| 摘 要： | 以自行研制开发的大型煤与瓦斯突出模拟试验系统为手段，对其可靠性进行试验验证，并对不同含水率煤体发生煤与瓦斯突出时突出强度变化规律进行模拟试验研究。结果表明：研制开发的大型煤与瓦斯突出模拟试验系统的模拟试验结果与煤与瓦斯突出事故实际较吻合，且系统可靠性较好；随着含水率的升高，煤体发生煤与瓦斯突出的可能性减小，煤与瓦斯突出强度也呈减小趋势；在试验煤体含水率情况下，含水率与煤与瓦斯突出强度呈二次曲线关系。

| Abstract: | Based on self-developed large-scale simulation test system of coal and gas outburst，experimental verification of its reliability is carried out；and experimental study of simulation of variation laws of intensity of coal and gas outburst is done under different water contents of coal as well. It is shown that：(1) the simulation results obtained by the large scale simulation test system of coal and gas outburst are fairly consistent with actual results of coal and gas outburst；(2) the reliability is satisfactory；(3) both possibility and intensity of coal and gas outburst decrease with the increase of water contents of coal；and (4) under the test conditions，the relationship between the water contents and intensity of coal and gas outburst is conic. |
