The Effect of Rock Anisotropy on the Excavation Rate in Barre Granite
نویسندگان
چکیده
The variation in the volume of rock removed when a water jet traverses over a sample of Barre Granite is shown to vary with the angle at which the sample is cut relative to the orientation of the main deposit. For example where the jet impacts perpendicular to a microfissure plane a channel up to 10 times the volume is cut as when the jet is traversed along the microfissure plane. A correlation is shown to exist between the dimensions of the rock volume removed and the angle of impact between the water jet and the two microfissure planes of the Barre Granite.

Performance Analysis of Nail Walls in Jointed Rocks Based on Excavation-Induced Damage
Evaluation of the excavation-induced ground movements is an important design aspect of supporting system in urban areas. This evaluation process is more critical to the old buildings or sensitive structures which exist in the excavation-affected zone. Frame distortion and crack generation are predictor, of building damage resulted from excavation-induced ground movements, which pose challenges ...

The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

Original scientific paper Rock burst is a common serious geological hazard in underground engineering, which seriously affects the progress of projects. The mechanism of rock burst can be explained by the distribution law of rock fragments and its fractal characteristics. A simulation experiment of rock burst was conducted with the granite samples under a biaxial loading machine system to analy...
متن کاملThe Use of Waterjets in Cutting Granite
High pressure waterjets are now entering use on an increasing scale for primary rock excavation in quarries. In order to assess the parameters required for any such rock cutting operation a series of experiments need to be carried out in which the critical operational parameters are identified. This paper seeks to identify such a standard procedure with an explanation with the reasons for choic...
