Abstract: The article discusses current issues of the development and improvement of geohod maneuvering systems, a class of mining equipment designed to form underground workings through complex rotational and translational motion in a rock mass. Unlike traditional tunneling shields and combine harvesters, geohunks require fundamentally different technical solutions to ensure the necessary maneuverability. The analysis of existing design solutions to increase the maneuverability of tunneling shields and their applicability to geohopping technology is carried out. Various types of executive bodies (IO) and their influence on the maneuverability characteristics of geohouses are being investigated. Special attention is paid to the problem of creating curved channels of increased width, necessary for effective maneuvering of a geohod in a rock mass. Various design schemes of IO, including rotary, drum and crown types, as well as methods of their modification to increase the width of the gripper are considered. Different variations of the statutory executive organs (ZIO) such as disc and crown are considered. The authors identify the key factors determining the relevance of research in the field of increasing the maneuverability of geohouses: the need to master difficult geological conditions, increase the safety and productivity of underground work, as well as the development of new mining technologies. The necessity of developing innovative technical solutions to improve the mechanisms of maneuvering geohouses is substantiated. The paper presents the results of an analysis of various ways to create a widening of the workings for maneuvering, including changing the angle of installation of the drums, their axial extension and adjusting the axial distance. The data obtained can be used in the design of new samples of geohopping equipment and improvement of existing structures.
