利用矿坑水发电在云南东川因民矿区的意义

摘要

Analyzed water resources situation of nationwide,southwest and Yinmin mining area,meanwhile it narrated the necessity about developing and using of mine water to generate electricity. The investigation and analysis showed that mine water is characteristic of high quality, steady flow and a big vertical drop. It benefits generate electricity. Based on those advantages,compute theory output and theory hydropower reserves,respectively 13 956. 21 kW and 1. 219 75 × 108 kW · h/a,bring benefits of ￥60 987 500/a with environmental benefit and social benefit%分析了全国、西南地区及因民矿区的水资源形势,叙述了开发利用矿坑水发电的必要性.通过分析调查认为:因民矿区矿坑水流量稳定、水质良好、水头集中且落差大,具备发电利用的有利条件.在此基础上,初步计算出矿坑水理论出力为13 956.21 kW,理论水能蕴藏量为1.21975 ×108kW·h/a,发电利用可带来60 987 500元/a的经济效益,同时社会效益和环境效益显著.
