The Research And Realization Of Mineral Resources And Reserves Dynamic Calculation Module Based On MapGIS

At present, there are instances that MapGIS is lack of mature reserve calculation module with simple operation, foreign reserves estimation software is expensive with complex operation and calculation and the constraints exist on the aspects of technical conditions and capacity of the staff in mine. So in order to meet the needs of market, the mine actual production requirements, and the demands of dynamic supervision and management on mining reserves by Ministry of Land Resource, the paper has researched the key technologies about dynamic calculation on mineral resources reserves based on the analysis of the space and time characteristics on mineral resources through consulting literature. And by simplifying procedure model, the paper has proposed a technical solution about dynamic calculation module on mineral resources reserves.Based on market economy pattern and GIS technology, the paper has developed a dynamic calculation module on mineral resources reserves with.Net development platform, by taking MapGIS as the development tool and C#as the development language. The developed module is able to analysis and monitor mineral resources reserves dynamically both in space and time with easy operation, which in line with the actual needs in mine production. Also, the module has achieved many functions such as the rapid and mutual delineation of the ore body, automatic drawing and output on geologic section maps, rapid calculation and dynamic analysis on the mine reserves, dynamic adjustment of industrial indicators (the cutoff grade), dynamic output on reserves reporting and statistical analysis chart, interactive display on graph and attribute. Those functions have improved the working efficiency and the level of management greatly in respect of geological data processing and the resource reserves estimation, which increases the economic benefits of the mine.Based on the project of "Metallogenic regularity and prediction of Zhijiadi Pb-Zn-Ag deposit in Lingqiu, Shanxi" approved by National crisis mine exploration project management office, the developed module has been integrated to the data management system of Zhijiadi Pb-Zn-Ag deposit. And this module has also been verified by the actual geological data in ZhiJiaDi district, and the results show that the module can not only satisfy the mine’s actual request, but also can reach the anticipation purpose.
