The choice of transportation system has an important impact on the production efficiency and economic behavior underground mines. Trackless vehicle gradually become main method in mines because mining companies have realized that can be improved using advanced mechanization automation process. extracted ore is loaded onto trucks by loaders situ, then drive to passes for unloading Trucks load un...

Since the beginning of civilization emergence, people began to use minerals extraction on surface Earth and rock mass transportation. One main tasks mining industry is transportation an increasing amount from quarry, which has caused need increase power carrying capacity dump trucks. Today, we can assume that revolutionary period in creation heavy-duty trucks over. Further improvement designs f...

In this research, an accurate optimization model, based on the Six Sigma methodology was used in order to assists marine container terminal operators to minimize trucks congestions. to smooth gate activity and to shorten trucks turn-around times. The main purpose of this paper is to report findings of implementing the Six Sigma in the landside of marine container terminals to reduce the average...

This paper describes a generic technology for modeling in real time the various operations of surface mines. Based on various sensor fusion techniques and high-speed network, a virtual reality model of a mine capable of representing not only static infrastructures but also mobile equipment such as trucks and excavators is created. The modeling technique deal with a wide range of sensors such as...

A path-tracking criterion for the so-called LHD (load-haul-dump) truck used in underground mining is proposed in this paper. It exploits the particular configuration of this vehicle, composed of two units connected by an actuated articulation. The task is to follow the path represented by the middle of the tunnel, maintaining the whole vehicle at a reduced distance from the path itself, to decr...

This paper describes the development of an algorithm that is able to track the pose of a vehicle as it approaches a rotating platform with a number of scanning range lasers. The target application is path planning and traffic management systems that are able to assist drivers of mining trucks when parking their vehicles with respect to loading machinery (ie. swing-loaders, rope-shovels and exca...

In mining, Fleet Management Systems (FMS) are useful tools for reporting and improving mine efficiency, though comprehensive FMS are expensive to install and maintain. This paper examines an alternative method using a particle filter algorithm to localise a fleet of haul trucks in a mine, providing most of the functionality of a complete FMS without the expensive hardware and installation. Most...

cross docking is a logistic strategy that plays the role of a middle knot in distribution network in the provision process. in logistic part, inventory holding is considered as an important matter in managing costs. not only cross docking reduces the inventory holding cost, but it also reduces the cost of collecting received orders, transportation and duration of sending. the products, which ar...

Many studies have been carried out and many commercial software applications have been developed to improve the performances of surface mining operations, especially for the loader-trucks cycle of surface mining. However, there have been quite few studies aiming to improve the mining process of underground mines. In underground mines, mobile mining equipment is mostly scheduled instinctively, w...
