Karamushka O. The structural criteria of location of the dislocated zones in the coal layers of Donbas

Dissertation is devoted establishment of quality and quantitative laws governing a structural transformations of coal and their connection with dislocation of coal layers. On the basis of establishment of laws governing a structural transformations of coal in the dislocated zones of coal layers by an optical method - forming of coaljointings geometrically regular shape in the zones of tectonic dislocations, the method of location of the dislocated zones on the structure parameters of coalis developed. The methods of determination of intensity of zones of dislocation in coal layers and zonules in dislocations of coal layers are developed for the estimation of degree of dislocation of the selected zones in coal layers. The method of leadthrough of thermal researches of coal is improved in obedience to which as an inert matter a quartz sand is used. Application of sand does not influence on character of flowing of process of heating of coal sample and at the same time hinders penetration of atmospheric air to coal, formation of fire in crucible and contamination of space around holder of tests, that allows to get reliable and reliable derivatogrames of coal samples. Diminishing of intensity of the left (low temperature) part of exotherm on the curves of DTA of coal samples (after displacement aside of higher temperatures of a maximum of exotherm in the interval of temperatures 20-530 °С), which are selected from the dislocated zones of coal layers is set by a thermal method at quality level.
