Heap spreading process for coal waste tips - uses waste carrying goods vehicle with central funnel outlet to spread waste which is then rolled, graded and compacted

摘要

The waste heap is made of granular and bulk material especially used for waste obtained in coal mining. The material is tipped by larged goods vehicles fitted with a floor pouring outlet system with the waste bulk goods being spread during the good vehicle movement. The object is to spread the material horizontally making an almost level surface (2) with a subsequent grading and rolling process being carried out by appropriate equipment. At a later stage the new even surface is compacted. The outlet system of the bulk goods carrying vehicle consists of rectangular shaped funnel.
