Purpose. To develop a methodology for determining the economically feasible distance of construction sand haulage, which is secondary raw material ore pits, to highway sites in comparison with delivery from mining enterprises building materials, taking into account land conservation indicators. Methodology. The research used set methods: analytical method – establish main technical and economic...

Interest from industry and policy makers on the use of autonomous goods vehicles (AGVs) for commercial use, has increased rapidly as underlying technology developed. This study looks at potential impact road haulage logistics operations barriers implementation in UK. The research focuses large vehicles, capable automated driving, where driver is not required some or all journey, between supplie...

This study stochastically predicted ore production through discrete event simulation using four different probability density functions for truck travel times. An underground limestone mine was selected as the area. The time measured by analyzing big data acquired from information and communications technology (ICT) systems in October 2018, (uniform, triangular, normal, observed distribution of...

Power haulage accounts for the greatest number of fatalities in Canadian, Australian, American, Indian, and Spanish mines, and is the fourth leading cause of fatal accidents in underground African mines. However, this rate is expected to grow with a move toward increased power haulage and less manual labour in Africa. Many of the fatal injuries have been associated with load-haul-dump (LHD) ope...

Road freight transport contributes to a significant and growing share of greenhouse gas emissions. This study analyses the development environmental practices awareness road hauliers whether witness an interest from their shippers towards energy efficiency. Results original survey (N = 256) conducted in 2019 among Finnish are presented compared with those similar completed 2011 295). The result...

Purpose. Substantiation of the conditions for haulage drifts stability using different protection methods in steeply dipping seams based on a set experimental studies. Methods. To achieve purpose set, mine instrumental observations have been performed to study rock pressure manifestations zonal advance workings adjacent stope face horizon. The their maintenance, within mining site, are assessed...

The paper analyses haulage equipment features of the Ural-20R borer miner. process loading ore with an auger is accompanied by circulation and grinding. This negatively affects efficiency mineral processing causes increased dust formation need to use energy-intensive methods reduce concentration in bottomhole space. authors work justify rational geometric parameters design combine, which will c...
