矿井动力现象预测的准确性和可靠性，从根本上说取决于对区域构造应力场和活动断裂的研究水平，文中利用趋势面分析方法．确定了平顶山十矿井田内的一条活动断裂（Ⅲ-12间断裂），得出Ⅲ-12断裂对其所影响范围内的瓦斯突出发生具有控制作用、从时间上和空间上制约着平顶山十矿煤与瓦斯突出发生的结论。 The accuracy and reliability of the prediction of mine dynamic phenomena depend fundamentally on the level of research on the stress field and active faults in the regional tectonics. In this paper, the trend surface analysis method is used. An active fault (Ⅲ-12 fractures) in Pingdingshan No.10 coal mine field was determined. It was concluded that Ⅲ-12 fault had a controlling effect on the occurrence of gas outburst in the area affected by it, and controlled the time and space constraints of Pingdingshan ten- Concluded with gas outburst.
