Abstract
Комбинированная засыпная забойка, включающая подвесной конус, выполненный из органического материала, например, из резины или пластической массы, соединенный с канатной тягой, и полифракционную засыпную часть с преобладанием щебня фракции 10-20 мм в первых порциях, отличающаяся тем, что подвесной конус выполнен с биконической проточкой в средней части. Combined backfill, including a hanging cone made of organic material, for example, rubber or plastic, connected to a cable traction, and a multifractional filling part with a predominance of crushed stone fraction of 10-20 mm in the first portions, characterized in that the hanging cone is made with biconical groove in the middle part.
