【摘要】：為準(zhǔn)確反映礦井事故發(fā)生的跳變過程,并對礦井安全狀態(tài)作出客觀評價,構(gòu)建煤礦安全狀態(tài)的突變評價模型。首先,以辯證唯物主義、軌跡交叉理論及突變原理為指導(dǎo),構(gòu)建煤礦安全狀態(tài)評價指標(biāo)體系;其次,對底層指標(biāo)參數(shù)進(jìn)行無量綱處理;然后,根據(jù)不同突變類型歸一化公式及突變評價規(guī)則,借助Matlab逐級求得突變隸屬函數(shù)值,參照安全狀態(tài)等級評價標(biāo)準(zhǔn)確定安全狀態(tài)級別;最后以11個礦井?dāng)?shù)據(jù)為樣本進(jìn)行安全狀態(tài)評價,并將計算結(jié)果與模糊可變識別評價結(jié)果進(jìn)行比較。結(jié)果顯示,2種模型評價結(jié)果總體保持一致,突變評價模型指標(biāo)計算值與近年煤礦安全事故發(fā)生原因統(tǒng)計分析結(jié)果更貼近。
[Abstract]:In order to accurately reflect the jump process of mine accidents and make an objective evaluation of mine safety status, a catastrophe evaluation model of coal mine safety state is constructed. Firstly, under the guidance of dialectical materialism, trajectory crossover theory and catastrophe principle, the evaluation index system of coal mine safety state is constructed. Secondly, the dimensionless treatment of the bottom index parameters is carried out. According to the normalization formula of different mutation types and the rules of catastrophe evaluation, the membership function value of mutation is obtained by means of Matlab step by step, and the safety state level is determined by referring to the evaluation standard of safety state grade. Finally, 11 mine data are taken as samples to evaluate the safety state, and the calculated results are compared with the results of fuzzy variable recognition evaluation. The results show that the evaluation results of the two models are consistent, and the calculated values of the catastrophe evaluation models are closer to the statistical analysis results of the causes of coal mine safety accidents in recent years.
