Abstract

Бесцеликовый способ выработки угольных пластов, включающий продвижение блока очистных забоев по простиранию пласта, как в сплошной системе разработки, отличается тем, что охранные целики не оставляются, очистные забои собраны в блок и расположены на прямой линии, порода от проходки подготовительных выработок на поверхность не транспортируется, а размещается в выработанное лавами пространство, посадка кровли происходит без зависания на целиках, равномерно, не образуя очагов повышенного горного давления, подготовительные выработки на переходных участках закреплены податливым креплением, контроль окончания посадки кровли производится визуально при соприкосновении кровли с почвой выработанного пласта.An aimless method of producing coal seams, including moving the block of stope along the strike of the seam, as in a continuous development system, differs in that guard pillars are not left, the stope is collected in a block and located on a straight line, the rock is not transported from the excavation of the preparatory workings to the surface , and is placed in the space developed by the lavas, the roof is planted without hovering on pillars, evenly, without forming foci of increased mountain pressure, preparatory workings on p The transition areas are secured with a flexible mount, the control of the end of the roof landing is done visually when the roof comes into contact with the soil of the worked out formation.
