There are two basic options for the underground transport of materials and equipment: track/rail systems and trackless systems. Most underground mines use the latter only. In

Read MoreMining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground
Read MoreDespite a proliferation of research in the area of mapping in the mobile robotics community, the practical realization of a truly useful and low-cost mapping technology for drift networks in underground mining has yet to become available. To this end, this paper presents recent industry-directed work in the development of a globally consistent occupancy grid mapping tool that combines odometry ...

Presented are field results that compare the proposed approach with previously published algorithms, as well as with manually acquired measurements.
Read MoreUnderground mining takes place in several stages: ... A single drift can include 15-40 fan cuts, with each fan cut containing eight drill holes. Drilling is performed with a remotely controlled drilling unit, which is operated and monitored by operators from a control room. When production drilling is ready throughout the drift, a special ...

Read MoreUnderground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
