地质工程力学研究所研究出了掘进巷道时能降低工作面附近煤层突出危险性的振动法.这个方法的实质在于,在振动作用下,活化了煤体中裂隙形成的过程,使煤体显现出卸压和瓦斯排放的非弹性性质.这时,振动器应布置在煤体中,布置方式应使其工作时能利用工作面附近煤层的最大应力-应变状态,以活化瓦斯排放和卸压裂隙形成的过程.如果振动器(考虑到其有效作用半径)布
The Institute of Geotechnical Engineering has developed a vibration method that can reduce the outburst danger of the coal seam near the working face when driving a roadway.The essence of this method is that under the action of vibration, the process of crack formation in the coal body is activated and the coal body appears Pressure relief and non-elastic properties of gas emission .At this time, the vibrator should be arranged in the coal body, and should be arranged so that it can utilize the maximum stress-strain state of the coal seam in the vicinity of the working face to activate the gas drainage and pressure relief cracks Forming process.
