摘要：
In order to study the influence of gas content on the strength of coal and gas outburst, a set of device for simulating coal and gas outburst is improved by adding flowmeter and gas pressure sensors. The simulation experiments of coal and gas outburst were carried out with gas content of 7.5m3/t, 8.0m3/t, 8.5m3/t and 9.0m3/t respectively. The test results show that with the increase of gas content, the weight of outburst coal and the outburst distance increases gradually, the variation trend of crushing is not obvious either.
