Xieqiao utilization of coal mine water

A pump can be replaced 4BA 8 (single-stage cantilever) or a 78 150S (single-stage double-suction type), usually only open one. Two of them installed in the mine water drainage pumping stations, for fire, green water; make full use of existing pipelines, laying a short distance required convergence pipeline. 3.6-benefit analysis of mine water purification treatment, industrial and miscellaneous solve water nearly 2000m. / D, accounting for the total water consumption in the industrial square (2751ms / d), 16 of Hebei Engineering College in 2003 73. Annual water savings of about 2O million,[link widoczny dla zalogowanych], reduced sewage charges nearly 15 million, total cost about 35 million / year. 4 Conclusion Xieqiao utilization of coal mine water 24h a day not only solve the problem of water supply, but also save water,[link widoczny dla zalogowanych], reduce production costs, reduce sewage charges,[link widoczny dla zalogowanych], and ultimately achieve economic, social and environmental benefits of unity.
