Effect of Operational Parameters on the Performance of Raise Boring Machine During Pilot Drilling
Abstract: Raise Boring Machines (RBMs) are the fast, safe and efficient drilling / boring machines are used for different purposes in mining and tunnelling especially for excavation of vertical and/or inclined shafts and drifts. The optimum raise boring system is designed or selected based on drilling / excavation performance, which depends mainly on mechanical (machine related), geological /...

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...

Raise Boring Machine performance in the Yusufeli Dam and HEPP Project
Abstract: Performance of a Raise Boring Machine (RBM) used in Yusufeli HEPP project in Turkey is evaluated in this study. The depth and diameter of the energy shaft are 130 m and 2.44 m, respectively. The drill core samples were obtained from the site (diabase and granodiorite) and compressive strength, tensile strength, static elasticity modulus and Poisson’s ratio, dynamic elasticity modulus and...
