Burchakov, A. Perezhilov] Conclusions: 1. The technical parameters of coals of the grades K and K2 have been studied during working of the excavation pillar by eastern long-wall faces 4 and 5. 2. Statistical characteristics of variation series were obtained. 3. Maps of isolines representing the "principal relief forms” have been compiled, which describe the regularities of distribution of the technical parameters. 4. The variations of these parameters were examined in three directions relative to the axis of the well used for multiple hydraulic treatment of a predegassed seam.
