Drilling rigs are one of the most primary equipment of the underground mining industry. Thanks to their application, it was possible to multiply several times obtained metal ore output generated in underground mines. For last several years, the research related to the development of special rigs predisposed to mine narrow vein deposits are conducted. Dynamic testing of one of such structures are discussed in the paper. The dynamic tests of the rig have been carried out in two ways - either as a real construction s...

Currently mobile mining machines, including primary ones, such as drilling and bolting rigs, or used in underground mining of metal ores, are most commonly driven by internal combustion engines. Due to the large depth of mining, this type of drive provides a number of disadvantages, including a large generation of fumes, heat and noise. The solution to this problem seems to be the use of the electrical battery drives, similarly as is the case in motor vehicles. The article presents the assumptions and boundary con...
