基于深部煤与瓦斯突出全过程的热−流−固耦合规律，建立了煤与瓦斯突出数值模型，分析了深部高应力条件下突出全过程中多物理场参数响应。研究结果表明：突出孔洞周围煤岩体应力场的响应规律为初始振动−突然衰减−后期稳定；瓦斯压力的下降速率与距离突出口的长度呈负相关关系；突出过程中，破碎煤所包含的吸附瓦斯迅速解吸并且膨胀做功，导致温度降低；突出发生后，渗透率发生显著变化的区域可分为突增区、中等增长区和增长区；随着应力的增加，弹性潜能占煤与瓦斯突出总能量的比例不断增加，弹性潜能占比与应力呈正相关关系。

Based on the thermo-fluid-solid coupling law of coal and gas outburst in deep mining, a numerical model of coal and gas outburst is established, and the response of multi-physical parameters in the whole process of coal and gas outburst under high stress condition is analyzed. The results show that the response rule of the stress field around the outburst hole is initial vibration-sudden attenuation-late stability. The decreasing rate of gas pressure is negatively correlated with the length of the outburst hole. In the outburst process, the adsorbed gas contained in the crushed coal quickly desorbed and expanded to do work, resulting in a decrease in temperature; the areas with significant changes in permeability after outburst can be divided into sudden increase area, medium increase area and increase area. With the increase of stress, the proportion of elastic potential in total coal and gas outburst energy increases, and the proportion of elastic potential is positively correlated with stress.
