Research and Modeling of The Impact of The Development of Tselikov On the State of The Earth's Surface

Mining of reserves of ore deposits, represented mainly by gently falling stratiform ore deposits, is carried out, as a rule, by a chamber-pillar mining system. This system causes the formation of significant volumes of worked-out spaces in the bowels, which are retained by inter-chamber, barrier, and tape tselikas left in accordance with the technology. At the same time, the developed spaces are often represented by repeatedly overlapping sections, the terms of which can be counted in tens of years. Under the influence of mining operations, the pillars are often destroyed, which leads to the appearance of extensive areas of collapses and even sinkholes on the surface. If engineering communications, industrial and civil buildings and structures, and other infrastructure facilities are located on the surface in the zones of influence of mining operations, then the consequences of mining reserves can be critical for surface objects. At the same time, it is impossible not to take into account that ore temporarily written off in losses concentrated in the whole is, by definition, a very significant resource from the point of view of replenishing reserves of deposits. Therefore, studies related to the prediction of the consequences of mining stocks concentrated in the whole are very relevant. The methodology presented in the article, based on the finite element method, allows us to assess the consequences of repeated testing with a sufficient degree of reliability.
