| 摘 要： | 岩石扩容与围岩性质及应力状态密切相关.本文在描述岩石扩容现象的基础上,运用现有的岩石扩容本构方程,得出了求解扩容引起的底臌量的表达式,它适用于煤矿井下巷道.基于该公式,分析了实际巷道中扩容对底臌的影响程度及与之有关的诸因素.最后阐明了在软岩、大地压巷道中,扩容是引起底臌的一个重要原因,并论述了各种防治底臌的措施控制岩石扩容的机理.

| Abstract: | Rock dilatancy is closely related to the properties of surrounding strata and stress states. Based on discribing the appearance of rock dilatancy, the formula for calculating the floor heave caused by dilatancy is obtained, Which is suitable for coal mining openings. Applying this formula, the affecting degree to floor heave by dilatancy and the factors related to it are analysed. Finally, at is pointedout that dilatancy is an important reason for floor heaue, and the mechanics controlling rock diatancy by various methods for preventing and controlling floor heave is discussed. |
