Claims (1)

Способ отработки рудных месторождений, включающий проведение подготовительных, нарезных работ, обуривание блоков, отбойку и выпуск руды через выпускные выработки, в котором нарезные работы на нижележащем горизонте проводятся вне зоны опорного давления с отставанием по отношению к очистным работам на вышележащем горизонте, отличающийся тем, что нарезные и подготовительные работы на нижележащем горизонте проводятся с отставанием от очистных работ на вышележащем горизонте на величину, определяемую из выражения
Figure 00000001

где Н - глубина разработки, м;
α - угол залегания рудных тел, град;
L - расстояние до фронта очистных работ, м,
при этом очистные работы в очередном блоке отрабатываемого горизонта проводятся с отставанием от его подготовительных и порезных работ на 3-4 блока.A method of mining ore deposits, including preparatory, rifling, drilling blocks, breaking and releasing ore through exhaust openings, in which rifling on the underlying horizon is carried out outside the reference pressure zone with a lag with respect to treatment on the overlying horizon, characterized in that threaded and preparatory work on the underlying horizon is carried out with a lag behind the treatment work on the overlying horizon by an amount determined from the expression
Figure 00000001

where N is the depth of development, m;
α is the angle of ore bodies, degrees;
L is the distance to the front of the treatment works, m,
at the same time, treatment works in the next block of the worked out horizon are carried out with a delay of 3-4 blocks from its preparatory and cutting work.
