摘要: 為了充分了解煤礦沖擊性災害的發生機理,探討了硐室開挖前后應力分布及其變化規律.結合原始地應力數據,通過室內巖石力學模擬實驗,獲得了不同巖性特征及受力狀態下,巖石破壞的不同表現模式.根據硐室圍巖破裂源的空間位置,將沖擊災害劃分為巖爆、沖擊地壓和礦震三大類.分析了三類沖擊災害的發生機理、孕育過程及宏觀特征.
- 地應力 /
- 巖爆 /
- 沖擊地壓 /
- 礦震 /
- 剛性實驗
Abstract: The law of stress distribution and its variation in rock roadway before and after excavation were studied so as to probe clearly the mechanism of impacting disasters in coal mines. Based on original in-situ stress data, rock damage modes under different rock characteristics and stress states were obtained by indoor rock mechanics simulation test. According to the location of rupture sources, impacting disasters had been divided into rock burst, pressure bump and mine earthquake. The mechanism, process and macro-characteristics of the three kinds of impacting disasters were analyzed.
- in-situ stress /
- rock burst /
- pressure bump /
- mine earthquake /
- rigid test
