Abstract: The article provides diagrams of the nature of the loading of the rod by axial force. And also considered the advantages and disadvantages (cartridge, rotary and spindle) of the kinematic diagram of the rotary-feed mechanism (RPM) of the drilling rig. The formulas of the hardness of the drilled rock, the duration of the elementary cycle, the weight coefficients, the torque of the bit, the power of the PMM and the power of the compressor drive were determined.
Key words: Rod loading, weight coefficients, bit rotation torque, HPM power, compressor drive power, rotary feed mechanism, singlepass technology, maltipass technology.
