The fire-retardant underground conveyor belts we carry meet a long list of regulations developed to protect workers and physical assets. These belts comply with international MSHA, CAN, and ISO standards. Our belts undergo rigorous factory testing to simulate the harsh realities of underground mining. They're designed to resist ignition and ...
West River Conveyors is the exclusive distributor of Depreux underground conveyor belts. For operations subject to MSHA Part 14 regulations we offer Firewall I and Firewall II multi-layer belts and the single-ply Firemaster-PVG textile belt. An alternative for operations not subject to Part 14 is the multi-ply Deltatherm textile belts.
Mining conveyor systems are getting larger, more durable and going underground One major trend that has the potential to boost the market for large conveyor installations is the large open pit mining operations going …
The open pit mining load and haul system has been a mainstay of the mining industry for many years. While machines have increased in size and scale and automation has become an important …
Mine ventilation (10.1%)—underground mines only. This chapter provides an overview of the current knowledge on energy used for materials handling during the extraction phase of mining operations and identifies opportunities to reduce energy consumption associated with these processes.

The mining industry is facing sustainable development challenges, among which the energy efficiency issues seem to be of major importance. As transport of the mined ore is considered as one of the most energy intensive operations, the improvement of its energy efficiency is a key indicator in terms of sustainable actions taken by mining …
The average haulage and hoisting costs for these groups ranged from $0.1135 to $0.4025 per ton of ore mined, and the range for 47 individual mines was from $0,086 …
There are several options for transporting ore from the mining sections to an underground main bunker. In the mining industry, rail systems, trucks, and conveyor belts, or a combination of these, are normally used. Rail haulage systems are mostly used in underground mines, which have high production rates and a long mine life.
Haulage systems are a major cost driver in underground bulk mining. Current haulage technologies are continually being reviewed because these methods may consume as much as 15%–30% of the overall capital investment in a mine as well as an ever-increasing portion of operational costs. In recent decades, the increase in production by bulk ...
5.1.2a: Shuttle Cars and Bridge Conveyors Shuttle Cars. Shuttle cars are a low-profile intermediate haulage option used predominantly in underground coal and some industrial minerals mines. Ore is loaded into the shuttle car at the face, and then it trams a relatively short distance, dumps its load, and returns to repeat the cycle.
Rail haulage once ruled underground mining but lost its dominant position due to the flexibility and investment advantages of truck or conveyor haulage. New locomotive technology makes a strong case for returning …
It can be divided into track transportation, trackless transportation, belt conveyor transportation, endless rope haulage, and aerial ropeway haulage. Track …

respectively. The mine uses four different mining methods: sublevel open stoping in zones A and B; drift and fill mining in zone C; narrow vein mining in zone C; Alimak mining in zones A and B. This paper focuses on the sublevel open stoping mining used in zone A. In this method, top and bottom accesses are mined to reach the sublevel open stope.
This chapter introduces the principal equipment used to load and haul materials in mines, namely trucks, electric rope shovels, hydraulic excavators and crushing and conveying systems. The chapter ...

The open pit mining load and haul system has been a mainstay of the mining industry for many years. While machines have increased in size and scale and automation has become an important development, there have been few innovations to the actual load and haul process itself in recent times. This research highlights some of the …
The Long Haul: Viper Mine conveyor carries coal 5.5 . The Long Haul: Viper Mine conveyor carries coal 5.5 miles . Tim Landis Wednesday Aug 29, . According to a project summary from Arch, the Illinois Office of Coal Development awarded 3 million to the company to build the conveyor belt and 1.7 million for mine-slope construction.

Let's look at the general characteristics of these materials-handling modes. We've already discussed LHDs, so let's begin with shuttle cars. 5.1.2a: Shuttle Cars and Bridge Conveyors. 5.1.2b: Mine Trucks, Haul Trucks, and Rail (Trains) 5.1.2c: Hoists, Hydraulic Transport, and Belt Conveyors.
RopeCon– directly out of the pit. RopeConis a suspended conveyor which transports your material on a flat belt with corrugated side walls and is perfectly suited for rugged terrain or to cross obstacles of all kind. As with conventional belt conveyors, the belt performs the haulage function. The belt is fixed to axles arranged at regular ...
The majority of these rules are echoed below: An underground mine is more economically served by a belt conveyor than railcars or trucks when the daily mine production exceeds 5,000 tons. (Source: Al Fernie) As a rule, a belt conveyor operation is more economical than truck haulage if the conveying distance exceeds 1 km (3,280 ft.).
