摘　　要：确定煤层突出区域预测指标瓦斯含量临界值的大小对于保障矿井安全生产和降低防突成本具有重要意义,而瓦斯含量临界值的确定方法是否恰当直接关系到临界值确定的准确性。结合车集煤矿实际,提出了通过历史资料统计分析、现场参数补充测试及跟踪考察、实验室模拟测试、瓦斯含量临界值对比分析、模拟计算及应用效果检验等相结合的方法来共同确定瓦斯含量临界值。由该方法确定的瓦斯含量临界值应用效果良好,具有普遍的推广价值。Determining the critical value of the gas content prediction index in the coal seam outburst area has an important means for safety production in coal mine and which can reduce the cost of outburst prevention,the determine method of gas content critical value whether it is appropriate is directly related to the accuracy of gas content critical value. Combined with the practical of Juji coal mine,by statistical analysis of historical data,field parameters supplementary testing and tracking investigation,laboratory simulation tests,comparing the gas content critical value of different coal mines,simulation and effect inspection,such as a combination of methods to jointly determine the gas content critical value ware presented. The gas content critical value determined by this method ware applied to good results,and has broad promotional values.
