摘要：

More that 40 coal-mine shaft-walls in East China ruptured during last two decades. Based on observation and simulation, a conclusion is drawn that most of them were induced by extra vertical stresses due to dewatering and compression of aquifers, chiefly due to drainage from the bottom aquifer of the loose Cenozoic strata (AQF4) to mine-pits. The aquifer system structure and model of shaft-wall's stress are analyzed respectively. The reinforcement techniques to ruptured shaft-walls are also discussed. Ground grouting is recommended as an effective technique.
