Research On The Coupling Technology Of BaiYun Iron Mine Realm Outside Resides Orebody

This thesis combines National Science and Technology Project of Eleventh Five-Year study which relates to the column of key technology and equipment of open pitrealm resides orebody mining,and it colects more Dongjielegele Mine which is theRealm outside resides orebody of Bayan Obo iron ore design information.Then it drawsa detailed conclusion with the mining parameters, status of the stope, the geologicalconditions,etc. This paper mainly argues about the developing transport systemsdesign,production optimization and the optimization supply on spatio-temporal of Eastmine; The second aspect,it optimizes the matching of production capacity and long-termstability of the BaoGang Group ore production plan. The third area, it rearchs inCoupling with the optimal time and space of East mine ore suppled.Drawing areasonable conclusion which is suitable Dongjielegele Mine orebody theory andtechnology and safe and efficient recovery of this part of the iron ore resources.Designing three pioneering transportation system programs, you must make thebest choice basing on the amount of investment and cash flow. Through the applicationof net present value, net present value rate, dynamic payback period, internal rate ofreturn and the stability of the investment income, you can make economic optimizationanalysis. And you can come to reasonable conclusion, Road-Road jointly developingthe transport system under normal circumstances. Coupling the best solution with theEast mine original pioneering transportation system,you can draw coupling conditions:you should build the level car turned unloading platform distance thed south ofDongjielegele Mine west stope1602meters, Establishing the level construction of arailway flip platform under the lower part of the platform about1590meters. Thedouble track railway was formed by railway flip tai rotates through the west side of thestope South south. Double track railway integrates with the existing railway in the westof the rock station, forming a surface rail-road combined transport system. First therock of west stope is transported to the new highway unloading platform,thenreproduced shipped to rock stations though railway,last transported to the variousrailway dump by sub-species. When Ore is shipped to the East mine reproduced tai, itwill shipped by the East mine ore transportation systemSecondly, according to the design data of Dongjielegele Mine and BaoGang Groupfor Baiyunebo mine long-term stability plan, you will verify the production capacity and its optimization, then come to the best productivity is2million tons per year.Finally,according to the Group’s long-term plan and ensuring the stable supply,thebest moment for Dongjielegele Mine and Dong slope combination is that you willcompleted mines and construction of open-pit mining upper1388m in theDongjielegele Mine between2014and2017,The new ore production capacity willachieve2million tons per year. So you can achieve to replenish the decline of the Eastore production capacity.
