For open pit mines taking shovel-truck system as a major stripping system, the overburden transport costs can be accounted for 1/3 or more open pit operating costs. Therefore, shortening transport distance to reduce transport costs has become an important problem in nearly horizontal open pit mine.
Table 1—Comparison between conventional truck traffic and the new skip-conveying system in an open-pit mine. Economic Comparison As a way of illustrating the advantages of TKF’s system over conventional truck haulage, a number of assumptions have been made to provide the basic parameters for the comparison.

Transportation costs have always been a significant part of capital and operating costs of large open pit mines. In pit crushing and conveying system is going to be a significant part of future
Abstract. As open cut mines become progressively deeper, mining operations face increased operating costs and technical challenges. In-Pit Crusher Conveyor (IPCC) systems offer advantages in the form of continuous operation, reduced labour requirements and decreased energy consumption resulting in lower cost per bank cubic metre.
Operational costs, worker safety and CO2 emissions are challenges faced by most mines and quarries today. While there certainly isn’t a silver bullet that would solve all problems overnight, in-pit solutions, such as in-pit crushing and conveying (IPCC) are widely recognized as a good place to start.
2.1 Cost Categorization. In this paper, costs in open pit mines are categorized into four groups: (1) capital costs, (2) operating costs, (3) general and administrative (G&A) costs, and (4) fixed

• In a hard rock mine, the product from a jaw crusher to feed a conveyor belt will have a size distribution such that the -80% fraction size is slightly less than the open side setting of the crusher. For example, if the open side setting of the underground jaw crusher is 6 inches, then the d80 product size = 5¾ inches. Source: Unknown
Mt Whaleback is one of the largest open-cut iron ore mines in the world. Haulage cost is the single largest component of operating costs at the mine. Past studies towards alternatives to truck haulage have recognised the potential viability of an in-pit crushing and conveying system, dependent on the proportion of uphill haulage. After seventeen years of mining Mt Whaleback still contains more
Since the nineteen-sixties, belt conveying has continued to make great strides in soft-rock open-pit mining, becoming the most important means of transport in this sector; belt conveyor systems in current use with bucket wheel excavators achieve performances per day of up to 240000 m³ bank.
Todays open pit mines operate in ever-more-remote locations under harsh conditions. They need to manage increasing transport distances. And they face volatile raw material prices and increasing energy costs. In this situation, control over energy performance and equipment condition becomes key. Digital mining can help.

The depth of the open pit mines have increased considerably over the last several years. In fact, there are some open pit mines that are reaching a depth of more than 1000 meters. Currently, the use of conventional trucks for transporting material is probably one of the most flexible systems in open pit mines.
Severstal is readying an investment in a new conveyor system at the Karelsky Okatysh iron ore complex in northwest Russia as part of a major project to reduce haulage costs at the Tsentralniy open-pit mine. In the company’s capital investment 2020 announcement at the end of January, it said one of the major investment projects being run by

Normally track-mounted, they are of PA300 The mobile cross pit spreader (CPS) wheel excavator loads the waste material to the system, developed and customized for special boom of the cross pit spreader, which conveys applications, has been built to over 350 meters the waste material across the open pit and dis- (1,150 ft) in length.
Construction at Black Thunder began in 1976 with the installation of crushing, conveying, sampling and high-speed train-loading systems. All plant processes are computer-controlled, including the precision loadout systems and the high-tech, near-pit crushing and conveying system installed in 1989.

The vendors indicate the conveying system should be able to achieve heights of 700 metres. This may facilitate the use of internal shafts (winzes) to hoist ore from even greater depths in an expanding underground mine. It may be worth a look at your mine. As stated earlier, I have no personal experience with vertical conveying.
FAM Drive Stations. An open pit mine is a complex dynamic facility composed of many large mobile units and powerful conveyor systems, which are regularly and completely moved in line with the mining operation. Conveyor lines are relocated with the help of so-called shifting crawlers. Drive stations, as well as take-up and deflection stations of
