| Shrnutí: | Title screen The article describes a problem of increasing hydraulic backhoes performance on the open coal pits depending on the parameters ofdrilling and blasting operations. When developing coal-bearing zones of complex-structured coal deposits, due to the design features ofworking equipment, mobility and autonomy, hydraulic backhoe excavators are able to perform both mining and overburden operations moreefficiently than rope shovels. Hydraulic backhoe excavators are extracting machines with downward scooping, which determines theworking out of shotpile of the blasted rock in several layers. Therefore, the primary technological directions of increasing the efficiency ofbackhoes’ operations are the justification of parameters of drilling and blasting operations to ensure a rational degree of rock crushing andrational parameters of the face for maximum realisation of the design features of excavators. As a result of research, the specificconsumption of explosive and the diameter of explosive boreholes are among the most significant controlled technological factors that affectthe quality of rock crushing. The substantiation and practical application of rational technological parameters for hydraulic backhoes at theopen coal pits can provide higher technical and economic indicators on the backhoes application, compared to the rope shovels. Theresearch was based on the data from Kuzbass (Kemerovo region, Russia) coal deposits being developed by open pits. |
