在干旱的贺兰山区,地下水是矿区的主要水源。石炭井矿区、大峰沟矿区及贺兰山磷矿的水源地均在干河沟里。由于采用了不同的取水方法,其取水效果差别很大。实践证明,本地区采用机井或大口井的方法在干河床内取水,不但取水效果欠佳,且井口泵房、管路等设施的安全难以保障,常易受雨季期间洪水的破坏。为克服上述缺点,1977年贺兰山磷矿用坑道的方法取水,不但免除了以上弊病,而且还得到令人满意的取水效果。
In the arid Helan Mountain area, groundwater is the main source of water in the mining area. Carboniferous mine area, Dafenggou mining area and Helan Mountain phosphate rock are in the dry river ditches. As a result of different methods of taking water, its water intake varies greatly. Practice has proved that the use of a large well or large wells in the region to take water in the dry riverbed, not only poor water intake, and wellhead pumping stations, pipelines and other facilities is difficult to protect the security, often vulnerable to flood damage during the rainy season. In order to overcome the above shortcomings, the Helan Mountain Phosphate Mine in 1977 adopted the method of taking waterways, which not only avoided the above disadvantages, but also obtained a satisfactory water abstraction effect.
