INCREASING OF THE SERVICE LIFE OF BUCKETS WITH CORNER EDGES OF BUCKED-WHEEL EXCAVATORS IN THE LOCATION OF THE ČSA BROWN COAL SURFACE MINE

Original language description

In accordance with the latest trends, considerable emphasis is put on all mining companies in the Czech Republic not only on reducing the environmental impact of brown coal mining, but also on overall efficiency, the balance of which can be improved by increasing of the operational reliability of individual components of technological units and reducing operating costs. And it is the latter sphere, in that Vrsanska uhelna a.s. does considerable initiative. In cooperation with the firm RENOMAG s.r.o. and the Research Institute for Brown Coal a.s. carries out the development and laboratory and in situ operational tests of new types of buckets with corner edges and other material tests of disconnecting organs used in the extraction of brown coal by the surface method. The article briefly acquaints the reader with the progress of work on the development of new types of buckets with corner blades of a bucked-wheel excavator series KU 800 used for mining of the overburden at the site of the Czechoslovak Army mine (CSA) and its content follows a series of articles describing activities in the field for the monitored period within the solved project. Attention is paid mainly to the results of operational testing of new prototypes of blades on a real machine in the conditions of overburden mining at the Vrsany mine, based on other designs and modifications of replaceable corner blade were created, which were tested in real operation of CSA quarry. The new replaceable corner blade with an innovated shape and unique material composition was then used on the KU 800 excavator in order to verify the functionality of the edge geometry in specific operating conditions and to find out the appropriate edge geometry and abrasion protection for the given mining conditions. At the end of the article, the results and evaluation of the implemented long-term operational tests are described together with the final summary of specific benefits of deployed prototypes of buckets with corner edges.
