If continuously forced toward the same side of the wall, overbreak
occurs and the bit naturally wanders in that direction.
In [18, 19], artificial neural networks were combined with multiregression in order to optimize overbreak
ABSTRACT: Discontinuities are an integral part of the rock masses and pose special problems in blasting operations in mining and civil industries resulting in high excavation cost due to underbreak and overbreak

Any dilution from overbreak
also contains lower grade mineralisation that has been quantified by estimation against the Resource model
Zip-It bags from Overbreak
LLC, Sun Valley, Calif., come in a variety of sizes and, since they start out so small, you can bring more than one on road trips.
Possible applications, amongst others, include milling of trenches down to a width of 700 mm -- true to profile and without unnecessary overbreak
, tunnelling, demolition and asphalt cutting.
It automatically scans overbreak
and underbreak to save valuable time during the drilling cycle, helping customers develop more meters every month.
