Study on optimal allocation of karst water resources in Hanxing Mining Area

in order to change the karst water table continuous drop and the drop hopper continuously expanded staus in Hanmin Mlining Area and to realize the spring re-gushing,frstly with the investigation and the supply and demand balance analysis on the regional kart water resouces,the main causes of the spring no-ftow were the water mining value higher than the rering volune . Seccndar y.based on the karst underground waler system mocdel s the bas s,thesinmu ation pred cion showed tht if he eiing volume of the avaiable system retained and the mining voume unchanged.the karst water table would be coninLously dropped.the Huo spring ad the Bai Spring would be no water flow and the water ecolgic environment woult be continuously worst Therefor, with the id ea of the wateresouceregiona licaton.a water resourcesmanagement model was established to keep the water environment of Baiquan spring region continuousl geing better as the target. The domestic water in Xingtai downtown and the agrcutre water would be kept no change. As woll s the total mining volume of the water inBadquanArea wasless than the totareflig volume andother restiction condiions,the calcu ation showed that the optimized waler supply plan was obtained with the total water consumption volume reduced by 0.591 m1'/s and the tolal fling volume of Baiquan Area with a surplus of 0.29 m'ls and with the minus of the total mining volume. with the mod l simuiation pedction.accoding to the optinized plan.the underground water table in the spring area would be steadiy recovered and aftr10 years,Balquan and Dahuoquan springwater would be re-inflow.
