Abstract: In real terms the development of coal seams at greater depths, in the absence of stratified rock roof effectively backwater from the developed space, resulting in a sudden collapse of the roof rocks, the likelihood of blockage of mining increases. Having malleable support under such conditions attenuates shock effect and reduces the magnitude of stresses acting in the cross section of the beam to 30%. Tabbed array or pliable support eliminate negative phenomena that appear as a result of the sudden collapse of the wall rocks.
