Numerical Study on an Applicable Underground Mining

2013-12-24  In underground mining of a coal seam that exceeds 10 m in thickness, extraction is mostly considered as dividing the seam into a number of slices/lifts and extracting each slice/lift with a longwall or bord-and-pillar using con-tinuous or conventional mining methods. In a multi-slice mining, the longwall caving system is the preferred prac-

Autonomous control of underground mining vehicles

This paper describes how many of the navigation techniques developed by the robotics research community over the last decade may be applied to a class of underground mining vehicles (local haul dump (LHD) and haul trucks). We review the current state of the art in this area and conclude that there are essentially two basic methods of navigation applicable. We describe an implementation of a ...
