基于丁集矿13-1煤层的突出指标实测数据,建立了煤与瓦斯突出指标因子分析模型,提取出控制煤与瓦斯突出的3个公共因子:力学因子、煤的物性因子和瓦斯因子。经过丁集矿煤与瓦斯突出实际情况验证,得出:丁集矿采掘过程中煤与瓦斯突出的发生主要受地压影响较大,并且易发生以地应力为主的煤与瓦斯突出(压出)。 Based on the measured data of the prominent indicators of coal seam 13-1 in Dingji coal mine, a factor analysis model of coal and gas outburst index was established and three common factors controlling coal and gas outburst were extracted: mechanical factor, coal physical property factor and gas factor. Through the verification of Dingji coal and gas outburst, it is concluded that the occurrence of coal and gas outburst in Dingji coal mining process is mainly affected by ground pressure, and the occurrence of coal and gas outburst Out).
