Claims (1)

Способ управления кровлей при слоевой выемке мощного пологового пласта угля, включающий проведение слоевых выработок, расположенных друг над другом, применение механизированных комплексов в лавах слоев, отрабатываемых в восходящем порядке с полной закладкой выработанного пространства, и дополнительное удержание вышележащих пород подкровельными сетками, анкерами и стойками выработанного пространства, отличающийся тем, что при отделении угля в нижних и средних слоях бурят в кровле вдоль лавы разгрузочные шпуры, высота которых составляет не более мощности вынимаемого слоя, расстояние по падению между шпурами не более ширины секций механизированного комплекса, расстояние между рядами шпуров по простиранию не более половины шага опускания непосредственной кровли, а угол наклона шпура в сторону массива принят равным 90o между линией шпура и линией, формирующей предполагаемый свод опускания вышележащих пород.A method of controlling the roof during layer excavation of a powerful coal bed, including conducting mine workings located one above the other, using mechanized complexes in the lavas of the layers worked out in ascending order with full laying of the worked out space, and additional holding of overlying rocks with roofing nets, anchors and racks of the worked out spaces, characterized in that when separating coal in the lower and middle layers, drilling holes are drilled in the roof along the lava, the height of which was it is no more than the thickness of the layer to be removed, the distance between the holes between the holes is not more than the width of the sections of the mechanized complex, the distance between the rows of holes along the strike is no more than half the step of lowering the direct roof, and the angle of inclination of the hole in the direction of the array is taken equal to 90 o between the line of the hole and the line, forming the proposed arch of lowering of overlying rocks.
