Popis:	This paper describes a new approach to the problem of defining geometrically polyhedral rock blocks created by the intersection of planar discontinuous in a rock mass. The approach represents an extension of the combinatorial topology concepts to solid geometry, which, when implemented computationally, results in a procedure for the systematic identification of the spatial arrangement of rock blocks. The principle of simplicial homology is reviewed and a specific application of block geometry analysis is presented. Various formulae are shown to be necessary in the derivation of the block identification algorithm. The simplicity of the procedure makes it very attractive.
