摘　　要：针对在煤柱集中应力影响下采掘时冲击地压频繁发生这一现状,对峻德煤矿煤岩冲击倾向性以及3·15冲击事故进行分析,建立了叠加煤柱空间力学模型,对煤柱载荷进行估算,进行了相似材料模拟实验,提出了在煤柱影响下巨厚组合岩层垮落与冲击地压之间的关系。Aiming at stress concentration under the influence of the coal pillar mining rock burst occurred frequently,carries on the analysis to the coal and rock burst tendency of Junde coal mine and 3·15 rock burst accident,establish the mechanical model of coal pillar space superposition,to estimate the pillar load,carry out the similar material simulation test.This experiment puts forward that in the coal pillar under the influence of thick combined roof caving relationship between falls and rock burst.
