| Huayingshan secondary folding mountain fold, fracture development, the oldest strata exposed to the Lower Paleozoic on the Cambrian system, the lack of Paleozoic Devonian and Carboniferous of unification, exposed for a more complete picture of the ancient Permian and Mesozoic Mesozoic Triassic to Jurassic. According to the region exposed lithologic characteristics of the aquifer, water-based and lead-rich water-based differences in strong water-bearing rocks are divided into groups, in - strong aquifer group in the weak water-bearing rock group, a relatively impermeable rock group of four types, of which strong group of water-bearing rocks are mainly distributed in five layers, and the Triassic slope Ray Group I (T2l), Jialing Group (T1j) and Group 3 +4 Feixianguan paragraph (T1f3 +4) and the EC under the Permian Mao I group, Qixia Group (P1m + q) in the. The region carved out of a total of 31 secondary karst water system, including the West Wing 9, East Wing 22.In this paper, fold mountain Huayingshan hydrogeological conditions, analysis of the aquifer water-based rock group of the rich features of the karst water flow system and the relationship between spatial overlay, through calculation of hydrology and water resources by means of analysis of groundwater in karst water system in a centralized and decentralized excretion study of karst water system in the cycle of evolution model. The main conclusions of the Working Papers are as follows:Enrichment under natural seam zone "against the home-style" system of karst water circulation patterns, and is based on the level of movement-based multi-aquifer groundwater systems; natural state coal-rich belt "shun home-style" karst water systems in general circulation models for the groundwater precipitation groundwater surface water. In the natural state, the tunnel site area of the karst groundwater system in the aquifer is relatively independent of the basic and mutual exchange of water does not exist. Natural state, water supply system to karst water circulation patterns can be summarized as follows for the chemical zoning of karst groundwater in space law has obvious from the recharge zone to the groundwater discharge areas are seeing a gradual increase in salinity of the regional trends.Coal-rich belt "against the home-style" karst water system model of the cycle of evolution is the natural state of the lower water content between the karst water system for the gradual evolution of karst water in between layers - both mine water of the aquifer system of the new. At the same time, as a result of the collapse of mined-out area cracks the communication with the overlying carbonate strata aquifer hydraulic body contact occurred, and thus a large number of dewatering of overlying strata into the aquifer and aquifer systems to increase vertical replenishment.Enrichment in the coal belt, by artificial interference with the "shun home-style" of the evolution of karst water system model mainly by the natural state of evolution for the cyclic model, precipitation→mall part of the groundwater surface water or groundwater→groundwater→precipitation→cut layer groundwater model of groundwater circulation.Tunnel site area of karst water systems of coal-bearing strata within the water, when the tunnel drainage, due to falling water tables, the groundwater system to break the original balance of the water through faults within a certain range so that a relatively impermeable layer into aquitard to funnel involve dewatering of underground water systems within the scope of a degree of hydraulic continuity, then, the system of coal-bearing formation water will be exposed to two functions, one hydrogeochemistry oxidation; Second, hydrodynamic drive role.Supply water to the karst water system evolution model circulation mainly by the natural state, from the recharge areas of groundwater discharge zones to a gradual increase in salinity of the regional trend of karst groundwater flow into the market changed, HCO3 pumping Department the scope of water-smaller, SO4-type water, with the continuous pumping, the groundwater extracted from the original water-HCO3 type water gradually into SO4.
