Reinforced Earth structure (back form) and the normal Reinforced Earth precast facing panels (front form) resists and deflects impact. Facing panels continue above the crash wall to the top of the structure, supported by typical high-adherence soil reinforcing strips and granular backfill, producing a Reinforced Earth wall from bottom to top.
The test results showed that the more angular fill gave higher pull-out resistance and friction values. The results provide information on the friction characteristics which can be used in the design of reinforced earth retaining walls using compacted coal wastes as the fill material.
Coal mining waste is a mixture of rocks associated with coal seams, mainly mudstones, siltstones, shales and sandstone, and its geotechnical characteristics may be compared to coarse-grained soils.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Key Words--Coal wastes, cost benefit, friction coefficient, minestone, polypropylene, pull out, reinforced earth, shear box. 1. Introduction Reinforced earth was introduced as a construction technique in civil engineering in 1966 and involves the amalgamation of reinforcing elements into a mass fill.
