Abstract
In the practice of development of mineral deposits there are many cases of application of combined development systems with extraction of chamber reserves and leaving temporary pillars. In this case, at deposits with relatively stable ores and rocks, the chambers are usually mined by highly efficient systems with subsequent filling of the goaf with dry backfill material – rock from development workings and open‑pit overburden. In the left inter‑chamber and inter‑level pillars often remains up to 50‑60% of the total reserves of the deposit, which are extracted by labor‑intensive and low‑performance systems (slice caving, with post support and backfill, etc.)...
