| 摘 要： | 本文在分析研究大量受采动影响巷道的矿压显现规律和围岩变形的基础上,提出了巷道在采动期间的围岩变形量,以及采动稳定期间的围岩变形速度同护巷煤柱宽度之间的关系,并得出巷道服务期间的围岩变形总量与护巷煤柱宽度之间的关系式,为选择护巷煤柱宽度提供主要依据。

| Abstract: | Based on the analysis and research into the mine pressure manifestation law and surrounding rock deformation of a large number of roadways affected by mining activity, this paper raised a relation between the amount of surrounding rock deformation during mining activity, the velocity of surrounding rock deformation during stable stage and pillar width for roadway maintenance. Moreover, it established the relation between the total amount of surrounding rock deformation during service period of roadway and the pillar width for roadway maintenance. And this could be the principal basis for choosing the roadway pillar width. |
