Изобретение относитс к горной промьшшенности и предназначено дл управлени кровлей при разработке пологих угольных пластов.The invention relates to the mining industry and is intended to control the roof in the development of flat coal seams.
Цель изобретени - предотвращение деформации пласта и обрушени пород путем формировани искусственных опережаницих целиков из упрочненного угл ,The purpose of the invention is to prevent formation deformation and collapse of rocks by forming artificial advanced pillars from reinforced coal,
Способ осуществл етс следующим образом.The method is carried out as follows.
Из верхней или нижней выработки лавы впереди очистного забо на рассто нии , равном шагу естественного обрущени основной кровли параллель но линии очистного забо в непосредРедактор С.ПатрушеваFrom the top or bottom of the lava in front of the clearing slab at a distance equal to the step of natural collapse of the main roof parallel to the line of the clearing slab into the editor S. Patrusheva

ственную кровлю и пласт бур т скважины , по которым в кровлю и пласт нагнетают скрепл ющий раствор, начина с нижней скважины.The internal roof and the formation of the drill hole, through which the bonding solution is injected into the roof and the formation, starting from the bottom well.
5 Нагнетанием раствора создают опор- HFsie целики, размеры которых завис т от времени нагнетани и фильтрационных свойств пород и угл .5 By injecting the solution, pillars of HFsie are created, the dimensions of which depend on the injection time and filtration properties of the rocks and coal.
По мере подвигани забо опорный 10 целик, попада в зону опорного давле- ,ни , воспринимает на себ возрастающие от его действи напр жени , тем самым предотвращает обрушение непосредственной кровли и забо и 13 обеспечивает безопасные услови ведени работ.As you move the supporting 10 pillars, into the zone of the reference pressure, it perceives the stresses increasing from its effect, thereby preventing the collapse of the direct roof and the bottom and 13 ensures safe working conditions.
