摘要
煤与瓦斯突出的主要驱动因素包括瓦斯压力和地应力。为对瓦斯压力与地应力的控制效应进行研究,设计了煤与瓦斯突出模拟试验系统,包括单瓦斯压力试验机和瓦斯压力、地应力综合试验机。该试验系统可对煤样施加2MPa的瓦斯压力和40MPa的地应力,与已有的煤与瓦斯突出模拟试验系统相比,其技术特点是可控性强、加载能力高,采用数据记录和图像记录同步的方法,实验结果更准确。
The main exciting factors include gas pressure and strata stress.For studying the control effect of gas pressure and strata stress,a simulation test system for coal and gas outburst was designed,including a single test machine for gas pressure and a combined test machine for both gas pressure and strata stress.This test system can exert a gas pressure of 2 MPa and a strata stress of 40 MPa on the coal sample,as compared with the existent simulation test system of coal and gas outburst,this system has the technical features of strong controllability,high loading capacity,synchronous data and image recording and accurate experimental results.
