褶曲翼部诱发冲击地压分析

Analysis of induced rock burst in the folding wing

工作面过褶曲翼部,受采动影响,褶曲翼部区域出现能量积聚,导致人为诱发冲击危险因素。通过对回采工作面过褶曲构造区矿震显现分析,对11号煤层单一向斜构造区域内的聚能-释放-衰减聚能-再释放过程进行研究,分析力学成因与诱发机理,为后期回采工作面防冲提供参考。

when working face mined through folding wings, and affected by mining, the energy accumulation appear in the fold wing area, which lead to human induced impact risk factors. By the analysis of mine earthquake when working face mining a fold tectonic area, coal seam No. 11 single syncline structural area shaped - release decay energy - release were studied, the mechanics analysis of the causes and mechanism of induction were analyzed, which provide reference for the rock burst prevention in the later stage, the measurement and analysis showed that the stress concentration degree in the folding wing is high; the coal rock body energy in the influence area of mining activities fluctuates significantly.
