摘　　要：为降低采区煤柱区域冲击动力显现频率和程度,提出深井采区煤柱存在刚性核体、冲击核体和柔性层,研究了煤柱中冲击核体特征和变化规律,揭示了深井采区煤柱冲击地压发生机理。构建了深井采区煤柱冲击地压防范、监测预警、治理防护的技术体系,进行了现场实践应用、效果检验,防控技术降低了煤柱区域动力显现频率和程度,有效地消除了深部采区煤柱区冲击地压的发生。To reduce burst strata behaviors frequency and power in mining area coal pillar areas, we propose that the deep well mining area coal pillar has rigid nuclear body, impact nuclear body and flexible layer. Impact nuclear body characteristics and change laws in the pillar were studied. It reveals occurrence mechanism of rock burst in deep mining area coal pillar areas.Technology system of the prevention and treatment as well as monitoring and warning of rock burst in deep mining area coal pillar areas was constructed. Through the field practice application and effect test, strata behaviors frequency and power in mining area coal pillar areas was reduced by prevention technology, and rock burst in deep mining area coal pillar was eliminated effectively.
