我国是缺水国家,淡水资源总量2.8万亿m~3,居世界第6位,人均水资源却只有世界人均水量的1/4,水资源的分布也极不平衡,淮河以北的广大地区水资源仅占全国的19％,而煤炭资源却占全国总量的75％,形成了北方地区的富煤贫水格局。全国40％的矿区严重缺水,已制约着煤炭生产的发展。因此开发、管理、利用好煤矿水资源(包括煤炭开采排放的矿井水和废污水的资源化)对煤炭工业可持续发展具有重要意义。本文以马碲沟煤矿矿井水处理为例,探讨解决矿井水处理的途径和方法。
China is a water-scarce country with a total freshwater resources of 2.8 trillion m3, ranking 6th in the world. Its water resources per capita is only 1/4 of that of the world average, and the distribution of water resources is also very unbalanced. The vast north of the Huaihe River Regional water resources account for only 19% of the country’s total, while coal resources account for 75% of the national total, forming a pattern of poor water rich in coal in the northern region. Severe water shortage in 40% of the country’s mining area has restricted the development of coal production. Therefore, it is of great significance to develop, manage and make good use of coal mine water resources (including mine water and waste water recycling from coal mining) for the sustainable development of coal industry. In this paper, Ma Weiguang coal mine water treatment as an example, to explore ways and methods of mine water treatment.
