摘要
为查明林南仓煤矿三水平东一采区巷道围岩大变形原因及特点,提出合理有效的支护对策;针对东一采区地质条件及工程状况,提出了锚注架喷的支护方式,指出该支护是适合林南仓矿高应力软岩特点的合理支护形式,为工程实践中有效的控制巷道变形提供依据。
To identify the deformation reason and feature of the third level No. 1 east mining area surrounding rock of Linnancang Mine, the support of bolt-grouting and spraying was put forward, with reasonable and effect support, the technology provided reference for controlling roadway deformation in practice.
