Developing three-dimensional geological and economical models of deposits in combination with deposit economical values calculations, represent fundament for application of contemporary methods in the mining engineering. It is proved that contemporary methods, such are Lerchs-Grossman's method, Method of floating cone and Dynamic programming, are excellent models for generating the algorithm for contour optimization of an open pit mine. The exploration of the optimal pit contour can be relatively simple and fast process if specialized mining software are utilized. The simplicity, quickness and reliable results offer a wide range of contemporary methods applications built-in in many mining computing programs. Based on available contemporary methods and their elementary criterias (optimality, stability and slope stability), authors suggest an innovative method of open pit contour optimization, named Floating Slopes Method (FSM). This paper presents synthesis of results of FSM application on the coal deposit Kongora.
