FIELD: mining.
SUBSTANCE: proposed plant comprises mobile running gear and drive hardware not including the ICE. Drive hardware comprises drive motor, elements to transfer power between drive motor and drive wheel, electrical system, pressurised working fluid system, jib moving along running gear and equipped with rock drilling machine and control unit. Control unit incorporates systems control algorithm. Drive motor serves as the generator and the main brake at long-term motion over the slope. Control unit can control electrical system and electric power generated at downslope motion for charging of storage battery. Proposed method consists in plant braking at long-term motion over the slope by drive motor solely. Storage battery is charged. Electric power is converted to pressure energy in response to demand in excess power, increasing the plant maximum speed at downslope motion.
EFFECT: efficient distribution of electric power at downslope motion.
