摘要

reveal the solution, in which oil is cut and fastened on the pillars of the technological chamber whose dimensions decreases successively to the dimensions of the pillars of the residual.way is characterized by the fact that in the environment of calizny (6) leaves on both sides of the at least two rows of pillars of technology (7), and another at least one row are the pillars of technology (8) whose size is reduced about 50%, while the remaining pillars technolog iczne takes to the dimensions of residual pillars (5).
