Performance of Raise Boring Machine (RBM) in Low to Moderately Hard Hornfels Rocks: A case Study of Efemcukuru Gold...
Abstract: Raise Boring Machine (RBM) provides a safe means of excavating a circular hole between two levels without the use of explosives. These machines were developed for the underground mining industry but nowadays is increasingly used on infrastructural projects. This paper aimed to assessment of the performance of a RBM during drilling / excavation of a ventilation shaft in the Efemcukuru Gold Mine,...

Prediction of Reaming Performance of Inclined Raises Using Pilot Hole Drilling
Abstract: Appropriate performance prediction of Raise Boring Machines (RBMs) in feasibility and planning stage of mechanized shaft excavation projects directly effects the economics of the projects and job completion time. This study aims to develop empirical performance prediction models for inclined reaming operations by using pilot hole drilling and reaming operational parameters and...
