Planning experiment for laboratory tests on rock abrasivity
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2018, Vol 535, Issue 3
Abstract
The physical and mechanical properties of rocks (i.e., compressive strength, tensile strength, workability, or compactness) are often taken into account during the selection of a mining method and type of mining machine as well as the mining tools themselves. However, one of the main reasons for the abrasive wear of mining picks is the abrasiveness of rocks, which is seldom taken into consideration because there is lack of unambiguous and proven methods for its determination. The article presents the research plan and methodology, the stand for testing the abrasivity of rocks, the course of conducting preliminary tests as well as the statistical treatment of the results using the Statistica program, and determining the final values of the input variables in the basic research. The method has been developed taking into account rock abrasivity when selecting and forecasting the wear of mining tools.
