Researchs On Assessment And Early Warning System System Of Geotechnical Engineering Environment For Typical Metal Mine

With the exploitation of Metal Mining, the negative impacts were generated and widespread increasinggly, it not only caused economic loss and casualties, but also e-nabled the mining area degradation in geotechnical engineering environmental, land and water resources are subject to different degrees of damage.In the current, the progress of geotechnical engineering environmental studying for metal mine is slower. With the constant development of chinese industries, the demanding for metals continued to increase,which accelerating the pace of metal mining exploitation, the geotechnical engineering environmental problems have seriously affected the mine's construction and development, The Geotechnical Engineering environmental issues should be treated. The impact factors of Metal mine geotechnical engineering environmenttal is various, and the geotechnical evaluation of the environment is also very complicated. With the variety of evaluation methods and theories are constantly emerging, which provides convenient platform for geotechnical engineering of metal mine. However, these methods or theories only against one aspects of geotechnical engineering. d-eal with the problem of multiple factors for the environmental evaluation, which could be onesided and limit, can not reflect the overall mine geotechnical environment,in addition, evaluation of the accuracy also can not meet the requirements. So the comprehensive evaluation studying of geotechnical engineering environment for metal mining is of great significance.In order to evaluate the metal mine geotechnical mining environment on the dangers of mining and suitability of land for construction purposes correctly, the paper works on the basis properties in mining conditions of the metal mine geotechnical engineering which analysis major environmental factors, Identify mechanism that forming. Through investigating the Guangxi typical metal mine geotechnical engineering environmental situation, statist and analysis the major factors which affect the general law and the impact of the mine ,start the actual research, collect mine geotechnical e-ngineering environmental factors which affect the historical information and the actual data of potential impact, from metal mine geotechnical engineering works of various environmental factors, use the methods of field test to analysis, establish the specific impact and comprehensive evaluation model of metal mine, evaluat impacts of m-etal mines in all levels, That is to evaluat geotechnical engineering respectively according to geological conditions under the environment, hydrogeological conditions, e- nvironmental geological conditions, then to the one treatment, focus on the evaluation that results will be more comprehensive and objective. finally establish geotechnical engineering environment evaluation system of metal mine with analysising method a-nd variety theories,through applying in the Guangxi typical metal mine geotechnical engineering environment, according to the actual mine evaluation results, develop the optimal prevention and control measures.In this paper, with AHP and fuzzy math theory, mathematical theory and associated grey theory to establish MTC comprehensive evaluation system which aim for c-omprehensive assessment of metal mines geotechnical engineering environment, and evaluat typical mines, mine geotechnical engineering environment will be divided into four levels comprehensive evaluation. which is appropriate, suitable for basic, suitability poor and no appropriation a, evaluation results show that the MTC evaluation system not only has uniformity system, which may apply to the appropriate evaluation of the metal mine geotechnical environment, but also provide a scientific basis data and technical feasibility for metal mines geotechnical engineering which are of implementation and governance for environment. MTC comprehensive environmental evaluation system which establish with more theory of metal mine geotechnical engineering environment, and apply in the typical metal mine geotechnical engineering e-nvironment,the results that made with the actual situation is identical. Thus, MTC evaluation system to assess of the system has a very wide range of applications. Geotechnical engineeering environmental impacts have unexpected factors and more frequency, so establish geotechnical engineering environmental early warning system may prevent unexpected incidents,In this paper, according to the identity of geotechnical engineering environmental impact factors , establish a early warning system model with MATLAB calculation software for metal mine geotechnical engineering enviro-nment.The model applied in the typical metal mine, and achieved good results.
