Abstract
On the example of Starobinskoye deposit the criteria determining the choice of development systems and possible ways to increase the extraction of potassium reservoirs are considered. Different principal schemes of sylvinite extraction from pillars by auger drilling technology are proposed. The method of geomechanical justification of the parameters of pillar extraction is developed. The results of the estimation of the stress-strain state (STS) of pillars and their host massif for the characteristic time moments of the pillar delineation of mined-out spaces are given.
