Abstract

"The use of power drawn scrapers, often called "slushing", for the moving of ore, stops filling, and waste rock has become standard practice in many mining operations. Several types of scrapers have been developed by practical application or by trial and error methods. However, a direct comparison of these scraper types under identical conditions has not been noted in a review of literature on the subject of mechanical loading. Written inquiries to authorities on scraping practice have brought replies that no previous comparisons of scraper types on a modal scale have been attempted. Therefore, the following thesis problem was set up: Purpose of Problem. The principal purpose of the thesis study of bottomless scraper scoops or buckets is to determine the comparable efficiency and applicability of the several types now in use as applied to different classes of earth and rock materials. It is hoped that these tests may form the basis for improved scraper design"--Introduction, page 1.
