中文摘要:
      以贵州省2020年矿产资源大精查项目——福泉市大湾磷矿为研究场地,通过对钻孔地下水位动态长期监测及综合研究,揭示磷矿区的矿床地下水动态特征。研究结果表明,远离开采区的地下水动态与气象密切相关,成因属气象型,但矿山集中开采区及相邻地带区域地下水逐年下降,气象因素对地下水动态影响退居其次,反映出磷矿区地下水动态主要受矿山开采矿井抽排水控制,矿床充水含水层处于长期连续的疏干状态。研究成果对未来大湾磷矿开采抽排水设计,矿山防治水,以及保障矿山安全生产具有指导意义。
英文摘要:
      It takes the 2020 intensive survey project of mineral resources in Guizhou Province as the support,and the Dawan phosphate deposit in Fuquan as the research site,based on the long-term monitoring and comprehensive study of the groundwater level dynamics in the borehole,the dynamic characteristics of the groundwater in the phosphate mining area are revealedThe results show that the groundwater dynamics far from the mining area is closely related to the meteorology,and the genesis is still of meteorological type,but the groundwater in the concentrated mining area and the adjacent area decreases year by year,and the influence of meteorological factors on the groundwater dynamics is secondary,it shows that the groundwater regime in the phosphate mining area is mainly controlled by the pumping and drainage of the mine,and the water-filled Aquifer of the deposit is in a long-term continuous drainage stateThe results of this study will provide guidance for the design of pumping and Drainage,mine water prevention and control,and mine safety in the future of Dawan phosphate mine
