摘要
Abstract
The upper oxidized ore of No.1 ore body in the Huize Lead-Zinc Mine has remained suspended for many years,leading to the redistribution of in-situ stress within the area.It is necessary to study the engineering geological conditions of the mining area to establish a theoretical foundation for subsequent ore extraction.Based on the fundamental geological background of the mining area,combined with on-site structural plane surveys and rock mechanical parameter testing,the geotechnical conditions of the mining area were analyzed using the Q-system,BQ-system,and Protodyakonov classification method.The results indicate that the surrounding rock of the mining area is relatively hard(stable),the ore body is weak to moderately stable,and groundwater can easily affect the strength and quality of the oxidized ore.The overall geological conditions meet engineering requirements.Rational recommendations were proposed for engineering construction and mining,including excavation direction,support measures,and filling treatments,ensuring the normal extraction of oxidized ore in the target area.These findings provide valuable references for similar mining operations.关键词
