【摘要】 淮南矿区矿井涌水量为1787万吨/年,利用率仅为44%,大量外排的矿井水不仅污染地表水、土壤,还造成了水资源的严重浪费。此外,随着煤炭深度开采的增加,高温加剧了井下热害的程度,如何实现深部矿井热水的资源化利用,也是发展煤炭环保资源化产业所面临的重要问题。本文在查阅国内外相关文献的基础上,以淮南谢一煤矿为例,通过分析其矿井水来源、涌水变化量及水质特征,对其资源化可行性进行了评价。利用矿井水正交混凝试验、单因素试验、柱状沉淀试验和改性滤料过滤试验的结果,确定后期构筑物的运行参数,并增设反渗透淡化除盐步骤。依据试验参数设计了最优物化处理工艺,即：预沉调节→混凝→沉淀→过滤→反渗透→消毒,并进行平面和高程布设,在分析淮南矿区地温分布规律及其影响因素的基础上,以热害严重的潘集矿区为研究对象,分析其深部矿井水质特征,建议采用地源热泵技术来实现深部热水的资源化。最后,依照“排供结合,分质分用”的原则设计资源化利用途径,并做了社会、经济和环境效益分析。图[40]表[20]参[80]更多还原

【Abstract】 The annual mine hydraulic discharge is 17.87 million Ton per year in Huainan mining area, but the utilization rate is only 44%. The large number of mining water not only pollutes the surface water and soil, but also causes a serious waste of water resources. Besides, with the deepening of coal mining, the high temperature will aggravate the extent of geothermal. How to achieve the deep mining water resource utilization, which is the major issue we have to face when to develop the industry of coal environmental protection resource utilization.Based on consuliting the relevant literature at home and abroad, Xieyi coal mine of Huainan mining area was taken for example. After its mining water source, mine hydraulic discharge and water quality characteristics were analyzed, the resource utilization feasibility was evaluated. According to these results, including mining water orthogonal coagulation experiment, single factor experiment, columnar precipitation experiment and modified filter media filtration experiment, the running parameters of structures have been determined and the reverse osmosis desalination has also been added. The optimization materialized treatment process by experimental parameters has been designed, that is regulation→coagulation→sedimentation→filtration→reverse osmosis→disinfection, and the plane and elevation have also been designed. After the background of geothermal characteristics and influence factors of Huainan mining area were analyzed, Panji mining area which the most serious geothermal was taken for example, the quality of mining water in deep coal mining was analyzed, some suggestions were provided, which used the ground source heat pump technology to achieve the deep mining hot water resource utilization. Finally, in accordance to the principles, the "drainage and supply combined, different water quality for different use" was used to design the utilization ways, and the social, economic and environmental benefits were evaluated.Figure [40] Table [20] Reference [80]更多还原
