| 摘 要： | 采用煤矿冲击区域钻屑检测量与煤体应力变化的研究成果，根据钻屑法在检测冲击危险程度过程中存在的煤体水平应力与垂直应力不等原理，结合义煤公司跃进煤矿防冲工作面钻屑法应用情况，建立了钻屑检测量和煤体应力之间的定量关系，得出防冲工作面煤体应力变化规律，确立了防冲工作面超前应力集中分布区域和钻屑检测临界值，为矿井制定针对性的防治冲击地压措施、最大限度地降低因冲击地压造成的危害提供技术支撑。

| Abstract: | Based on the research results of drilling cutting quantity and changes of coal stress in coal mine area with rockburst danger，according to the coal level of drilling method in risk degree detection during impact stress and vertical stress ranging principle，combined with the drilling method applied in Yuejin Coal Mine of Yima Coal Industry Company，the quantitative relationship between drilling cuttings detection volume and coal body stress was established，and the law of coal stress variation was obtained.The critical stress concentration distribution areas and cuttings detection critical values were established，and the aim of the mine is to formulate measures to prevent and control rock burst，and provide technical support to minimize the harm caused by rock burst. |
