INNOVATIVE SOLUTIONS APPLIED IN TOOLS FOR DETERMINING COAL MECHANICAL PROPRERTIES

Abstract

Due to very specific conditions of work of machines and equipment used in coal mining industry, the manner of their selection, taking into account the changing working conditions, is very important. Appropriate selection influences the increased durability and reliability of machines and equipment, which translates into the economic effects achieved. As the issue of measurement and evaluation of coal mechanical properties (including coal workability measurement) is of great importance, previously applied methods for coal workability evaluation have been shortly reviewed. The im-portance of the problem is confirmed by the number of methods developed in various research centres all over the world. The article presents new instruments for determining and evaluating the mechanical properties of coal material (workability). The instruments have been developed in Poland and the author of this article is their co-inventor. The construction, principle of operation and innovative character of solutions applied in the instruments have been presented.
