摘　　要：从力学模型入手,按相似理论设计了三维煤与瓦斯突出模拟实验装置,实验模拟了不同煤型强度、三向应力、瓦斯压力条件下的煤与瓦斯突出过程,得出了突出强度同瓦斯压力、煤型强度、三向应力、瓦斯压力关系数学模型,分析认为,应力和煤的力学性质是决定突出强度的主要因素.Based on the mechanical model and simulation theory, a 3-D experimental system was designed and established to simulate coal and gas outburst. Outbursts were simulated under conditions with different coal strengths, stress status and gas pressures, and a mathematical model was established to describe the relationship between outburst scales and the parameters previously mentioned. Stress status and coal mechanics property are main factors to decide outburst scales .
