摘要
随着地下工程不断地向着深部发展,岩爆地质灾害逐渐增多。国内外的学者就滞后型岩爆发生的机理及灾害预警进行了大量的试验研究,并利用超声波、电阻率等方法来探究滞后型岩爆的发生规律,以达到安全施工的目的。随着数值模拟软件的不断成熟,利用数值软件对深部硬岩开采过程进行模拟并与试验结果进行对比来解释滞后岩爆发生的机制,是当前深部硬岩岩爆问题研究的趋势。总结了近年来国内外有关深部硬岩损伤破坏的滞后效应研究进展和发展趋势,并提出了建议。
With the rapid development of deep underground excavation,rock bursts are always encountered.Many researchers have studied the mechanism of time-delayed rock bust through lab testing,ultrasonic wave testing and resistivity testing in order to ensure safe excavation.Meanwhile,numerical simulations were also used to understand the failure mechanisms of excavation and to compare with the lab test results.This paper summarized the research results and development of time-delayed rock burst.
