Mining system and method of mines

Abstract

The invention discloses a mining method of mines. The mining method comprises an obtaining mining step of mineral aggregates and a transportation step of transporting the mineral aggregates. In the mining method, the mines are divided into a plurality of mining faces in the depth direction, and each mining face is divided into a plurality of mining sections in the length direction. Mining operation is carried out in the width direction of a first mining section, and then mining of the next mining section is carried out. When mining of the mining face on a first layer is completed, mining of a next mining face on the lower layer is carried out. The invention further provides a mining system of mines capable of completing the mining method. By means of the technical scheme, the mining method is a layer-and-layer mining method, continuous mining of the mines can be completed through the mining system, and stability of side slopes cannot be influenced.

Description

technical field [0001] The invention relates to the mining field of mines, in particular to a mining method of a mine and a mining system applying the mining method. Background technique [0002] At present, in the field of mining, taking open-pit mining as an example, the main technology used at this stage is the single bucket-auto semi-continuous mining process. The process of this mining process is: drilling - blasting - mining - transportation, The corresponding required equipment mainly includes single-bucket excavators responsible for mining, trucks responsible for transfer, and pitside semi-stationary crushers or mobile crushers responsible for crushing. The procedure of this mining process is as follows: a single-bucket excavator loads the mineral material after drilling and blasting onto a truck, and the truck transports the mineral material to the crushing station for crushing so that the particle size of the mineral material is ≤300mm, and finally The crushed ore...

AI Technical Summary

Problems solved by technology

[0003] The latter continuous mining method can basically overcome the low mining efficiency, high labor cost, and complex mining process in the former mining method. It needs to go through drilling, blasting and crushing links, and the mining cost is high. A lot of equipment, high cost of main equipment, high mining investment cost, etc.

However, for the bucket wheel-belt conveyor continuous mining process, there are also the following disadvantages and limitations

Because this kind of mining technology uses the bucket wheel excavator to directly mine the side and end faces of the steps of the mine, the slope after mining is unstable, and the mining surface is extremely uneven, and safety accidents such as collapse have occurred, resulting in potential safety hazards

In addition, because the bucket wheel excavator can only deal with open-pit mines with large stripping volume and soft minerality, it has high requirements on the lithology of the mine, thus greatly restricting the application range of this technology
