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 000Hz,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。 Based on the analysis of the advantages and disadvantages of the existing devices, in order to realize the geostress, gas pressure and the physical and mechanical parameters of the coal body conveniently and adjustably, the design idea and technology of this simulation system are put forward based on the coal and gas outburst hypothesis and CSIRO model Claim. Using modular design ideas to develop successful coal and gas outburst simulation test system. The system can exert a maximum stress of 30 MPa and a gas pressure of 3 MPa. The gas pressure can be collected at a frequency of 1 000 Hz. The gas pressure and the high-speed camera can synchronously acquire and record the outstanding transient process information. The system is easy to operate, a single test speed, greatly reducing the test cycle. The results show that coal and gas outburst are affected by both ground stress, gas pressure and strength of coal and rock mass, in which the strength of the coal body hinders the protrusion and corresponds to the different coal and rock mass Destruction state, there is dynamic pressure of gas pressure threshold. Impetus to simulate the phenomenon of strong, prominent after hole into the mouth of a large cavity shape. The developed test system provides a scientific test instrument for in-depth analysis of coal and gas outburst mechanism.
