INTRA-BOARD TRANSFER POINT FOR DEEP PITS OF AREAL FORM Russian patent published in 2016 - IPC E21C41/26 

FIELD: mining.

SUBSTANCE: invention relates to open mining of mineral resources. This task is solved by arrangement of reloading stations on two-lane internal benches, which width is divided into two equal parts by combined wall with height of 6-8 m, consisting of tubes installed in specially drilled wells, and steel sheets welded to pipes. Space between wall and ledge is filled with slant of exploded rock mass, forming from it stock with one lane steeply inclined cross-over from side of assembly transport entrance and unloading site on opposite side. In adjacent to warehouse slope of ledge at level of upper store site in out of outline array tunnel is passed with free length and cross-section that allow accommodate one dump truck as means for creation of normal conditions for manoeuvring and high-efficiency operation of transport, loading and auxiliary equipment in operating conditions of reloading point with limited dimensions.

EFFECT: technical result is reduction of volumes of additional offset of open pit edges by reducing size of reloading stations, making overload of rock collecting small capacity vehicles into mainline high-capacity vehicles.
