Essay

This work is based on the first time established geomechanical parameters for the geological conditions of the mine "Stepnaya" DTEK "Pavlogradugol" taking into account preliminary constructed disassembly chamber. In the thesis solved the actual scientific and technical task of determining the disassembly chamber support parameters. The failure zones sizes in the chamber roof and the load on its roof support at the time of pairing the chamber with the working longwall face are estimated. Based on field measurements of rock mass deformation with deep frames it is set the regularity of geomechanical processes when approaching wave bearing pressure in a pre-built disassembling chamber and the distance of cleaning work's exposure on the state of disassembling chamber is defined. The shape and size of the zone of destruction, that appears over the worked out space of longwall and the disassembling chamber are determined. The loads on the support, due to the redistribution of stresses before moving londwall face in relation to the distance between them and the landing step of the cyclic subsidence of the main roof are defined. Economic efficiency of disassembly chamber's pre-construction for reducing operating time of assembling and disassembling works equals to 7.59 million UAH per working face. Keywords: disassembly chamber, support parameters, longwall face, rock failure zone, plow complex.
