摘要
瓦厂坪铝土矿具有典型的适宜综合机械化开采的地质特征。通过分析液压支架不同型式的适应特点和瓦厂坪铝土矿矿体赋存条件,确定了支架型式及开采高度。通过岩重法和传递岩梁法2种方式进行分析计算,确定了液压支架的支护强度,为综采支护装备在铝土矿的应用及推广提供了选型思路。
Wachangping bauxite mine has typical geological characteristics suitable for fully mechanized mining.By analyzing the adaptability characteristics of different types of hydraulic supports and the occurrence conditions of ore body,the support type and mining height were determined.Through the calculations by rock mass method and transfer rock beam method,the support strength of hydraulic support was determined,which provides a solution for the application and popularization of fully mechanized mining support equipment in bauxite mine.
