Open pit mine loading method achieving cost reducing and efficiency improving by changing inherent loading working procedure

Abstract

The invention discloses an open pit mine loading method achieving cost reducing and efficiency improving by changing an inherent loading working procedure. The open pit mine loading method comprises the following steps that (1) blast holes are punched in an operation platform according to a production plan; (2) gunpowder is installed in the blast holes for blasting; (3) a gunlock directly conducts surface layer boulder breaking secondary blasting on a blasting pile; (4) blasting pile clearing and gathering are conducted to form a gathered pile; (5) surface layer shovel mucking operation is conducted; (6) the gunlock directly conducts boulder breaking secondary blasting on a novel surface layer; (7) surface layer shovel mucking operation is conducted; and (8) the two steps (6 and 7) are repeated till the blasting pile truck loading and conveying are completed. Owing to the fact that the inherent loading working procedure of a mine is changed, the process that shovel mucking is conducted after boulders are taken out for centralized stockpiling and centralized breaking secondary blasting is not conducted any longer, and the gunlock is directly utilized to conduct surface layer boulder breaking secondary blasting in a batched mode on the blasting pile, so that the loading work procedure process is simple, truck loading efficiency is high, truck loading and breaking secondary blasting operation is little in interference, safety is high, cost is low, and the open pit mine loading method achieving cost reducing and efficiency improving by changing the inherent loading working procedure is adaptable to the current rapidly-developed mining mine technology and the energy conservation and emission reduction policy proposed by China.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to an open-pit mining and loading method for reducing costs and increasing efficiency by changing the inherent mining and loading procedures. Background technique [0002] Minerals are an important basic material for national production and construction. With the rapid development of economy, the consumption of mineral resources is increasing rapidly, and the mining of mineral resources is becoming more and more common. The mining and shoveling of ore is an extremely important step in the mining process, which directly determines the efficiency, cost and safety of mining. [0003] The Chinese invention patent with the publication number CN201210234382.5 discloses a method for ore recovery in closed-pit open-pit mines, which was invented to shorten the recovery period and improve production efficiency. It includes: determining the corresponding mining method according to the occurren...

AI Technical Summary

Problems solved by technology

The process flow is cumbersome, the loading efficiency is low, and there is no large-scale processing that can be solved first.

As a result, it takes a lot of time to remove large blocks during loading, and the loading and unloading process interferes greatly, with low equipment efficiency, high energy consumption, high cost, and low safety. This is in line with the current rapid development of mining technology and the energy-saving and emission-reduction policies advocated by the state. Violation requires process optimization
