ABSTRACT
In the case of the process of mechanical disintegration of mineral raw materials, the supply of a certain amount of energy, which is consumed for the separation of rock chips (elementary pieces) from the rock mass, is required. By this process, the entire cycle of mining of the economic mineral is given. The minimum energy demand of the disintegration process is achieved especially through the correct selection of a tool and the selection of optimum cutting speed and rate of tool advance into the cut, and also other parameters that have a minor impact on the very disintegration process. For the determination of optimum parameters of mining machines, a sophisticated instrument for the in-situ measurement of disintegrating forces can be used. The instrument is ATEX certified for use in a potentially methane explosive atmosphere, and thus can be used in all mines not only in the Czech Republic but also practically all over the world. The principle of the instrument consists in the in situ measurement of disintegrating forces and then the application of them to a specific machine or a mining organ.
