Q系统方法在采场支护设计中的应用与实践

APPLICATION OF Q-SYSTEM TO STOPE SUPPORT DESIGN

岩体分类法是地下井巷工程支护设计的基本方法。本文研究了ＮＧＩ的Ｑ系统分类法在采场支护设计中的应用。为消除Ｑ值确定过程中的主观性。研究了Ｑ值各影响参数的量化技术，应用模糊集理论分析了各参数值的模糊性。结合云南某矿试验采场，确定了采场岩体质量Ｑ的模糊分布，达到合理设计采场支护方案的目的。

his paper presents the application of Q一system for rock qual ity classific。ation to underground stope support design,To prevent the subjectivity from0value determination,the technique for parameters quantifying is developed。By using the fuzzy set theory,fuzzy distribution of each parameter is studied。Applied to a practical design for a n1ine in Yunnan,the fuzzy distributionof rock quality Q is determined,and reasonable support scheme is worked out accordingly。
