West African Guinea is known for possessing the largest reserves of high-quality bauxite in the world. This potential has prompted the country to continually expand its bauxite mining sector in recent years, making substantial investments. During the mining process, WIRTGEN machines produce level surfaces that serve as stable roadways, facilitating rapid transportation of the mined material. WIRTGEN supplies surface miners in a variety of performance classes for the selective mining of raw materials, such as coal, limestone, bauxite, gypsum, salt and phosphate.
In addition to mining, these machines can also carry out routing operations for the construction of mining service roads and railway tracks, the rehabilitation of roadways and installation of tunnel floors. The range of applications further includes the precise cutting of trenches and channels as well as surface leveling.
At this time, drilling and blasting was the main bauxite mining technique in use. The first is compact yet powerful, with a 2.

It is able to cut rock with unconfined compressive strengths of up to 50 MPa, ideal for medium-sized mining operations. The larger model, the SM, guarantees higher production rates and offers a cutting width of 2. Both models demonstrate their advantages in both productivity and product quality, guaranteeing lower production costs per ton compared to conventional mining. On average, 1. WIRTGEN surface miners, which are equipped with a discharge conveyor, minimize such climactic effects by cutting and crushing the material with a special cutting drum and placing it alongside the machine sidecasting ensuring constant productivity while minimizing the environmental impact.
The use of a surface miner also has a positive effect on water management in an opencast mine. The cut surfaces are leveled and can be cut at an angle. This further improves drainage and reduces water seepage into the ground. This protects most of the mined material from the rain and allows gravity to drain the piles.
The major cost factor in opencast mining is haulage. This increases the transport capacity of the entire truck fleet. Even the wear on tires, frame and suspension is reduced thanks to the quality of the roadways, also allowing the use of standard on-highway trucks. As a result, reduced transportation costs allow mining companies to achieve lower per-ton production costs.
Mine operators benefit from several cost reductions when using surface miners. For the mining companies, this translates into significant financial advantages for mining and processing. By using surface miners instead of drilling and blasting, raw materials can also be extracted effectively in the vicinity of residential areas, public roads, villages, rivers or other infrastructure e.
It is also possible to mine resources located in buffer and safety zones, maximizing bauxite yield within the concession area, generating significant additional revenue for the mine.Articulated type, fully hydraulic power steering with two double-acting cylinders.

The average human exerts 16 psi and that same person with snowshoes only exerts 1 psi. Now consider professional bicyclists, they use thin tires for riding on roads 90 psi but require wider tires for riding through grass and dirt 40 psi. As the surface area widens the ground pressure decreases. The same method can be used for construction equipment.
Wheeled vehicles tend to leave behind more environmental damage with an approximate 35 psi in comparison to crawler carriers which have been built with extremely low ground pressure measuring at only 5.
Therefore, it all comes down to weight distribution, and the facts say it all. A lb. For humans, low ground pressure allows people to walk in weather conditions that might not otherwise have allowed. For crawler carriers, lowering ground pressure allows units to work continuously through various types of terrain saving companies from down time. Additionally, low ground pressure of crawler carriers contributes to less environmental damage after major construction projects. This means less reclamation work after project completion.
So there you have it, ground pressure does matter for both humans and crawler carriers alike. Price, Inc. New Terramac Support. Why Does Ground Pressure Matter?Log In.

Related Projects. We're evaluating the effects of heavy construction equipment operating near the edge of earth slopes. We are attempting to model the vehicle loads and want to consider them as distributed loads per tire over the tire's contact area. Can we calculate contact area as load divided by tire pressure? Then, we would use the tire's section width or tread width as one dimension of the loaded area and the other dimension will be calculated from the contact area.
