Study On The Water Supply And Drainage Optimization Design System Of Jin Long Iron

In the mining process,Selecting and mining activity is based on the quantity of supply and drainage water in the mine.For the restriction of the regional environment,water resources management,economic interests,Thus,the water of supply and drainage generally form an independent system in the general cause.Mine inflow water as one of the basic water is production of water supply.The treatment of mine waste water,not only related with the water of production and living,but also with mine gushing water can not be used and need to drain.Therefore,based on the prediction of mine gushing water,It is necessary to optimize the design of mine water,s system of supply and drainage,which is essential for use of water resources and environment protecting.It is also the need to solve the actual production and the improve of economic benefit of mine.In this article,we take Jin Long iron ore as an example,Based on the comprehensive analysis and collation of field survey data,According to the mining area environmental hydrogeological characteristics and specific natural ecological environment,While combined with design of mine roadway mining.Establishment of hydrogeological concept model and corresponding numerical simulation model.At last,the mining area of-400 m is forecasted.From the prediction results,it can be seen that the rate of initial mine water inflow is larger,and with the mining of the mine,the water inflow of the mine is gradually reduced,and finally gradually becomes horizontal.we predicted the water demand of the study area according to the annual output and the area of the mine area,the number of people participating in the work.It is known that the new water production is 5478m~3/d,the living water is 257.8m~3/d.Through the detailed analysis on the quality and quantity of mine drainage.we can find that the Yuxi River of water quality and the mine water inflow is good,all of which meet the production water.And the shallow groundwater is the better water source for mining workers.Mining production does not produce effluent,and mine drainage will be the use of all production.So mining area requires effluent waste water only domestic sewage.Living displacement is206.2m~3 /d.The design of mine drainage system,the tailings of convergence system become diversion system.Tailings in addition to accepting mineral waste water is no longer acceptable to living sewage.What,s more,domestic sewage through the corresponding treatment of formation water can be directly used for mining greening,the remaining water come into the mineral processing and recycling.Through this optimization,we can achieve the efficient utilization of water resources in the mining area.And provide an important reference for the design of drainage system about similar industrial and mining enterprises or adjustment of water supply and drainage.
