Tensar® mechanically stabilised layers can provide the required performance for working platforms necessary in the surface mining industry. Case Study: Lee Moor Crushing Plant, Plymouth, UK TensarTech TR2 steel mesh panel system at Lee Moor Crushing Plant offered considerable savings over a concrete faced alternative.
Geosynthetics are synthetic products used to stabilize terrain. They are generally polymeric products used to solve civil engineering problems. This includes eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geo, geocells and polymeric nature of the products makes them suitable for use in the ground where .
The polypropylene geogrids are either extruded or punched sheet drawn, and polyethylene geogrids are exclusively punched sheet drawn. Figure shows a number of typical geogrid products. Although geogrids are used primarily for reinforcement, some products are used for asphalt overlay

Proven Solutions and Technologies for Mining Applications tensar international corporation (tensar) is the leading developer and manufacturer of highperformance products and engineered solutions for earthwork challenges in the mining industry. We satisfy customer needs and exceed expectations by providing a wide range of geosynthetic
Geogrids with tensile strengths up to 800kN/m place the highest demands on material and machine. Only through the use of highperformance fibres can the highest tensile strengths be achieved at low elongation, even with grid structures. The main field of application here is mining.
Tensar RE uniaxial geogrids are used for soil reinforcement in the construction of retaining walls and bridge abutment typically using Keystone TW3 modular blocks or concrete panel wall facing. Tensar RE uniaxial geogrids are also used in slip repair and construction of green slopes having either a wraparound construction or with the Green Terramesh system.
Underground mining is a distinct segment of the mining sector, with coal and other minerals being extracted from depth for processing. Being underground demands high safety considerations from strata control, and the maintenance of underground road networks is undertaken in confined spaces.

Geogrids Geogrids are made from connected ribs that intersect at right angles in regular intervals, creating openings that enable the geogrids to interlock with surrounding soil, stone, or other material. Geogrids are usually made by extruding, punching, or stretching plastics most commonly HDPE or polypropylene in one or two directions.

This proves the application of geogrids in improving the stability of coal mine waste dumps. Thus by using geogrids, higher dumps, accommodating large overburden, can be designed. The coal mining industry will certainly be relieved from the problem of land acquisition, which 1.
Types of Geogrids Based on the manufacturing process, there are three types of geogrids—Extruded Geogrid, Woven Geogrid, and Bonded Geogrid. Based on which direction the stretching is done during manufacture, geogrids are classified as Uniaxial geogrids and Biaxial Geogrids [7] as shown in Fig. 3.
