Research On The Digitization Evaluation Technology In Deposit Mining Environment

The digitization model of deposit mining environment is the foundation of the digital mine construction, we can not provide the basal platform that deciding the design development and system movement of communication system, production scheduling, personnel equipment orientation, production process safe monitoring, warning system, and production process virtual reality system following the digital mine construction, for digital mine construction unless we have completely grasped the condition of deposit mining environment.The deposit mining environment digitization valuation mainly adopt the technology of irregular triangular net to produce the digital terrain surface model and the 3d geological solid model, including orebody, rock and fault, simultaneously uses the changing block technology to establish deposit resources appraisal block model. Finally, carrying on the block model estimates by geology statistical theory obtains the tenor spatial distribution of complex geologic model both in conformation and randomicity as well as synthesis appraisal technology production about mining environment, and carries on mining scheme optimization and design in this foundation.In this paper, the No.3 district of Jinchuan corporation is the research object. The 3d geological solid model and block model with tenor distribution had been established by dint of the large mining software, and rock constitution, physics mechanical properties of ore rock and discontinuity surface had been analyzed and appraised. In this foundation, the caveability classification judgment index system of ore body had been researched, according to the computation and statistic about judgment index, study variogram function model, the 3d appraisal model with judgment index had been established as well as the caveability 3d classification model of ore body had been established by fuzziness classification technology. Finally, the caveability classification, subarea and synthesis appraisal of the No.3 district had been carried on. The theory and method stated by this paper has very strong pertinence and applicability in the deposit mining environment appraisal. The result indicate that the digitized techology is highly effective reasonable in the deposit mining environment appraisal. It will also play a huge impetus role in our country mine enterprise's digitized advancement and have the significance both in theory and practice.
