphate mine are moderate, and it is a karst hole and fissure water-filled deposit with moderate hydrogeological conditions of direct inflow of roof and floor. The water volume is 24178.39 m3/d, and the maximum water inflow is 55368.51 m3/d, which provides important parameters for the design of the waterproof and drainage system of Yingping phosphate mine, and provides a reference for the study of such deposits. |
