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...
- To gather, compile and evaluate information about current geophysical methods used for the characterization of the geological formations in respect to their diggability by surface coal-mining equipment and particularly by bucket-wheel excavators.
- To assess the capability of the most appropriate geophysical methods (derived from the previous review) in varying geological and mining conditions by performing field tests using conventional geophysical instrumentation in the coal-mines of the beneficiaries companies.
- To develop specialized hardware (based on existing geophysical instrumentation), installed on the bucket wheel slewing boom, and dedicated software for acquisition, transmission and processing of the obtained measurements.
- To build an expert system which can inform in advance the BWE operators for the occurrence of hard rock inclusions or difficult or even non-diggable geological formations. The reasoning of this expert system will be based on data obtained from the geophysical instrumentation installed on BWE, on visual inspection of the mine’s face and on existing experiential knowledge regarding mining with BWE.
- To develop method for decrease or even exclude the influence of abnormal impulse loads generated during exploitation of stones and large fractions of solid rocks.
