1.Methods
In order to increase the efficiency of the operation of the CFP at the coal mine during the extraction of solid overburden rocks, its main structures have been extensively analyzed. As a result of the analysis of the process of operation of the central processing unit, it was revealed that one of the main reasons for stopping the main conveyor as a result of its rush lies in the peculiarities of the mechanism of operation of the unloading and loading hopper of the central processing unit. Based on this, we have studied in detail the process of operation of the unloading and loading hopper of the CFT using the “Ansys” program.
The ANSYS software package allows the calculation of metal structures by the finite element method. The ANSYS program also optimizes design developments, which is a computer technology consisting of selecting the optimal project from several using finite element analysis. The designer selects the criteria and constraints of the project and creates the same parametric model as in parametric design (fig.2). The optimization procedure controls the execution of the analysis based on the decision on the values of the parameters used in the trial calculations [8,9].

The program “Ansys” was used as the main method of analysis due to the fact that this program made it possible to carry out the most accurate mathematical calculations of geometric parameters of this design. The program "Ansys", along with other programs "Solidworks", Nx and Compas, is successfully used in solving engineering problems. With the help of the program “Ansys Workbench” on the basis of precise geometric parameters, we have constructed 3d models of the unloading and loading hopper of the CFT located between the conveyor lines [10-12]. The analysis of the constructed 3d models of the unloading and loading hopper allowed us to determine the causes of the burst of the main belt of the Central processing unit. So, in particular, with the help of graphical and mathematical calculations, it was found that such indicators as: the height of the unloading and loading hopper of the CFT and directly the geometric parameters of the structure itself play an important role. In order to analyze the strength of the dynamic stress of the fall of solid rocks, calculations were carried out using one of the types of the program “Ansys Workbench” (Explictdyunamic)[13-15].
