The Study Of Evaluation Of Geographical Disaster In Metal Mine

Geological disasters of metal mine is influenced by a lot of factors such as human activity, climate, vegetation, landform, terrain, condition and the scale, frequency, density, of historical calamity etc. Since geological disasters of different scope required precision of assessment is diversity and indication of element factor of activity degree of geological disasters is diversity, mine assessment has a lot of different contents and means and the research to proceeds valuation method to mine has a great of meaning. In order to correct appraising the risk and destruction of mine, this subject, through actual investigating into metal mine, collecting much data which is about the historical calamity and laten disastets, which basiced on analysing the base attribute of geological disasters established the model of risk synthesized assessment and divided the risk of metal mine into four grades which are stability second stability dangerous very dangerous, which used the level of analytical method to proceeds with fuzzing mathematics principle to synthesize analysised the kinds of factors of oking geological disasters; this subject, through appraising the distruction of mine, established distructive model which used probabilistic method and divided the loss degree of disaster and the loss degree of life into low, middle, high three grades; this subject, through appraising the risk synthesized assessment and distructive model of twenty-four valuation areas, selected optimum prophylactico-therapeutic measures according to actual appraisal result of every mine.The using model analysed and appraised mine not only expressed the level of analytical method, the fuzzing mathematics of analytical method and the probability of analytical method to be applicable to the safety valuating of metals mine, but also provided scientific basic and technique feasibility for preventing and managing the geological disasters of metal mine. This it can be seen that, the level of analytical method, the fuzzing mathematics of analytical method, the probability of analytical method have very extensive apply value in system assessment.
