Reasonable Exploration And Exploitation About Mineral Resource And Sustainable Development Of Mining Industry

As geologists, usually we thought mining only depends on geological factor, but actually there are several factors influencing the mining development. Interdiscipline research plays an important role in sustainable development of the mining industry. We put forward a solid mineral resource model about 'double control' and '5R economy' theory for mining. The concept of 'double control' theory and reasonable area in mineral exploration and exploitation modeling is presented. 'Double control' includes two controlling factors, namely the degree of geological study and the economic study. Geological research combined with economic analyses is crucial to the evaluation of mineral resources. The application of this model is tested in mineral exploration and exploitation, which would make the exploration and exploitation smoothly and economically. Based on 3R Recycling Economy Theory, We developed the '5R' Recycling Economy Theory which is composed of Rediscovery, Reduce, Reuse, Recycle and Reclamation. These theories will promote the development of mining industry.Efficient exploration and exploitation of mineral resources plays an important role in sustainable development of the mining industry. With the objective of improving living standards world-wide, demand for solid mineral resources probably will continue to increase for the foreseeable future. Many of the large-super large, high grade, close to surface and close to market mineral deposits have been depleted or are currently in production. More and larger deposits have to be discovered to meet increased demand for mineral commodities. Over the past several years, the demand of base-metals increased significantly in China. The output also increased. According to data, there is an emergent need for iron ore and aluminum in China. Mining plays a backbone role in China's national economy. At present, the mining sector is providing 93% of energy, 80% of raw materials for industry and 70% of means of production for agriculture. The sustainable development of the mining industry is an increasingly important problem facing the sector. Our ability to meet the continuing and growing demand for minerals is greatly affected by concerns about reasonable exploration and exploitation of mineral resources. The purpose of this paper is to present a conceptual model about reasonable exploration and exploitation of solid mineral resources.The simplified model is divided into a series of stages. Efficient exploration and exploitation of mineral resources is highly dependent on the quality control exercised at each stage of the process. At each step in the resource modeling process it is necessary to define the specific objectives, the methodology proposed to achieve those objectives and to establish a set of validation tools to assess the outcome. Resource estimation is a complex process involving different specialists with relevant experience using a multidisciplinary approach. We propose that the double control theory, which comprises geological and economic factors, is an effective management tool. Geological quality is a function of deposit grade, deposit size, and 'other' geological factors. Mineral deposits of the same deposit type have similar geological quality attributes. Economic quality is measured relative to a benchmark. As geologists we must understand the economic impact of our plays and prospects. Geological analyses and economic analyses are crucial to the evaluation of resource. The resource classifications are directly related to the appraisal stages of the project. For an inferred resource, geological and grade continuity are assumed, but not established. At the inferred category, scoping-stage evaluations can be carried out to determine if further exploration or technical investigations are warranted. At the indicated category, geological and grade continuity have been reasonably established, but short-range grade variability is not well known. The information is sufficient to carry out pre-feasibility stage assessments and assess the economic viability of the deposit. At the measured category, the geological continuity of the deposit and the local grade continuity including short-range variability have been established with a high degree of confidence.Models of the process of reasonable exploitation of mineral resources are illustrated. We divide exploitation process into seven stages. These comprise trial-production stage, development stage, production steady stage, production decline stage, supplementary exploration stage, closure of mine stage, and reclamation stage.In order to test the model, a total of 52 iron deposits, both economic and uneconomic, were studied According to data of 52 iron mines, we contrast mine design capacity with actual mine capacity and design mine life with actual mine life.Through contrasting mine design data with actual data we get the result of exploration with the result of exploitation and reflect it graphically. On the graph a "blue" point represents a good-quality deposit, while a "red" point falls short of that quality. Based on the above analysis, we get 24 good quality deposits (including 8 large size, 14 medium size, and 2 small size), we will input the geological factors and economic factors into assessment software as study sample then we input factors about the rest of the deposits into assessment software to obtain results.Mineral deposits are the products of various geological processes. The most common measure of geological quality is recoverable ore reserve tonnage and grade. Mineral deposits of the same deposit type have similar geological quality attributes. The key geological quality features of deposit types have been considered. Economic quality is a relative benchmark. The benchmark relevant to the present study is exploration success measured by the net present value. The higher the Net Present Value the better the quality of the deposit. Geological condition is complex in China, there are so many type of deposit. Part of those deposits cannot be exploited, due to their processing and metallurgy characteristics, exploitation technology and disadvantage traffic condition and climate condition ore carry cost too high or climate is too bad. In the above discussion, we obtain a curve about reasonable exploration & exploitation, our study is still going on. We need to research more commodities and more deposits. We will test this model further and revise it.
