Planning and optimisation of mining operations based on the interpretation of geological data and their automatic processing during mining operations
The research project focussed on predicting the composition of several coal seams currently being worked in different coal faces, within two neighbouring collieries of the Campine coal field. The prediction is based on the interpretation of computer-processed geological data collected from the colliery archives or obtained during mining operations. Several procedures of "Star Topographic" have been reprogrammed and a geological database has been specially designed for the Campine colliery data. This database contains different kinds of files, the processing of which allowed different applications such as mapping, and bed-by-bed lithological studies as well as lithostratigraphical correlations. The different computer-generated graphic documents have been evaluated for their use as predictive tools and several applications to coal mining are given. The digitising of the different mine maps allows automatic reproduction at different scales, thus providing a considerable saving of time for the mine surveyors. Handwritten data from the mine surveyors' notebooks can easily be input and automatically processed through contouring routines into isopach maps. The latter can be extrapolated into unknown or poorly explored working areas, allowing the prediction of targetted coal seam thicknesses.
