LABORATORY STAND TESTS OF MINING ASYMMETRICAL DISC TOOLS
Abstract
The article presents the results of asymmetrical disk tools laboratory tests. This type of mining tools can be used for mechanical mining of hard rocks, among others in the solution of innovative roadheader head, presented on SGEM conference in 2016. The study was conducted at a dedicated laboratory stand, with an installed drive power of 80 kW. Stand consists of rotating rock sample, mined by special plate equipped with asymmetrical disk tools. The rock is mined using undercutting technique, also known as Wohlemyer method, after the name of its Austrian researcher. During research six components of the load acting on the disc plate were measured; in addition to this, thermographic observations were conducted. Tools have been tested in both qualitative and quantitative ways. Qualitative research consisted of disc measurement using 3D scan both before and after the mining test. After comparison of the corresponding three-dimensional images of discs and performing measurements with the appropriate computer software, image of individual tools wear were obtained. The results of quantitative research were based on gravimetric measurements of disks before and after the tests. The findings from conducted research may help in selection of the optimal tool for mechanical hard rock mining using undercutting, as well as to make estimates of the sustainability of individual disc tools.
