Optimal adaptation of currently exploited and new bucket-wheel excavators for mining of overburden including interlayers with excessive mining resistance and unmineable inclusions...
Monitoring system of bucket wheel excavator load carrying structure efforts and method of diagnostic signals analysis for current assessment of threats of load carrying structure damages as well as constant control...
Real-time mine-face inspection system, based on geophysical methods, capable to detect hard rock inclusions and geological formations which are difficult to be excavated by bucket-wheel excavators...
- Define requirements concerning mining system enabling decrease of amplitude for all kinds of dynamic loads.
- Determine, on the basis of real excavators, values of maximal stresses in load carrying structure resulting from impulse loads during exploitation of structures with unmineable inclusions as well as coefficient of stresses resulting from mass vibrations in function of properties, included in exploited structure with excessive mining resistance.
- Develop a method of definition of computational substitute strength enabling proper analysis of impulse loads arising when a bucket encounters unmineable inclusions.
