Method for open-pit development of mineral beds includes fan development of pit field with trapeze-like cuts with respect to turn point placed outside the pit, transportation of rock mass by pit communications along terraces, with following transportation of rock mass by connection communications, with reloading to transport communications in capital trenches and transportation by those communications to the surface of the pit. In the boundaries of the pit one forms additional turn point, this is connected to the stationary unloading point of rock mass reloading, at that the pie displacement of connection communications is performed with respect to additional turn point.
