PNEUMATIC SHOCK ABSORBER FOR DRILLING MACHINES<\/h2>\n\n\n\n

Abstract.<\/strong> This paper investigates the wear of drilling equipment during drilling in hard and ultra-hard rock formations. Special attention is given to the reactive forces exerted by the rock mass on the drilling tool, drill rods, and the drilling machine. The literature review analyzes existing types of drill string shock absorbers intended for damping longitudinal, torsional, and combined vibration modes, and identifies their operational features and inherent limitations. It is demonstrated that vibration transmission along the drill string during hard rock drilling cannot be effectively mitigated by downhole shock absorbers. A pneumatic approach to mechanical vibration damping is proposed. The physical and mathematical models of the damping process are presented, together with calculations of the reduction in the maximum amplitude of longitudinal vibrations, illustrated using a standard drilling machine as a case study. A novel technical solution is introduced in the form of a pneumatic shock absorber capable of simultaneously attenuating longitudinal and torsional drill string vibrations while transmitting axial load and torque. A conceptual design of the pneumatic drill string shock absorber is developed, including sectional and cross-sectional views, and its structure and operating principle are described. The results demonstrate that the proposed pneumatic shock absorber provides effective protection for the drilling machine, drill rods, and drilling tool. The conclusions highlight that the developed solution significantly reduces the impact of drill string vibrations on drilling equipment and offers a measurable economic benefit by lowering the overall cost of mineral extraction.<\/p>\n\n\n\n
