Abstract

PURPOSE: To utilize the transferring capacity of a dump truck amply for a shorter working period by loading crushed stone into the dump truck with a belt loader at the foot of a stepped ground at the working face after they falls on the ground from a quarry at height.
CONSTITUTION: Crushed stone B falls on a stepped ground D with a bulldozer or the like along a slope surface C from the quarry at height A. A slant belt loader 1 is provided at a foot E' of a crushing working face E of a stepped ground D. An open trap 2 on the lower base end of a conveyor frame 5 inclined from the low base end to high base end of the loader 1 is arranged facing the foot E'. A crushed stone controlling section 17 is operated in an operation chamber 15 to place the crushed stone B onto a belt conveyor 5 and then, loaded onto a dump truck 18 at a high level of a machine 4. Earth and stone are quarried by this method.
