Water Resources Integrated Development And Utilization Of Mining Subsidence Area

China is a water-scarce country, traditional methods cannot solve the water shortage problem very well, and new water resources development and utilization will be the theme of water conservancy. In addition to the traditional source of water resources, development and utilization of unconventional water resources is undoubtedly a major way to solve the water crisis.Deep development of coal resources took great economic benefit while caused mining subsidence water resources depletion, soil damage and a series of ecological and environmental problems. This paper examines the matter from storm water harvesting angle to solve coal mining subsidence problem, promotes a utilization model combined with water supply, water storage, and building wetlands. It should raise the utilizations ratio of surface water, promotes a new thoughts to the research of Comprehensive treatment and rational utilization of water resources in the coal mining subsidence. The main contents of the thesis are as follows:(1) To solve coal mining subsidence problems, the paper describes its studies both in and abroad, proposes different modes of development and utilization of water resources to different conditions of the mining subsidence. Engineering and non-engineering measures are important initiatives to comprehensive utilization of water resources in such area.(2) In accordance with the main water source is river, the paper studies different types of water quantity based on the theory of river water resources structure, calculates the regional flood resources utilization quantity.(3) There is no water features for storage capacity in coal mining subsidence area, so system analysis method is used to establish water input, output and storage conditioning systems whose center is the coal mining subsidence. In using of real long-term hydrological data to regulate water balance calculation, the water supply and demand results of the system is derived. At last the paper proposes a rational disposition scheme of water resource.
