摘要
根据三门峡铝土矿岩层特点及工程概况,研究复杂情况下岩层特性,得出围岩的破坏成因,并阐述围岩支护结构的作用机理,提出支护结构的优化参数,给出支护方案及施工工艺过程,通过有限元论证支护方案的可行性,达到全面合理的评价效果。
According to the features of Sanmenxia bauxite mine and engineering overview,we have studied the characteristics of stratum under complicated geological conditions and concluded the reasons why surrounding rock destroyed. Besides,we have stated the mechanism of support structure, proposed op- timization parameters of support structure and given support programs and construction process. Feasibilities of support programs have also been proved by finite element, so evaluation results are complete and reasonable.
