| At present, the heat disaster of the deep ore has new difficult problems, which had restricted the development of the mining industry in our country. The thesis has carried works on recongnasing,analysicing and the safety evaluating to sources of heat disaster with the theory of systematic analysis and the principle of cognization of dangerous sources.First, using the theory of the path overlapping and the theory of accident, the thesis has determinated and analysiced the distribution condition of sources of heat , and carries on recognizing the dangerous sources of heat disaster. Then, on the basic of the systems engineering ,by using the method of the work condition risky analytic,the theory of fuzzy mathematics , analysiced and appraisaled works have been done for the present internal heat environment in mine and the present temperature decrease system. Finally, research has carried on the qualitative computation, using the accident tree analytic method to the coal internal heat disaster, obtained the primary factors that caused the heat disaster.By utilizing VC++, the decision-making support program of mine heat disaster appraisal has been developed , which can cut down calculate amounts by hand and especially make calculation accurate togetherConcreting 343 mining area heat harms condition , has carried out identification of harms dangerous source and valuation specifically for Fu Xin City company (Corp.) of mining industry Qing He Men coal mine.According to the result that all above analyses,and the concrete conditions of Qing He Men coal mine , has suggestted that hot evil governs measure. |
