摘要

目前对旨在评估岩石强度的实验研究关注不足。因此，本文的目的是研究主断裂带在压缩和拉伸条件下岩石性质的变化。该研究论文综述了评估易发生岩爆的矿山工作区断裂活动的方法。已经使用目前市场上可用的声学和电磁发射检测设备（设备）确定了检测矿井岩体近裂缝变化的可能性。已经开展了确定岩石样品单轴和三轴加载期间的声发射（AE）和电磁辐射（EMR）参数的工作。

Methods for determining rockburst in mining workings

Insufficient attention is currently paid to experimental studies aimed to assess the rock strength. Therefore, the objective of this paper is to study the changes in rock properties in the main fracture zone under compression and stretching conditions. The research paper reviews methods to assess fracture activity in mine workings prone to rock bursts. The possibility of detecting near-fracture changes in the rock mass of the mine workings has been determined using acoustic and electromagnetic emission detection devices (equipment) currently available on the market. Work has been carried out to determine acoustic emission (AE) and electromagnetic radiation (EMR) parameters during uniaxial and triaxial loading of rock samples.
