龙滩煤矿突出预测敏感指标及临界值研究

Study on Sensitive Index and Critical Value of Outburst Prediction in Longtan Coal Mine

突出预测指标敏感性分析及临界值的确定是突出预测的关键,以龙滩煤矿突出煤层工作面为背景,通过实验室研究及现场实测相结合的方法,总结得出适合矿井自身特点的敏感指标和临界值,提高突出预测准确率,防止出现低指标突出、高指标不突的现象,确保矿井安全生产。

The sensitivity analysis of outburst prediction index and the determination of critical value are the key to outburst prediction. Based on the working face of outburst coal seam in Longtan coal mine, through the combination of laboratory research and field measurement, summarizes the sensitive index and critical value suitable for mine own characteristics, improves the accuracy of outburst prediction, prevents the phenomenon of low index outburst and high index non-outburst, and ensures the safety of mine production.
