Three-dimensional Modelingon Exploitation Of Gold Deposit In Getang And Its Analysis Of Stability

Carlin-type gold deposit belongs to fine disseminated gold deposit, because of the prevalence of such deposit gold deposit in complex form, ore and rock boundaries is not obvious features, so there are many problems in the process of exploitation from this type of gold mine.The result of this type of gold resources is difficult and efficient development and utilization.Getang gold mine as a typical fine disseminated deposit, we are facing common problems in the process of mining of gold deposits.Such as mining loss and dilution is difficult to control, low efficiency of mining, underground pressure is difficult to control and other issues.Getang fine disseminated gold deposits, also known as complex and difficult mining gold mine, its complexity mainly in the state complex ore body, roof stability is poor, considerable variation regularity bottom poor, mining loss and dilution is difficult to control. Leading to the border demarcation gold mines is difficult, difficult to control mining pressure control, low mining efficiency, to mine management and efficient exploitation has brought great difficulties.In this paper, State The Twelfth Five-year Science and Technology Support Project(2012BAB08B00),The Study and Demonstrationon Technology of Green Mining, Mineral, Smelting of Large Gold Minea subject research(2012BAB08B06), relying on Finely disseminated refractory gold ore mining and efficient development and utilization of key technology research According to Anlong Getang Gold Deposit complex morphology and geological conditions, rock stability analysis by using 3DMine, FLAC3 D, RFPA and other three-dimensional modeling software:(1) Geological data mining through 3DMine engineering software, the establishment of a geological model of the study area, this can be very intuitive, clear text presented geological, mining model to facilitate the next step of mines, and then establish and analysethe model of surrounding rock stability.(2) By analyzing the geological model, combining data mining drill, drill set up a database for further analysis orebody morphology, occurrence, the exploitation of mines show in the 3D model, a three-dimensional model of mine exploitation.(3) By analyzing the three-dimensional geological model and three-dimensional drilling model, model, further analysis under mining disturbances, stability of surrounding rock.Through these studies, the ultimate goal is to solve some practical problems of mine. To improve the recovery efficiency of mines, pressure from mines to provide effective control of important reference.
