To the problem of improvement the working tools of mining excavation machines

The mining working tool used to separate the rock from the massif in the processes of mining, mining, crushing of rocks and processing of stone, has passed a long way of development. For hundreds of thousands of years, its changes have been slow, barely noticeable, and only in the last two centuries has the intensity of its development sharply accelerated, especially in the last 50−80 years. The article presents an analysis of the features of the stages of development of mining tools. It is noted that with each stage of the development of mining tools, executive bodies, mining machines and technological processes of mining production are being improved, the intensity of mining operations is increasing. The regularities of the process of development of the working tool, which led to the appearance of modern chisels of cutting machines, as well as the evolution of requirements for materials, structure and design of cutters, are considered. The role of the working tool in the development of mining machines and in the technical progress of the mining industry is noted. The main and auxiliary quality features that were characteristic of the mining tool at different stages of its development are highlighted. The requirements for the quality of the process of separating coal from the array and to the cutters of modern miningexcavating machines are formulated.The direction of development of the cutting tool at the present stage is shown.

Keywords: mining tool, improvement, cutter, executive body, mining excavation machine, efficiency, wear resistance, reliability.
