摘　　要：斯派尔煤矿属于高瓦斯矿井,受复杂地质构造条件的影响,容易发生瓦斯动力现象。通过对现场测试数据分析,选择了反映掘进工作面瓦斯涌出特征的指标作为瓦斯动力现象监测的主要指标,并利用控制图方法和3σ原理确定了各监测指标的预警临界值;最终形成了适合现场实际的监测及预警技术,对于实现斯派尔矿瓦斯动力现象的准确预测具有重要的意义。Sipaier coalmine belongs to high gas mine, with complicated geological structure conditions, easily leading to gas dynamic phenomenon. Ac- cording to the analysis of the field testing data, the key monitoring indexes of gas dynamic phenomenon that reflected gas emission characteristics of the tunneling working face, are selected. The warning critical value of monitoring indexes is determined by using the control chart method and the three - Sig- ma principle. Finally the monitoring and early warning technology for field is formed and is significant for the accurate prediction of gas dynamic phenome- non in Sipaier coalmine.
