     in an unsupported stope, rock mass caving can happen when the undercut is developed over a sufficient area. several parameters such as induced stresses, rock mass strength and geometry and strength of rock discontinuity influence rock cavability mechanism. this paper describes a new approach for understanding and estimating geometry of rock blocks created by the planar discontinuities in a rock mass. this algorithm is able to trace and identify all kind of blocks including convex and concave blocks formed by limited or unlimited fractures. using square matrices with integer elements and performing edge/face regularization step, reduce the size of the necessary matrices due to elimination of unnecessary faces, edges and vertices. therefore speed and accuracy of block tracing operation will increase. the algorithm was programmed in c#.net by over 8100 code lines and some cases were modeled by the code as example.
