摘　　要：为从细观结构层次上研究深部水平矿井的煤与瓦斯突出特性,利用RFPA2D软件系统对深水平煤岩的地应力、煤体瓦斯压力、围岩温度、煤与瓦斯突出的关系进行了数值模拟研究。结果表明:在深部水平,高地应力、高瓦斯压力和高温度梯度与煤岩体软弱、强度降低的矛盾更加突出,在工程扰动下更容易发生煤与瓦斯突出灾害。In order to study the coal and gas outburst features of the deep section level in the mine based on the micro structure level, the RFPA^2D software system was applied to the numerical simulation study on the relationship between the ground stress, the seam gas pressure, the surrounding rock temperature and the coal and gas outburst of the deep coal and rock in the mine. The results showed that in the deep level of the mine, the contradiction between the high ground stress, high gas pressure, high temperature gradient and the coal and rock mass soft, weak and hardness in reduction would be more obvious. Under the project interferences, the coal and gas outburst disaster would be easily occurred.
