An ever growing application of ripping techniques in surface mining is due to economic factors and significantly stricter environmental and social regulations which restrict drilling and blasting operations. Surface miners and milling machines would be the most efficient machinery for explosive-free mining. As an open pit is mined out and the haul distances increase, it becomes reasonable to use a combined conveying system comprising different conveyor structures. This article describes an enhanced conveying technology involving milling machines, wheel scrapers, and conveyors. A milling machine rips rock and sends it to an open trench. A wheel scraper which follows the milling machine picks up the ripped rock from the trench. Wheel scrapers do all the loading and conveying and require no auxiliary equipment, thus increasing the mining efficiency. In this technology wheel scrapers perform a collecting and conveying job delivering rock from the pit to a receiver bin of the main conveyor. The proposed design of a wheel scraper includes a feed chute and a scraper used as a loading aid to help extract small pieces of loose rock. A feed chute helps convey rock to the shovel of a wheel scraper. Once the front area of the shovel is filled up with rock, a scraper activates moving rock to the rear area of the shovel. The enhanced mining technology will help reduce the extraction and conveying costs and thus improve overall mining efficiency.
