| The analysis of mining-induced sinkholes occurrence is a very important
issue as far as the spatial development optimization is concerned.
Research conducted for this paper was focussed on examining the
applicability of GIS and the associated AHP method (analytic hierarchy
process) for estimating the risk of discontinuous deformation occurrence on
the surface. Qualitative factors were accounted for in the sinkhole risk
assessment, thus creating bases for the research. These elements play an
important role in the process of sinkholes formation; however, they were not
used in prediction models. Another assumption lay in minimizing the number
of variables in the model. Accordingly, the most important qualitative and
quantitative risk factors were finally selected on the basis of whether the
risk of cave-ins occurrence on the surface could be calculated. The results
of the estimation of potential sinkhole zones were verified. The locations
of actual and high-risk potential discontinuous deformation were compared.
The congruence between predicted values and the actual observations of sinkholes
was very high. The results of research presented prove the necessity to
evaluate sinkhole hazards in view of qualitative factors. |
