That is the daily challenge for the operators of the giant dump trucks used in surface mines. As a result, each year, an average of 20 accidents and three fatalities occur involving collisions between a piece of surface mining haulage equipment and either a smaller vehicle, a worker, or some other object. Another 21 accidents occur and three mining equipment operators are killed each year when ...

This paper focuses on the sequencing and scheduling problem of open pit mining, with the allocation of loading equipment considering a medium-term horizon. This study considers the existence of a heterogeneous loading equipment fleet and two types of mineable material, namely ore or waste rock. For the mining of ore, the following requirements are taken under consideration: the mixture quality,...

This paper describes the adoption of the Ethernet/IP standard in the development of a specification for the interconnection of mining equipment as part of an industry-sponsored Landmark longwall automation project. Longwall mining is used extensively worldwide and accounts for the majority of underground coal production in Australia and the USA. Full automation of the longwall mining process is...

Abstract. In a simple surface mining scenario we can consider the mine to have one mining location and one dump-site connected by a lone truck route. Our objective is to determine a purchase and salvage policy for trucks and loaders such that the cost of materials handling is minimized over a multiple period schedule. This problem quickly becomes large scale when we consider large sets of possi...

Studies conducted on surface coal mining equipment have identified whole-body vibration as a significant hazard. Operators of underground mobile equipment, particularly shuttle cars and transport vehicles, are likely to be exposed to significant levels of whole-body vibration. To date, measuring whole-body vibration from underground mining mobile equipment has been difficult due to the strict g...
