Abstract: The energy intensity of rock destruction is the main indicator for evaluating the geometric and power parameters of the executive body of a mining machine. The existing methodology for calculating the knife executive body of the geohod does not take this indicator into account. The purpose of the work is to develop a methodology for determining the energy intensity of rock destruction during the formation of a cavity in the underground space by the executive organ of the geohod for the destruction of rocks of small strength. A substantiated choice of the method for determining the energy intensity of rock destruction and the possibility of applying it to the conditions and requirements of the geo-locomotive technology for forming a cavity in the underground space at shallow depths has been made. Based on the developed methodology for determining the energy intensity of rock destruction by a knife executive body of the geokhod, a calculation algorithm and a computer program have been developed. This made it possible to obtain the dependences of the influence of the geometric parameters of the external mover and the executive organ of the geohod on the energy intensity of the destruction of the rock. As a result of the study, it was found that the energy intensity of rock destruction by a knife executive body, designed to destroy rocks of a small fortress, varies unevenly when the geometric parameters of the external mover and the executive body are changed.
