摘要：冲击倾向性问题一直是冲击地压研究中的热点问题之一。国家推荐GB/T 25217.3—2019标准对煤岩组合试件冲击倾向性分级评价进行了规范,该标准于2020年开始实施。针对该标准的内容,采用文献回溯法,重点对中文文献中与此相关的文献进行汇总分析。调研认为:目前煤岩组合体冲击倾向性实验研究的数量相对较少,基于该标准所提出的剩余能量指数法评价煤岩组合体冲击倾向性尚不具备大量实验数据支撑条件,且该标准在试样采集、试件组合方式、剩余能量指数测定等方面还存在一些问题需要进一步深入研究,其关于冲击倾向性的分级标准有过于宽泛和不够精准之嫌。有鉴于此,认为该标准作为国家推荐标准投入实施的时机尚不成熟。
Burst tendency has always been one of the hot issues in the research of rock burst.The national recommended standard GB/T 25217.3—2019 regulates the evaluation of the burst tendency of combined coal and rock specimens.The standard is implemented in 2020.Aiming at the content of this standard,this paper adopts the method of literature backtracking,focusing on the analysis of related Chinese literature.According to the survey,there are relatively few experimental studies on the burst tendency of coal-rock combinations,and there is not sufficient experimental data to support the residual energy index method which was proposed by this standard to assess the burst tendency of combined coal and rock specimens.Also,here still are some problems in sample collection,test piece assembly,and determination of residual energy index,which require further in-depth research.Overall,the classification criteria for the burst tendency are too broad and not accurate enough.In view of this,it is considered that the time for the implementation of this standard as a nationally recommended standard is still immature.
