摘　　要：冲击地压严重威胁着煤矿的生产安全,给国家人民带来沉重的损失和代价。回采工作面附近的组合煤岩体,由于铅垂方向上不同层位的煤岩组合,导致其对能量的积聚能力存在差异且更为复杂,加之水平方向随着工作面的推进,因经历老初次来压、周期来压,使这部分组合煤岩体更容易产生能量聚集,造成冲击地压。本文通过论述组合煤岩体的相关研究对冲击地压防治的意义,同时对其研究进展进行概括分析,希望能对冲击地压的防治有所帮助。Rock burst is a serious threat to the production safety of coal mines,and brings heavy losses and costs to the people of the country.The combined coal and rock mass near the working face,due to the coal and rock combination of different horizons in the vertical direction,leads to the difference of energy accumulation ability and more complex.In addition,with the advance of the working face in the horizontal direction,because of the old initial weighting and periodic weighting,this part of the combined coal and rock mass is more likely to produce energy accumulation,resulting in rock burst.This paper discusses the significance of the related research of combined coal and rock mass to the prevention and control of rock burst,and summarizes the research progress,hoping to be helpful to the prevention and control of rock burst.
