Abstract

The minable seam «Verkhny» within the Barentsburg coal deposit is geodynamically hazardous, its geodynamic phenomena manifest itself in the form of proper rock bursts,  shocks in the marginal zones and dynamic faults of  ground. Due to rockburst-hazardous situation the application of the areal relief of rock mass with transition to technological variants of mining with leaving the extended rib pillars at the boundary with the mined-out space, with their cutting by drivage of additional working is applied. Consideration  is  given  to the recommended  variants of pillar leaving  with  the data  of their assignment and applicability to geological-and-mining conditions of mine field sections. Description is given to the calculation of pillar sizes and parameters used for their calculations. Some examples are given of pillar leaving at different sections of mine field with geometrical parameters as well as the information is given on the seam extraction with prospecting  routes (paths) with leaving the support rib and barrier pillars. The leaving of safety support and barrier pillars with substantiation of their sizes is recommended as the method for providing the safe condition  of mining the «Verkhny» coal seam
