stability analysis on the mining of hanging-wall ore in cangshang gold mine based on flac3d . prediction and control of surface strata movement by backfilling mining method ub sijiaying changyu iron ore . the paper proposed a mathematical model of calculating the energy consumption of the and the sag mill for ore processing according to the ore nature and technical parameters etc. the model was verified by industrial operation data. a lateritic nickel mine has large mining area and the deposit is distributed over a plane. the earthy ore is the main type, and it can be directly loaded into dump trucks by excavators and blasting is no need in mining. directing against the rock mass characteristics in no. 215 stope to locate in¡ª60m level of mining district ¢ò in jinshandian iron mine,a comprehensive technique by classified driving and supporting for drift in the powder ore was developed. taking the object of test stopes on induced caving roof which is based on the continuous mining method in the no. 92 ore of the tongkeng mine, based on the unloading rock mass mechanics theory, the calculation procedure is established to simulate and analyse the rock mass mechanical parameters under excavation unloading. based on mining, transportation, crushing and beneficiation links in sijiayingshan iron mine, the scheme and plan of reasonable ore supply and blending have been made by using objective function, in addition, measures taken included strengthening management, real-time monitor, the dynamic adjustment, to stabilize blending index for ore production. choosing nine factors of influencing the stability of surrounding rock and probing into the factors of the improved hierarchy gray clustering ore rock classification model are to improve the stability of the genesis of analytic hierarchy process, to determine each index synthesis weights, and application of grey clustering theory according to the stability of the final judgment. and applying them to the actual engineering practice of mining. according to china's economic and social development plans and the development of the coal industry planning, this paper introduces coal mining enterprise intelligent complete sets of equipment development present situation and developing trend and puts forward the fully mechanized coal complete sets of equipment of the key techniques of intelligent research, and the relevant technology research and innovation in system was put forward. after synthetically comparing the technical and economic indicators, security and environmental impact of the alternative development transportation system schemes, the design has adopted belt transportation in inclined shaft + trackless transportation in ramp, and analyzed the type selection and matching of transport equipments as well as the advanced control system of the selected equipment. this can bring the energy consumption of underground mining in chaishan mine of shzihuyuan to the Ⅰrate of the energy efficiency standard of nonferrous metals industry. see more images and information about Industrial Milling machines and used stamp mill sales prices and drawings ,visit this website:http://crusher.jawcrushermachinery.com/news/used-stamp-mill-sales-prices-and-drawings.html
