摘要
为研究瓦斯压力对煤与瓦斯突出强度的影响,改进一套煤与瓦斯突出模拟试验装置,增加气体压力传感器和温度传感器。研究煤与瓦斯突出过程中的瓦斯压力、温度变化,分析突出过程中各参数的演化规律。进行瓦斯压力分别为0.60、0.80、0.90、1.00 MPa的煤与瓦斯突出模拟试验。
In order to study the influence of gas pressure on intensity of coal and gas outburst, a set of apparatus for simulating coal and gas outburst was improved by adding gas and temperature sensors. The evolution rule of separate parameters is analyzed, such as gas pressure, temperature during the outburst. Hence, the simulating test of coal and gas outburst was conducted while the gas pressure are 0.60.0.80, 0.90, 1.00 MPa respectively.
