Three-dimensional Modeling And Deep Mineral Prediction Based On Mining Geology

To seek for the resource replacement for crisis mine is becoming the hot issueabout the predictive assessment for mineral resources now. The crisis mine needs deepexploration and development and it is rich in the original material. Also the crisismine has the character that its direction of finding mine develops for deep and lateralplaces. Therefore, it demands of setting up the new theory of finding mine, the newtechnology and the new method which is acclimated to find crisis mine around thedeep and lateral areas. However, the3D metallogenic prediction is one of the effectivemethods for finding the hidden ore body which exists in the inner part of crisis mine.The3D metallogenic prediction is also the key point to solve the “crisis” of crisismine and it has an important significance to the resource replacement for crisis mine.This thesis is based on the scientific research funds project 《Application Modelfor Chemical Exploration of the Unknown Information Separation Technique in theProspecting Bases for Scientific Research》which is a non-profit behavior and thisproject is launched by the Ministry of Land and Resources. The author takesdelafossite from Tonglu Mountain in Hubei province as the research region. To thebasic data of exploration and production of mine, the author follows the systematiccollection and conclusion which are from the previous researchers and makes a“secondary development”. More specifically, the author follows the discipline ofgeological metallogenesis of ore-deposit and combines the poly nary mine realizationinformation with geological and chemical exploration. Besides, the author makes aquantitative study of the geological ore-control factors and it is based on the fullexploitation and analysis of the rich mine realization information and the use of themain geological ore-control factors. At the same time, for the previous geologicalwork, it usually projects the stratum, structure, physiognomy and ore-body in spaceonto a surface. Then the researchers analyze them through the2D and section drawing.However, it will reduce the credibility of prediction inevitably. In this thesis, theauthor bases on the3D geologic model of the whole mining area which vividlyreflects the geologic structure, the directional distribution of metallogenic factors andthe character of directional distribution of the chemical properties about geologicalbody. In this thesis, the author uses the FAHP to have the metallogenic prognosis andconstructs the3D ore-prospecting model. Also the author wants to realize the locatingprediction of blind ore body and systematically analyze the ore body target zone ofprediction within the research region. The known ore body and engineering validation results show that the method is effectual and indicate that it is an effectual way tolaunch the3D prediction of prospecting target zone in the inner part of known mine.
