Abstract
Способ открыто-подземной разработки пологого угольного пласта средней мощности, включающий ведение вскрышных работ и выемку части пласта, выходящую под наносы, карьером с формированием уступов, проведение выемочных камер по технологии глубокой разработки угольных пластов с уступа борта карьера, подготовку запасов проведением штреков и выемку угля средствами механизации подземных работ, отличающийся тем, что кровлю выемочной камеры крепят крепью подготовительных выработок, расстояние между выемочными камерами принимают в три-четыре раза больше ширины камеры, в зависимости от прочностных характеристик угольного и породного массивов, уголь междукамерного целика частично вынимают проходческо-очистным комбайном в диагональных заходках, ориентированных под углом 120-135° к оси выемочной камеры и расположенных в шахматном порядке, длину заходки принимают не более длины комбайна, а транспорт отбитого в заходках угля по выемочной камере осуществляют самоходным вагоном.A method of open-underground mining of a shallow coal seam of medium power, including overburden operations and excavation of a part of the seam going out under sediments, a quarry with the formation of ledges, excavation chambers using the technology of deep development of coal seams from the ledge of the quarry, preparation of reserves by drifts and coal mining mechanization of underground work, characterized in that the roof of the extraction chamber is secured by the support of the preparatory workings, the distance between the extraction chambers is taken in three to four times the width of the chamber, depending on the strength characteristics of the coal and rock massifs, the coal of the interchamber pillar is partially removed by a tunneling and treatment combine in diagonal feedthroughs oriented at an angle of 120-135 ° to the axis of the extraction chamber and arranged in a checkerboard pattern, the length of the feedthrough is no more than the length of the combine, and the transport of coal beaten off in the openings through the extraction chamber is carried out by a self-propelled wagon.
