【摘要】：隨著鎢礦山的深部開采,各類地壓問題也不斷出現(xiàn),特別是作為高地應力條件下的巖石能量釋放方式之一的巖爆現(xiàn)象更為多見,巖爆傾向性預測評價是礦山安全的重要內(nèi)容。采用未確知測度理論與熵值法相結(jié)合的方法進行巖爆傾向性預測。根據(jù)巖爆傾向性的影響因素和分級標準,運用未確知測度理論建立了地下礦山巖爆傾向性預測評價指標的未確知測度函數(shù),用熵值法確定評價指標的權(quán)重,依據(jù)置信度識別模型對地下礦山巖爆傾向性預測進行評價,并結(jié)合實例進行了對比分析。研究結(jié)果表明,該方法為地下礦山巖爆傾向性預測評價提供了一種新方法。
[Abstract]:With the deep mining of tungsten mines, various kinds of earth pressure problems have appeared, especially the rock burst phenomenon, which is one of the ways of releasing rock energy under high ground stress, and the prediction and evaluation of rock burst tendency is an important part of mine safety. The unascertained measure theory and entropy method are used to predict the tendency of rock burst. According to the influencing factors and classification criteria of rockburst tendency, the unascertained measure function of prediction and evaluation index of rockburst tendency in underground mines is established by using unascertained measure theory, and the weight of evaluation index is determined by entropy method. The prediction of rockburst tendency in underground mines is evaluated based on the confidence recognition model, and a comparative analysis is carried out with an example. The results show that this method provides a new method for prediction and evaluation of rockburst tendency in underground mines.
