ACCOUNTING FOR THE EFFECT OF SANDSTONE AND LIMESTONE ON THE MAXIMUM SUBSIDENCE OF THE EARTH’S CRUST CAUSED BY MINING
The paper proposes to increase the accuracy of prediction of maximum subsidence of the earth’s crust according to the normative method by applying a corrective coefficient that takes into account the proportion of strong rock layers in the undermining mass and the ratio of width of the mined-out space to the mining depth.
