On the issue of protecting structures from the harmful effects of underground mining in coal and shale deposits with an unexplored nature of rock movement
Abstract
Until now, at newly developed deposits and at operating deposits with an unexplored nature of rock movement, the calculation of safety pillars in accordance with the recommendation of the "Rules for the Technical Operation of Mines" was carried out by analogy with other more or less studied deposits. However, there were no instructions on the selection of analog deposits, which could not but lead to an incorrect choice of parameters for calculating safety pillars. At present, it seems possible to give some guidelines on the selection of analog deposits based on accumulated factual data. These instructions can be used in calculating pillars during the design of mines and at operating deposits with an unexplored nature of rock movement. They can also be useful in calculating the profile lines of observation stations.
