Intermodal transport, the combination and integration of several transport modes, with the use of loading units, is in most cases more environmentally friendly than unimodal road transport for the carriage of goods. The LAMBIT-model (Location Analysis Model for Belgian Intermodal Terminals) has been developed to analyse the market areas of existing and potential intermodal terminals. In the LAM...
Surface mining comprises complex geometries, dangerous operations and human controlled machines. Due to human errors, unstable layouts, geological deformations, and design problems, safety and health hazards including fatal accidents occur. The 2016 fatal accidents review by the Mine Safety and Health Administration (MSHA) showed that mobile machines accounted for 58.3% (2012), 36.4% (2013), 39...
Method to haulage path estimation and road-quality assessment using inertial sensors on LHD machines
In this study, a mine production management application (app) using Bluetooth beacon and tablet PC was developed to support the efficient operation of an underground loading-transport system. The app receives signals from beacons attached major loading points crushing sites through mounted on truck records time were received as well location truck. addition, when signal beacon, driver can selec...
The main aim of blasting operations in mining and civil engineering projects is size reduction of the rock-mass. Particle size reduction (P.S.R) affects the efficiency of the loading, haulage and milling equipments. Therefore, prediction of mean fragment size in designing optimum blasting patterns is crucial. In this research, a model is presented for predicting mean fragment size caused by bla...
