摘要：The article formulates a new concept for design of the steel angle headframes of the new system for state-of-the art mines. One of the important structural elements of the steel headframe is a rig, installed above mouth of the vertical shaft and designed for equipment and passage of mine conveyances in shaft. A traditional frame rig of rectangular section is the most cumbersome and heavy-weight part of the headframe due its load-bearing. The proposed by the author headframe of multifunctional purpose, that includes a non-load bearing rig of circular cross-section, will allow reducing load on mine mouth and forgoing the sub-frame that greatly simplifies the task of finding an optimal design solution for the structure. There is an analysis of the most significant factors that significantly affect formation of the main design parameters of the sheave wheels and the rig of the examined headframe. The proposed idea of the independently operating structural units, one of which is a circular rig, significantly reduces a number of controlled variables, with which a designer can vary designing a headframe.
