Abstract: This article proposes a step-by-step algorithm for selecting the minimum permissible (optimal) width of the interpillar pillar when mining the IV-th sylvinite layer when applying the technological scheme of layer excavation of the Third Potash horizon with sequential mining of layers in areas with a stable direct roof and possible re-use of the transport drifts of the faces. The development system scheme is proposed. The technological schemes of preparation and mining of potassium formations for the Starobinskoye deposit are schemes that include the maximum possible extraction of reserves from the subsurface, solving simultaneously the problem of dynamic roof collapse, ensuring a minimum amount of mining preparation work with good stability of preparatory workings and face space, high rates of ore quality and productivity of mechanized complexes.
