The Research On The Dynamic Management Of Reserves In Dabaoshan Polymetallic Mining Areas

With the continuous exploitation of China’s mineral resources,the mining technology has kept pace with the new generation,and the reserves of mineral resources have been changing.Traditional static reserves management has been unable to keep up with the current pace of mining.At the same time,the rapid development of technology has promoted the construction of digital mines.Therefore,there is an urgent need to conduct theoretical and practical research on the dynamic management of polymetallic deposits to serve the management of mine reserves.In this paper,we use 3D digital mining software as the basic tool to study the dynamic management of Dabao Mountain polymetallic deposit reserves,taking into account the resource endowment conditions of Dabao Mountain polymetallic mine area.Firstly,digital modeling of the polymetallic ore area is carried out to form a block model of the ore area and a mining grade model of the ore body.Secondly,based on the established 3D digital model,the construction of mining and stripping plan scheduling and ore allocation plan scheduling modules was carried out.Again,using the resource mining process data,the actual production and mining results are compared with the planning model to track the dynamic changes of reserves.Finally,based on the mineral resource information management system,the database of mineral resource management system and 3D visualization and analysis technology are used to realize the refined dynamic information management of resource,reserve level,tertiary mineral volume and three rate indicators in the whole process of mineral resource exploration and development.The main research results of this thesis are as follows.1)Construct a digital model of resource reserves based on digital model technology.Using the model,carry out reserve calculation and update.By analyzing the changes of resource reserves in the process of geological exploration and resource exploitation,timely dynamic adjustment is made.2)Establish a comprehensive management system for mineral resources by analyzing basic geological work,mineral resources reserves and geological data.The corresponding management mechanism is proposed to make the mineral resources management work institutionalized,standardized,templated and informationized.3)By analyzing the quality of mineral resources and improving the classification of mineral resources,it provides effective information on the availability and reliability of retained resources reserves,prospecting prospects,mining technology conditions,external development environment,etc.for the decision-making level of mines,and provides powerful reference for the mining development planning and long-term development of mines.Figure 104,table 6,and reference 71.
