One of the main challenges facing deep quarries today is ensuring the stability of the quarry board. The article considers the influence of natural and man-made factors of mining operations on the stability state of the quarry sides.To maintain the quarry side stability, the efficiency of mining operations and security work, the results have been presented using the program. When determining the results, the "VNIMI" method is used, which uses the algebraic sum of forces, as well as the "master" program with the addition of additional factors. The research was carried out on 4 characteristic profiles in the sides of the quarry using the VNIMI methodology and the multifunctional computer program "Ustoi", as well as the procedure for calculating the stability margin coefficient. The calculation results calculations show that with increasing the General angle of the side, the margin coefficient decreases, but the width of the collapse prism increases.Summing up, we can say that when calculating the stagnation of the Board, using the "master" program, the change in the stagnation reserve coefficient is given and it is recommended to adhere to it for quarry boards with a height of 500 meters and higher.
