Abstract

A method for the scraping operation of a coal seam of considerable thickness, by means of a scraper driven on a conveyor that is automatically inserted in front of the coal front, characterized in that for the time being the upper parts are extracted exclusively and, if necessary, also the central parts of the coal. reef, thereby forming an inclined sliding surface directed towards the conveyor in several successive passes of the scraper, and because after this, in turn in several successive passes of the scraper, is when the central and lower parts of the reef are removed, that have remained standing, until arriving at the lying one, loading all of them in the transporter.
