| Popis: | The article contains a method for determination of the energy capacity of face rock breaking by the knife operating element of the geokhod. In addition, the dependence of the breaking energy capacity on the pitch of the geokhod’s external propeller was revealed. The relevance of the study was considered. In order to set goals and objectives of the study, work features of new-class mining machines – geokhods and fundamental principles of geokhod technology were presented. Advantages and disadvantages of existing methods for determination of the energy capacity of rock breaking were identified, and the possibility of using them in calculation of power parameters of the geokhod’s knife operating element was assessed. Power and geometrical parameters of the geokhod’s knife operating element were determined, which affect the energy capacity of rock breaking. To determine the influence of the external propeller’s pitch on the breaking energy capacity, geometrical parameters of the knife operating element and parameters of mining conditions of workings were substantiated. As a result of the study, it was revealed that the energy capacity of rock breaking by the knife operating element decreases non-uniformly as the pitch of the external propeller increases. |
