| The paper selected topic with the research projects of "lead-zinc ore resource potential evaluation and law of prospecting at Sichuan-Yunnan-Guizhou border region". Identified a variety of ore deposit value with the variation factors and their combinations, and established the functional relationship between ore-controlling factors and the value of deposit by studying the geological features of the area, such as regional geological setting, geological characteristics of ore district, geochemistry, lithofacies palaeogeography, remote sensing image characteristics. According to the regional ore-controlling factors and prospecting between the amount of resources in a way and there are some inherent between the statistical relationship, select a certain model element, the use of regression analysis for statistical analysis, looking for ore-controlling factors and The integrated value of the mine signs-information and resources as a function, and thus a quantitative study area resource estimate.Paper received the following understanding:1. A systematic analysis of Yiliang-Zhenxiong lead-zinc mine ore-concentrated areas deposits (points) the space distribution features of concentration area lead-zinc mine (points) mainly along the north west Yadu-Mangdong homozygous fracture and north east to Taurus factory-mine factory, five-star factory-impressive fracture distribution, car newsletter ne-trending faults and north west to structure and other ore-controlling factors combined control of the zinc mineral distribution.2. In Yiliang-zhenxiong lead-zinc mine ore-concentrated areas lines ring structure of remote sensing images based on the interpretation that the qualitative analysis of remote sensing information to identify the dominant factor controlling distribution of ore deposits, while the linear structure of quantitative remote sensing analysis, can be analyzed to determine the location of ore a number of quantitative spatial characteristics, and thus deepen the ore mining and ore-controlling factors in understanding of the law.3. According to deposit distribution and fracture beam (fold bundle), as well as contains the ore formation, relationship between choice concentrated mineralization zone is representative of the typical ore deposits:MaoPing lead-zinc mine, Luozehe lead-zinc mine to dissect research, developed elements map of a typical deposit, typical ore deposits forecast map elements and formulate typical ore deposits prediction research elements chart and prediction model diagrams.4. Established Yiliang-Zhenxiong lead-zinc mine ore-concentrated areas mineralization geological spatial data, the multivariate ground, geochemical and remote-sensing information organic combine, ore-controlling factors and prospecting marks the determination, plays in an important role.5. The research presented to the constructor and the North East, North West, to construct a common ore;6. Determined the research area forecast target area and carries out quantitative forecast to the amount of resource, ore-concentrated areas have proven recoverable resource for 698,000 tons, forecast lower 841,000 tons, forecast for the upper limit of amount 1621,920 tons. |
