摘要在分析现有装置优势与不足的基础上，为实现地应力、瓦斯压力和煤体物理力学参数方便可调，基于煤与瓦斯突出综合作用假说与CSIRO模型，提出本模拟系统的设计思想和技术要求。采用模块化的设计思路研制成功煤与瓦斯突出模拟试验系统。该系统最大可施加30 MPa地应力和3 MPa气体压力，气体压力采集频率高达1 000 Hz，气体压力和高速摄像同步采集实现对突出瞬态过程信息的精确记录。该系统操作便捷，单次试验速度快，大大缩短了试验周期。模拟9组含瓦斯煤的石门揭煤突出试验，试验结果表明：煤与瓦斯突出受地应力、瓦斯压力和煤岩体强度共同影响，其中煤体强度对突出起阻碍作用，对应不同煤岩体破坏状态，存在瓦斯压力动态临界值。模拟试验动力现象强烈，突出后孔洞成明显的口小腔大形态。研制的试验系统为深入分析煤与瓦斯突出机制提供了科学试验仪器。

Abstract：To achieve the adjustability of the parameters of geostress，gas pressure and coal properties，some design ideas and technical requirements of the simulation system were proposed based on the hypothesis of combined effects and CSIRO model after analyzing the advantages and disadvantages of existing devices. The simulation system was developed with the modular design idea. The system can apply geostress up to 30 MPa and gas stress up to 3 MPa. The acquisition frequency of gas pressure is up to 1 000 Hz. Synchronized acquisition of gas pressure and speed achieved precise record of the prominent transient information. The system is easy to operate and the single test is fast which shorten the testing cycles. 9 groups of crosscut exposing coal outburst simulation test of gas filled coal were carried out. The test results showed that coal and gas outburst was affected by the combined effect of geostress，gas pressure and coal strength. The coal strength prevented the outburst. The dynamic thresholds of gas pressure existed corresponding to different damage states of coal. The dynamic phenomena appeared strongly，and the cavities were large inside with small exit holes after outburst.
