Among all indicators, only the ratio of the length of the lava to the depth of development has a noticeable connection with the deviation of subsidence. Using mining and geometric analysis, the coefficient of dependence of the deviation of subsidence on the length of the lava was established, which is proposed to be taken into account in the design of the fake for conditions when the ratio of the length of the lava to the depth of development is in the range of 0.1-0.7.
