摘要/Abstract

摘要： 结合西石门铁矿现场勘探资料及岩石力学试验数据，并综合考虑巷道工程特性等因素，分别采用RMR法和BQ法对矿区南、中、北3个采区的巷道围岩进行工程质量分级和评判。综合确定了各矿区巷道围岩的稳定性，从而为采用更加经济、安全的支护措施提供可靠的科学依据。

关键词: RMR法, BQ法, 围岩稳定性

Abstract: Combining with the filed exploration data of the Xishimen iron mine and the experimental data of rock mechanics,the roadway engineering properties and other factors are con siderated comprehensively.Engineering quality classification and evaluation of roadway surrounding rock of three mining area in the south,middle and north mining area are carried out by means of RMR and BQ method respectively.Surrounding rock stability of various cola roadway is determined effectively.Therefor,this research result can provide some reliable scientific basis for taking mor economic and safe measure in this field.

Key words: RMR method, BQ method, Stability of the surrounding rock
