GEOCORD for roads in open-pit mines PRESTORUS

Geosynthetics in mining

According to the calculations made by the Promtransniiproekt Institute, the use of three-dimensional geocells for road construction will contribute to:

Improving the transport and operational qualities of quarry roads, reducing the cost of their maintenance and repair up to 25%
– Increasing the strength and evenness of the pavement

— Improved grip, no spillage
Up to 3% increase in speed and productivity of dump trucks
Up to 7% reduction in fuel consumption
Up to 15% reduction in costs of vehicle maintenance
Up to 18% increase in mileage for oversized tires

DESIGN ADVANTAGES

INCREASED PRODUCTIVITY OF SELF-PROPELLED EQUIPMENT

Increased speed of the machinery moving through excavations;
Reduced non-productive downtime associated with unscheduled equipment repairs and maintenance;
Less equipment required

REDUCED COSTS FOR MAINTENANCE OF SELF-PROPELLED EQUIPMENT

Reduced tire wear associated with uneven ground, watered areas and foreign objects on the route of the mine workings;
Reduced repair and maintenance costs for self-propelled equipment.

INCREASED TRAFFIC IN THE MINE

Increased throughput capacity of the mine, which allows for more efficient use of transport excavations and planning of logistics processes.

WORK STAGES

Design of a road in opencast mines

• non-woven geotextile GEOKNIT-N^® with a density of 400 g/m^® was used to separate layers of clay soils and aggregate material

• GEOCORD^® was installed over the geotextile

• local aggregate material (crushed stone with a particle size of up to 70 mm) was used to fill GEOCORD^®. To avoid deformations under load, the protective layer over the geocell was at least 50 mm.

What is GEOCORD^®?

GEOCORD^® is a three-dimensional geocell produced by welding polymer stripes in staggered order.

In contrast to traditional geosynthetics,
GEOCORD^®‘s polymeric tapes are reinforced with high-strength synthetic fibers, providing an additional margin of safety and resistance to cell deformation under high loads.

GEOCORD^® is transported to the construction site in compact modules on pallets or in bulk to minimize logistics costs.

When stretched the geocell module turns into a three-dimensional honeycomb structure of a large area which is laid on a horizontal surface and fixed with anchors.

Geocells can be filled with vegetative soil, sand, crushed stone or other aggregate material depending on the requirements of the project.

What Makes GEOCORD^® Unique?

The reinforcing threads give the geocell increased strength and resistance to deformation under constant dynamic loads.

In other words, a design with GEOCORD^® can withstand loads without deformation and last much longer. GEOCORD^® is protected by international patents and recognized worldwide.

FAST-LOCK^® is the fastest way to connect geocell sections.

Traditionally, the sections are fastened with a pneumatic stapler. As you know, safety requirements in mines do not always allow the use of pressurized equipment. The FAST-LOCK^® fastening key is installed manually with minimal effort, which optimizes the speed of installation of geocells by 50%. It’s very convenient!

We suggest using yellow-colored GEOCORD^® in yellow in low-light conditions of underground mines. The bright color of the geocells can help notice parts of the road where a protective layer of crushed stone is needed and prevent the destruction of the cells by the wheels of transport. This color can be achieved thanks to the highest quality raw materials and the use of special additives.

Tailor-made GEOCORD^® perforations and strip texturing increase the bond between the aggregate material and the three-dimensional geocell, improving structural performance and increasing the reinforcement effect of the composite layer.

Cell sizes and height of GEOCORD^® are selected individually based on the axial loads from the moving equipment and the traffic intensity on the site. The dimensions of the modules depend on the width of the passages in the mine.

The service life of GEOCORD^® is at least 100 years from the moment of its production, which is 50% longer than that of traditional unreinforced geocells.
