A Study On The Mine Environmental Management Performance Evaluation And Prediction

Mineral resource is an important part of natural resources, but also the foundation of human survival and development, related to the lifeline of national economic and social development. Although our country enjoys a multiple types of mineral resource, but the pillar type mineral resources is in seriously shortage, distribution and reserves is not ideal. After decades of large-scale, high strength of the resources exploitation, the contradiction between supply and demand and ecological problems become two big bottlenecks which restricted the economic development of our country. The current mineral resources development and utilization process exist certain kind of blindness and myopia.In the departed development, laggard technological level, huge destruction waste, low recovery ratio, plus inappropriate system, instable market, poor management efficiency, the over cost of resources and the environment. The mine environment question and in the node, make the fragile ecological environment system under very severe pressure, pose a great threat to the sustainable development of national economy. Therefore, protection of the mine environment, reasonable development and utilization of the resources, promote the harmonious development of mining cities is a long-term and arduous task.With the advent of the knowledge economy and the globalization era, the contradiction between rapid economic growth and resource, environment keep growing, the international society has paid more and more attention in the role of enterprises from other countries to coordinate economic, social and environmental aspects. The general experience of foreign mine environmental protection in developed countries, its success lies in mine environment management been put in place, in order to prevent in advance instead of the passive management, and in this block it’s what we defected. Compared with the international level, China’s mine environment management in theory research and practice there is a considerable distance; mine environment management system research and practice in the great lag behind the demand of development of mining industry. Performance evaluation, especially environmental performance (also called the green performance) evaluation, has become a common topic. With the continuous development of enterprise performance, the traditional experience and subjective performance evaluation method is not adapt to the needs of work, among them, the environmental performance quantitative, accurate assessment of the demand is higher and higher, technology and quantitative methods has become more and more popular. Although our country these years about enterprise performance evaluation research both in the depth and in span all some development, but for mine enterprise’s environmental performance evaluation and prediction research is still in a relatively scattered state. Therefore, to strengthen the related theoretical study and practical exploration in China to change the mine environment management situation is very meaningful.This paper mainly tries to solve two key problems:first, because of mine environment management performance theory which including enterprise performance theory, mining management theory, sustainable development theory etc, and the current performance of quantitative, accurate assessment of the demand is higher and higher, technology, quantitative method become particularly necessary. Establish a scientific mine environment management performance evaluation index system and index selection even modeling problem need to be solved urgently. Second, in the choice of research method, practice is the only way to inspection. In this paper we combined the theoretical and empirical, through empirical to verify aforesaid mine environment management performance evaluation method to examine and improve its function, so that the method is scientific, generality and applicability, this is also another key problems need to be solved. Based on the above reasons, this paper deeply analyzes the present situation of the mine management, aiming at mine environment management performance, and also discusses the mine environment management of the performance evaluation of technology and method, guided by the scientific development concept, according to mine environment problems of the characteristics, types, combined with the mining before, in and shut the ore phase to the mine environment question management factor to carry on the analysis, the establishment of a mine environment management performance evaluation index system, and design the evaluation and prediction model and method.In the empirical analysis, based on the mine data, for example, to verify mine environment management performance evaluation and prediction methods, make its have generality, comprehensive, orientation, scientific, flexibility, adaptability theses six major characteristics, and find the mine environment problems existing in the management, which verify the applicability of the performance evaluation and prediction method.Full text is divided into eight chapters, mainly including theory and method, quantitative and countermeasures study three parts.This paper firstly introduces background significance of the research, and puts forward the research methods, technical route and innovation points. Consider that our country’s enterprise performance appraisal theory research starts relatively late, the present research mainly limited to the introduction and evaluation of the foreign performance evaluation theory, the practice summary and the refining for domestic enterprise performance evaluation is not enough. The deficiency of mine environment management performance exist in most of the literature, also have no a clear explanation, just discussions about the specific operation of the surface problems, and at the same time, domestic mine environment management performance evaluation system also has not been formed. Therefore, this thesis topic has great significance in both theoretical and practical ways.The following part is the elaboration of the theory and research method. The second chapter is the theory research. On the one hand may learn from the lack of current theory of the present research situation in order to point out the mine enterprise’s environmental performance evaluation and prediction of the research significance, has been clear about the thesis research value and direction; On the other hand, the existing research theory analysis and control for the development of the research work provides an important theoretical guidance. First of all, combed the related concepts for the performance, performance evaluation, expounds the origin and development of the theory of performance in detail. The deficiency of mine environment management performance exist in most of the literature, also have no a clear explanation, just discussions about the specific operation of the surface sexual problems. Through the performance theory research, defines the concept of performance evaluation in this research paper at the same time. Secondly, this paper expounds the sustainable development theory, the circulation economic theory, ecological industry based on the theory of mineral resources exploitation and environmental protection phase harmonious development from concept, mode, target three direction was also in mine environment management performance in guiding ideology provides the theory support. The third chapter is mine environment management performance evaluation and forecasting method choice of part, first to tradition and the development of the evaluation and prediction method is introduced. For mine environment management performance this evaluation, is based on expert ability, instructions, preference, experience above, this evaluation with certain fuzziness and uncertainty (gray sex), in order to reduce error using high resolution, high precision, simple application of grey theory is more appropriate. For mine environment management performance forecast the piece, data collecting and processing is very important, need a lot of arrangement and calculation work. MATLAB toolbox, and the introduction of the rough set theory, greatly simplifying the workload in the exclusion of will interference prediction results contain redundant information redundant indexes, leave the outcome in the most obvious impact index, then after reduction of the index data as the input samples the prediction of future performance. And finally verify such combination model’s superiority towards the single neural network model. Through the analysis of grey comprehensive evaluation method and rough set artificial neural network method and also considered about their advantages and disadvantages of feasibility, ultimately choose the grey comprehensive evaluation method as mine environment management performance evaluation method; Using rough set artificial neural network combination method as mine environment management performance prediction method.Quantitative study part is the core of this article, mainly formed by chapter four, chapter five and chapter six. The fourth chapter firstly summarizes the mine environment problems, management mode and current situation. Believe that the domestic mine environment research, prevention and control level is relatively low, mining enterprises will easily cause soil and water loss in the development and utilization of resources process, induce geological disasters. Then, it gave us a summary on the mine environment management performance. Emphasis on the environment management main body should be diversified, namely the government as the guide, the enterprise as the core and implement, the public to participate is the tripartite main form. Then in the mine environment management performance evaluation system construction part this paper points out that mine environmental governance performance will be combined with mining early and middle, shut the ore phase respectively from the business performance and financial performance, benefit performance evaluation and analysis of the three aspects, and with fuzzy APH method to establish index weight to hierarchy grey comprehensive evaluation method as mine environment management performance evaluation method to evaluate the objects by evaluation. The fifth chapter expounds the mine environment management performance prediction method and procedure, has established good index system, through the rough sets theory of attribute reduction method, reduction the evaluation index number, again through the neural network prediction of performance analysis. At last, chapter six by means of the empirical manner to precede the mine environment management performance evaluation and forecast evaluation based on the first two chapters’study method. Then analyze its data, charts, and results, draw the corresponding conclusion. Finally come up with a comparative analysis of the mine environment management performance evaluation method and the forecast method, the author summarizes the advantages and disadvantages of them, the same differences, as well as the suitability of generalization.In the countermeasures study part, the upgrading advices for our mine environment management performance have been put forward. Mine environment management is an important part of the mine environment; protect the mine geological environment, to improve the ecological environment have significance meanings of promoting sustainable economic and social development. Mine environment management performance evaluation is the inspection of mine environment management work. Emphasis on the environment management main body should be diversified, namely the government as the guide, the enterprise as the core and implement, the public to participate is the tripartite main form. From the government level, is need to establish unified relevant policy guidance and laws and regulations, build mine management performance participating supervision environment. From the enterprise level, is to positively construct the system of enterprise performance evaluation theory framework, such as scientific selection of suitable performance index evaluation method, promoting performance evaluation institutionalization, research and popularize the typical enterprise performance evaluation index system, perfecting the scientific performance evaluation index system, From the public level, strengthen environmental consciousness and to participate in environmental protection is particularly important.After the conclusions and summarizations of whole research, writer put forward the prospect of research at last. Because of mine environment management is a complex and huge industrial system, involves the multiple research problems, this paper’s focuses and coverage is limited, in the future, the author aim to not only improve and strengthen in the research of the theory, method but also the depth aspects in the future research. The innovation of this paper lies in:(1) Based on the analysis of the performance evaluation theory, the rough set theory, the neural network theory, sustainable development theory, this paper systematically chose the mine management performance evaluation and prediction method, built up a mine environment management performance evaluation index system, established the corresponding index and its weight, and structured the comprehensive evaluation based on grey evaluation model,(2) Combined attribute reduction method of the rough set theory and the neural network model in order to construct the mine environment management performance forecast model, improve the mine management performance evaluation and prediction methods at the same time.(3) Using the empirical method, test the applicability of the evaluation index. Through the combination of theory and empirical research in order to form scientific and practical mine environment management performance evaluation and forecasting method, and promote the effective governance of the mine environment.
