MECHANICAL SUPPORT FOR THE ELIMINATION OF THE CONSEQUENCES OF ACCIDENTS IN UNDERGROUND MINING

. One of the urgent tasks for rescuers is the prompt elimination of the consequences of collapses in mine workings in order to save miners and restore the normal functioning of the mining enterprise. The article discusses the issues of improving the efficiency of emergency rescue operations in underground mine workings, taking into account the possibility of maximizing the time period of isolation of victims as a result of various roof rock collapses. The authors have reviewed the designs of various mechanical devices to facilitate the dismantling of blockages, the movement of heavy loads by rescuers along vertical and inclined workings. As a technical device that provides effective protection of rescuers from roof collapse during the analysis of blockages in underground mine workings, it is proposed to use a mechanical prefabricated modular type fastener consisting of a mechanical module – a support-enclosing type device, a module for rolling back rock during the analysis of blockages, as well as an emergency communication module. To perform the work, the authors used methods of physical modeling and prototyping of a future device sample implemented in its design; experiments in the form of laboratory tests. The authors concluded that the use of a mechanical prefabricated module in the analysis of blockages provides constant support for the roof, which reduces the risk of its collapse, creating a safe workspace for soldiers of paramilitary mountain rescue units.
