Abstract:

The 670 ball is a geological barrier that will keep rotated rock blocks falling from the deformation zone of the Eynez shell and prevent the materials of the heilans that will form throughout the shell zone from coming to the coal production field. Soma-Eynez forms the falling block of the benefit and is composed of Neogenic old marns. The rocks of rocks in the 670 ball shelves, observed, threatened the safety of the mining work for the production of coal in the open tank. The maximum rotation distances of the rotating, falling and rotating stone parts at different shell heights are determined by using computer software. Considering the rounding distances calculated for different shell heights, the project mining limit of the open January coal operation has been determined. In this study, the reversal defeats observed in the 670-top were studied both kinematically and numerically, respectively, using stereographic projection and different computer programs. The security factors obtained from different software for the same shell geometry have been compared, the curvation angle of the broken surfaces and the effects of cohesion values on the security factor, which has caused turmoil defeat, have been studied. Additionally, the breakthrough breakthrough progress speeds from 20 deformation measurement points installed on the scratches that lead to rotation have been studied in time-related changes. The areas with the highest opening speed are associated with the areas where the bullet has been observed with a turning defeat.
