| 摘 要： | 根据对巷道底鼓影响因素的分析，得出巷道底鼓机理：在膨胀型软岩的特殊围岩条件下，由于水的作用使巷道底板岩层破坏范围加大，再加上集中应力的作用，最终形成膨胀型底鼓和挤压流动型底鼓。

| Abstract: | Based on analyzing the factors of influence on the floor lift,the mechanism of gate floor lifts is researched: Under the spechial conditions of swelling soft surrounding rock,the damage range of roadway floor rock increased because of the role of water,coupled with the effect of concentrated stress,expanded type and squeezing flow type floor heave is formed at last. |
