Abstract
Boundaries of open pits are the most important parameter of open-cast mining of deposits, methods of determination of which, unfortunately, are still not correct enough, which negatively affects the efficiency of open-cast mining. The Department of Open-Cast Mining and Rock Destruction conducts continuous research on the development and improvement of methods for establishing the final contours of pits, approving the results in the design studies of specific deposits. The last object of the research was the iron ore deposit Kurkenpakhk of AO Olkon, which is currently not exploited. In the course of the research there was a doubt in the expediency of using the traditional method of levelling the bottom of the pit. The authors propose a new method of levelling the bottom of the pit.
