摘要
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 coal and gas outburst indicators measured data of Dingji 13 -1 coal seam, factor analysis and evaluation model for coal and gas outburst was set up. Three public factors of coal and gas outburst in Dingji Coal Mine were proposed; they were mechanical factor, the physical properties of coal and gas factor. With the actual situation of coal and gas outburst in Dingji Coal Mine, the results show that coal and gas outburst was mainly affected by the ground pressure and was prone to coal and gas outburst （extrusion） with geostress.
