【摘要】 水资源是与人类生存、社会发展息息相关的自然资源，是生态环境系统中最活跃和影响最广泛的因素。随着经济发展、人口增长和人们的物质文化生活水平的提高，世界各地对水的需求日益增长，水资源已成为当今世界各国社会经济发展的制约因素，引起普遍关注。我国北方地区主要建火力发电厂，建坑口电站更为经济节约，但建坑口电厂必须要解决水源问题。长期以来，由于技术所限和认识不足，矿井水被当作水害加以预防和治理，矿井水被白白排掉而未加以综合利用和保护。毫无节制的排水不仅大大浪费水资源、增加了吨煤成本，而且还导致地面塌陷、地下水资源流失、水质恶化等环境问题。因此，合理开发利用矿井水，使矿井水资源化，是解决矿区和坑口电站水源问题和矿井水污染环境问题的最佳选择。 本文在分析彬长矿区地质及水文地质条件的基础上，分别用“大井法”和水文地质比拟法计算了亭南井田、大佛寺井田、胡家河井田和小庄井田四矿的矿井涌水量，分析四矿矿井向大唐彬长坑口电站的供水能力，并对矿井水的水质进行了评价，研究了矿井水作为电站供水水源的可行性。在选择电站净水厂位置时，使用了近年新兴的蚁群算法，通过对基本蚁群算法进行改进，设计了用于平面选址问题的具有变异特征的蚁群算法，将其成功地应用于净水厂选址的最优化决策中。通过计算机仿真，分析讨论了蚁群算法中主要参数的选取，得到了用于解决本文问题的蚁群算法的合理参数。计算机仿真结果表明，该算法是有效的，并有广泛的应用前景。最后一章通过对矿井水资源化的效益分析，说明矿井资源化具有很好的社会效益、经济效益和环境效益。 本文不仅可以为我国北方地区的矿井水资源化提供一些参考经验，同时蚁群算法的成功运用也为工程建设的规划工作提供了一种可供使用的决策工具，有助于提高规划工作的科学性和效率，具有一定的理论和实际意义。更多还原

【Abstract】 The water resource is one kind of natural resources which is closely linked with the people’s living and the development of the society. It is one of the most active and far-reaching factors in the ecologic environment system. With the development of economy and the growth of the population and the rising of people’s living standard, the water requirement is increasing in every place of the world. The water resource has been a restrained factor of society and economy to all the countries in the world, arousing much attention. In north China, thermoelectric power station is often selected to build. And the pithead power plant is more economical, but the water source must be solved firstly. For a long time, because of limitation of technical and shortage of realization, mine water has been prevented and disposed of as water trouble. As a result, a large amount of mine water is discharged without comprehensive utilization. Immoderate discharge of mine water not only wastes a great deal of precious water resources, but also increases the cost of per ton coal and causes some environmental problems such as ground collapsing, ground water resource loss, water quality deterioration and so on. Therefore, rational utilization of mine water as resource is the best choice of solving the water source problem of mine site and pithead power plant and the environmental problem of mine water pollution.In this paper, based on analyzing the condition of the geology and hydrogeology in Binchang mine area, two methods, major diameter shaft method and hydrogeologic comparison method, were used to calculate the flowing yield of Tingnan colliery, Dafosi colliery, Hujiahe colliery and Xiaozhuang colliery. The water supply potential of the four collieries to the Datang Bingchang pithead power plant was analyzed and the water quality was evaluated. Then the feasibility of using mine water as the supply water source of the plant was researched. When selecting the address of water purification plant, the author used the ant colony algorithm burgeoning in recent years. By improving the basic ant colony algorithm, the author designed a mutated ant colony algorithm which adapted to solve the planar location problem and successfully applied it to the optimization problem of selecting location of the water purification更多还原
