Determination of rational technological schemes for the completion of open-pits taking into account land reclamation

Abstract

The analysis of objects of landscape disturbances under opencast mining is carried out. The arrangements for reclamation of residual mines and earth’s surface relief formation at the opencasts of the Pokrovskyi mining and processing enterprise are determined. The basic approaches for final extraction of opencasts in order to mining method are investigated. Reclamation processes during final open-pit mining are justified, taking into account the development of mineral reserves at the ends of the open-pit.

Rationale of effective technological scheme for granite quarry mining

“…The use of two adjacent rock chutes ensures continuous operation of the equipment, that is, when one is unloaded, the mined mass is removed from the platform of the second, and then vice versa. However, provided that the work is non-permanent and a temporary storage facility is arranged on the lower platform, a single rock chute is enough [16].…”

Establishing the influence of the excavator standard sizes on the kaolin pit mining system parameters

“…The main parameters of the mining system of the Rozivskyi pit for the performance of kaolin mineral deposit extraction according to the current project are given in the Table 1. Excavation work [22] in the pit begins with the removal of the soil-vegetation layer with a Caterpillar D6R-II or Komatsu D65 bulldozer, the soil-vegetation layer is pushed into the side with the same bulldozer, and the Volvo EC 480D excavator is loaded into Volvo A45 trucks and taken to the temporary storage of the soil-vegetation layer on the internal dumps surface [23].…”
