Abstract
Abstract
The article presents problems related to the mining of compact and very hard rocks with cutting tools, mainly with tangential-rotary picks. The currently used disc tools, their parameters and the way of working are described. The disadvantages of selected solutions and related obstacles to their wider use in mining have been presented. The directions of further development of disk tools were presented, allowing their use, for example, in mining heads of longwall shearers and roadheaders.
