摘要
针对矿井"低指标突出"频发的现象,从预测指标的选择和临界值的确定两个方面进行分析,建立数学模型,确定敏感指标和临界值。为不同条件下突出矿井的敏感指标选择和临界值的确定提供一种较为简便的方法。
Based on low-index outburst frequently occurred in coal,this paper analyze this phenomenon from two aspects：selection of prediction index and critical value determination.Then establish mathematical model and determine sensitive index and critical value.This paper provide a easier method for determine sensitive index and critical value in different conditions outburst coals.
