Abstract

1. Способ отработки целиков, включающий проведение полевых выработок, предварительную отрезку целиков от кровли, обрушение пород кровли в выработанное пространство камер, разбуривание и взрывание целиков, выпуск отбитой руды под обрушенными породами через полевые выработки, отличающийся тем, что, с целью повышения показателей полноты и качества извлечения руды и повышения безопасности работ по выемке целиков, первоначально на почву камер укладывают перекрытие, затем из выработанного пространства камер разбуривают и взрывают верхнюю часть целиков, а после обрушения пород кровли проходят полевые выработки.2. Способ по пп.1 и 2, отличающийся тем, что, с целью обеспечения возможности выемки находящихся в предельном состоянии целиков, предварительное обрушение пород кровли в выработанное пространство камер осуществляют взрыванием группы наиболее устойчивых целиков.1. The method of working out the pillars, including carrying out field workings, preliminary cutting of the pillars from the roof, collapsing roof rocks into the worked out chamber space, drilling and blasting the pillars, releasing broken ore under the collapsed rocks through field workings, and the quality of ore extraction and increase of safety of work on the excavation of the pillars, initially overlap the chambers on the soil of the chambers, then drill out of the chambers and blow up the upper st pillar, but after the collapse of the roof rocks are vyrabotki.2 field. The method according to claims 1 and 2, characterized in that, in order to ensure the possibility of excavation of the pillars that are in a state of limitation, the preliminary collapse of the roof rocks into the developed space of the chambers is carried out by blasting a group of the most stable pillars.
