黔西县洪水沟煤矿的设计能力由原来的3万t/a扩大到现在的15万t/a,最大日用水量为418.85m3/d,其中生活用水量为99.05m3/d,生产用水量为169.80 m3/d,消防用水为150m3/d(一次性补充用水)。
通过分析取水点——地表水取水点不同保证率的来水量、可供水量及煤矿取水的可靠程度;分析矿井涌水量、可供水量及可靠性;分析煤矿用水的合理性及可行性;分析煤矿退水的合理性和可行性等为其合理用水提供可靠的水资源依据,达到合理配置水资源,以及水资源的可持续利用,为促进社会经济可持续发展,确保实现水资源开发、利用、配置、节约、保护和治理的综合目标得以实现。
通过分析黔西县洪水沟煤矿的取用水是合理的,取水水源是可靠的、可行的,取水对水资源状况和其他用户用户影响不大,退水对也不会影响受纳水体的水域功能。
Abstract
Qianxi county's coal mine flooding ditch from the original design capacity of 30,000 t / a now expanded to 150,000 t / a, the largest daily water demand for 418.85 m3 / d, of which water consumption for 99.05 m3 / d, production Water, 169.80 m3 / d, fire water to 150 m3 / d (one-time add water).
By analyzing the water points - different surface water intake points to ensure that the rate of water, coal and water for the water level of reliability; analysis of mine discharge, water availability and reliability of coal mine water is reasonable and feasibility ; Withdrawal of mine water is reasonable and rational water use for their feasibility to provide a reliable water resources based on a reasonable allocation of water resources and sustainable use of water resources, to promote sustainable socio-economic development, to ensure the realization of water resources The development, utilization, allocation, conservation, protection and management of integrated
