Functional structure of battery drive for self-propelled mining rig used in room-pillar ore exploitation system

The article presents the structure of the battery drive of a self-propelled mining vehicle on the example of a drilling rig, used in the room-pillar system of copper ore exploitation. Such solutions, due to the ore mining in increasingly difficult operating conditions, are becoming more and more popular in the world. The main assumptions required for the synthesis of this type of drive were indicated, as well as the adopted structure of such a solution was described. The selection of the appropriate drive structure determines the final work characteristics of the self-propelled mining vehicle, and thus the actual suitability of such a machine for use in mining conditions. The paper also details the main technological advantages of this type of drive over classic internal combustion drives

Drilling and bolting rigs operator support using FGS (Feeder Guiding System) and remote control

The article presents the assumptions and main functionalities of two operator support systems - the FGS (Feeder Guiding System) and the remote control system of a drilling or bolting rig. Both of these systems greatly facilitate the work of an operator of a self-propelled mining vehicle in the conditions of an underground metal ore mine. The first of the described system allows for real-time control of the current position of the mining boom and facilitates the drilling of blast holes according to a predetermined drilling pattern. The second of the systems - a remote control system - is used especially in conditions of unstable rock mass or in the case of work in particularly difficult operating conditions, where it is advisable to limit the presence of the crew from the face-up to the necessary minimum. The intensity of these vibrations was related to the conditions of the cutting process
