Reseach Old Rubber Tires Utilization to Increase the Life of Support in the Longwall at Quang Ninh Vietnam

Abstract

In longwall mining where use frame support and control roof by full caving; rocks could impact the support, damage some its details and reduce support’s longevity. Using waste, elastic, and deformable capability materials (like old truck tires) not only reduce impulse which impact the support fatally and increase support’s longevity, but also contribute to protect the environment.
