The selection of equipment for haulage in underground mines is a challenge due to its impact on both production rates and costs. The selected equipment should create an optimal match for the complete system and the point when equipment is to be added or replaced needs to be identified before the change is made. The use of discrete event simulation to compare two different …

2020. One of the key issues in mining is the hauling system. Truck and shovels are the most widely used transportation equipment in mines. In this paper, a two-phase simulation-based optimization is presented to maximize utilization of hauling system in …

– Underground Trucks are the backbone of underground mining haulage. These trucks are designed to carry heavy loads over long distances through rough, uneven terrain. ... – Conveyor Systems are often used in conjunction with other haulage equipment to continuously move material from one part of the mine to another. These systems are highly ...

the goal [4]. To reduce the ineffective travel time of haulage equipment, Yardimci and Karpuz proposed a shortest-path optimization method for underground mine haulage road design based on the evolutionary algorithm. This method considers kinematic constraints such as minimum turning radius and maximum slope to determine the optimal haulage ...

Current haulage techniques are a significant cost driver, which account for between 15 and 30% of the overall capital investment (capex) in a mine and are an increasingly part of the operating …

with underground mining services provided by Barminco (an underground mining contracting arm of Perenti). The mine includes historical workings completed prior to 2012. The underground mine was reopened in early 2019, and at the commencement of the Study in mid-2023 the site was in a project development phase.

A Bluetooth beacon-based underground navigation system (BBUNS) was developed to identify the optimal haul road in an underground mine, track the locations of dump trucks, and display this information on mobile devices. A three-dimensional (3-D) geographic information system (GIS) database of the haul roads in an underground mine was constructed, …

Digital simulation was used to model a proposed underground' train system. The trains are to haul ore from numerous loading points beneath the production area of the mine to a central underground dump location, and then return to the mine. The purpose of the simulation was to aid mine engineers in studying various alternatives and configurations regarding track layout, …

underground through shafts or drifts, they are transported by a variety of diesel and electric (including battery) powered track mounted and trackless systems. There are two basic options …

Mechanical Haulage. In considering mechanical vs. hand or animal haulage in a mine or section of a mine, a factor that always must be considered is the duty to be performed.

Rail haulage roadway is the roadway that accommodates a rail for the rail vehicles such as electric locomotive and mine car. Most medium or small underground mines in China use rail haulage (Fig. 1).In large mines, rail haulage is mostly used at the level for centralized transportation of ore, while the other levels mostly use trackless roadway.

haulage in Australian underground hard rock mines is 5.5m high x 5.5m wide. Thus, mines are designed with decline truck haulage in mind resulting in almost an invincible

In many underground mines, haulage vehicles (trucks or road trains) carry ore from underground loading stations to the surface. Vehicles travel in declines with occasional passing bays that allow ...

Based on the existing research, in order to ensure the completion of the original operation plan on time, the multi-equipment is rescheduled, and an optimization method for an underground mine haulage equipment rescheduling plan based on random breakdowns simulation is proposed, aimed at the scheduling problem in the case of the breakdown of ...

This report describes underground haulage methods and equipment, presents cost analyses, and discusses future plans for underground transportation in metal mines. It does not cover …

In underground mining, the truck-loader haulage system involves mucking of the material from the working face and transporting it to the dumping point where it is reloaded into trucks for further ...

Transportation of materials underground has become of vital importance.1"0 This report describes underground haulage methods and equipment, presents cost analyses, and discusses future …

Moreover, during the haulage some ore will inevitably spill. What is the actual payload? One true ... while Australia has managed to keep one of the lowest ratio of underground mines in proportion to open cut mines in the world, undoubtedly this will soon change and the viability of the new underground operations will be… in the truck's ...

This paper presents the results of a case study in which the big data created by an ICT-based mine safety management system are used for simulating truck haulage operations. An underground ...

In South Africa, rail haulage is the principal transportation method in underground mining operations and will remain a significant factor in future.

This paper considers the identification of viable haulage technologies for underground mines and explores an approach for assessing existing and potential …

All underground mines face the challenge of productively transporting ore to the surface for processing. Shaft hoisting is often the most efficient means of moving the ore, which is normally blasted rock, but in some instances (especially in shallow mines) the high cost of shaft-sinking is not justified [1], [2].In these and other specialized cases, the burden of ore and/or …

The document discusses optimizing the truck-loader haulage system in an underground mine through simulation. It describes the current system which uses 3 LHD loaders and 3 trucks across 3 stopes. Data on cycle times was collected. A simulation study using SimMine software evaluated increasing the number of trucks. The results showed the loading equipment capacity …

In this study, a mine production management application (app) using a Bluetooth beacon and tablet PC was developed to support the efficient operation of an underground mine loading-transport system.
