где Кпод - коэффициент податливости крепи, доли единицы;
ε - относительная деформация упругого сжатия для материала блока, доли единицы;
m - мощность пласта, м;
Кр - коэффициент остаточного разрыхления материала блока, доля единицы;
R - радиус выемки в элементе блока, м,
с возможностью возведения охранной полосы требуемой податливости для заданной мощности пласта.The support for the protection of the preparatory workings, made in the form of a guard strip, consisting of separate blocks laid on each other by the working parties, characterized in that each block is made up of two identical elements, one of the sides of each element being a working one, is a flat surface and the other side, opposite to this working side, is made in the form of a relief surface having semicircular notches in cross section, oriented perpendicular to one of the pairs of side sides of the block element and about spaced from each other at a distance equal to the diameter of the recess, with the formation of protrusions between the said recesses, and the extreme recesses of the block element are made with a cross section equal to half the cross section of each of the recesses located between these extreme recesses, while the elements in the block are aligned with each other, having recesses and protrusions so that the recesses of one element are coaxial with the protrusions of the other element with the possibility of engagement of the recess-protrusion during the manifestation of rock pressure and their subsequent movement in the direction perpendicular to the flat surface of the block elements, with the formation of a compliant connection that accepts the load from the side of the massif, and the number of blocks n b along the height of the guard strip is selected from the ratio
where K pod - lining compliance coefficient, unit fractions;
ε is the relative elastic compression strain for the block material, fractions of a unit;
m is the thickness of the reservoir, m;
To p - the coefficient of residual loosening of the material of the block, the proportion of units;
R is the radius of the recess in the block element, m,
with the possibility of erecting a guard strip of the required compliance for a given reservoir power.
