METHOD OF STEERING CONTROL OF WORKING ELEMENT FOR HOLE MAKING IN QUICK GROUNDS AND MARSHY GROUNDS

摘要

FIELD: mining.SUBSTANCE: method of steering control of the working element for hole making in quick grounds and marshy grounds comprises immersing or rising the working element in case of deviation from the trajectory. At that the immersing or rising the working element is carried out by changing its weight. When emersion of the working element its weight is increased by supplying filler in the adjusting chamber of the working element. While immersing the working element as it moves the weight of the working element is decreased by removing a part of the filler from the said chamber of the working element.EFFECT: immersion or emersion of the working element in the ground.2 cl, 1 dwg
