Abstract:
The paper investigates the role of a protective gypsum pack left in the ceiling of chambers during a chamber-pillar system for the development of non-metallic deposits. There is an insufficient study of the issue during the development of sites with various fractures. The protective pack is considered as a key factor in waterproofing the treatment area from the Nizhnekazansky aquifers of the Bebyaevsky field. Studies have been conducted to establish the coefficients of structural weakening of the gypsum massif at the Bebyaevsky deposit, which are used in the proposed method for calculating safety pillars, taking into account the physical and mechanical properties of rocks and the depth of mining operations. Optimizing the thickness of the ceiling to 1.0 m depending on the fracturing of the array, it will allow additional extraction of up to 1610 m³ from one panel, which will significantly reduce losses without increasing production costs. This technique can be recommended for mining flooded gypsum deposits at depths up to 250 m.
Keywords:
