Abstract: Discontinuities have an important influence on deformation and failure of rock mass in practical engineering. It is one of the key issues in modern rock mechanics to investigate geometric characteristics of joints and fractures inside the rock mass such as shape, size, location and direction etc. Based on the deep analysis of the above geometric properties, it is proposed that the stochastic fractures in the rock mass can be simulated with the random numbers generated by the Monte Carlo method. The related algorithm is designed and implemented. The correctness and effectiveness of the algorithm is verified with an example of a project. This will lay a solid foundation to further study the cutting problems of discontinuous rock block systems.

Abstract: In this paper the main factors of impacting the quality in cutting the plate between the Shear blade clearance adjustment and control were analyzed, Focused on further analyzing all relevant factors on adjusting the Shear blade clearance , combined with the accumulated process parameters in production of Thick Steel Plate Plant of He Bei Wen Feng Iron and Steel Co., Ltd. Proposed for the first time the mathematical models of the best adjusting of Shear blade clearance of disk shear in cutting plate.
