深井矿山岩爆的预测预报及其防治技术

Prediction and prevention technology of rock burst in deep mines

  • 摘要: 在深井矿山中,岩爆的发生极大地威胁着井下人员设备材料的安全,对岩爆的预测预报变得越来越重要.文中在总结国内外学者在岩爆研究成果的基础上,对岩爆的发生机理及其常用岩爆判据进行研究分析,指出当前的岩爆判据大体上都是围绕着岩体的物理力学性质、受力状态以及储能情况等3个方面进行研究分析的. 利用单一判别指标进行岩爆预测会存在一定的局限性,应综合考虑多种判别指标进行岩爆的预测预报. 最后介绍了实际矿山中几种常用的岩爆预测预报方法及其防治技术,对矿山岩爆的预测预报及其防治具有一定的指导作用.

     

    Abstract: In the deep mining, the occurrence of rock burst has been greatly threatening the safety of underground personnel and equipment and material. It becomes more and more important to predict the rock burst. On the basis of summarizing domestic and foreign scholars research results in rock burst, the mechanism and the commonly used criterion of the rock burst were studied to indicate that the current criterion of rock burst was substantially focusing on three aspects, namely the physical and mechanical properties of rock mass, strained condition and the energy storage condition. With the limitation of using a single evaluation index to predict rock burst, a variety of evaluation indexes for the prediction of rock burst should be considered. In the end, several common methods used in rock burst prediction and prevention techniques in an actual mining were discussed, which had a guiding significance for the prediction and prevention of rock burst.
