| Groundwater of mining area refers to the underground soil storage in rich mi neral resources, in the mining activities in order to ensure the safety of mining efficiency and discharged to the outside of the water. As a concomitant of mining activities, just as mined groundwater is generally the water quality is quite good, but is the result of efflux, the quantity of water resources of a certain extent less, quality to a certain extent variation. The value source of groundwater resources in mining areas from two aspects: one is the natural generation, two is a human creation. Natural generated value, because without any treatment, people wi-l l have a natural demand for the natural resources, and the ground water resourcees renewable relatively poor form scarcity. The creation of human values, embodied in the groundwater resources are developed for a variety of purposes can use, meet the needs of people in different aspects, the value added.The local Yunnan metal mines in Ge jiu tin mine have long enjoyed a good reputation as amine, in the long-term production activities, a large number of groundwater will generate the random discharge, did not make full use of the valuable groundwater resource, make the groundwater polluted and wasted, so decided to carry out economic evaluation of mining produce groundwater, calls attent-i on to the use of mining groundwater. I have repeatedly to mine tunnel inside, the surrounding businesses and residents, and on the basis of reading a lot of literature, established the economic evaluation of groundwater resources in mining area as the research object, defines the concept of groundwater resources evaluateon scope economy in mining, put forward the existence of old GAOSONG field mining area groundwater resources value and the use of management problems,using economics theory, utility theory of value, ecological value theory, the value of environment, the combination of theory and practice from the perspective of an old GAOSONG field mining area groundwater resources, water quality, water resource sutilization and management of the specific implementation of the ev-aluation and selection and value construction, the method of evaluation system of. In view of the current situation of mine, and provided some countermeasures and suggestions for utilization and management of groundwater of mining area in the future.The main conclusions are as follows:(1) The concept of evaluation, from mine water resources evaluation of water resources the extension of mining area groundwater resources economic evaluat-i on concepts, defines the groundwater resources in the economic evaluation of mining boundary.(2) Through field investigation, the pit interior surrounding factory visits and interviews that GAOSONG field surrounding residents, groundwater resources i n mine area has great potential market, the enterprise not only, and the residents are willing to pay a certain cost to enjoy pure mining area groundwater resources.(3) By analyzing the economic value of water resources constitution system, by the availability of data, estimation accuracy, using benefit coefficient allocation method, market value method, environmental value theory from the three aspects of industry, residents living and ecological environment for the economic evaluation of groundwater resources value of water in mining area. And the use of recovery cost method for the economic evaluation of water quality of groundwater resources mining value.(4) From the groundwater resources in mining areas with the current situation of management to analysis, now the water, pipe water properly, according to the blueprint for the future development of the mining area periphery to formula-t e the corresponding suggestion for the management of groundwater resources utilization of mine counter measures. |
