Problems solved by technology

[0003] Since the early 1980s, the mining order in my country has been relatively chaotic. A large number of civilian mining has resulted in many goafs in the natural mine body, and due to the lack of advanced mining equipment and scientific mining methods in the natural mine body, the The shape and structure of the goaf are unscientific, and its distribution is irregular, resulting in poor stability of the goaf, and personnel cannot directly enter the goaf to work, which has caused great difficulties for the safe and efficient mining of the ore body, and caused mining problems. The problem of high loss rate and dilution rate of ore in the process

Embodiment 1

[0024] The mining technology of a kind of copper ore provided by the present embodiment comprises the following steps:

[0025] (1) Mining area setting: the outside of the mining area is equipped with ventilation facilities that deliver fresh air to the mining area; gas detection and alarm equipment is installed in the mining area;

[0026] (2) Prospecting: Arrange exploration lines with a certain distance in the direction perpendicular to the length of the main body of the ore body on the predetermined elevation, and excavate the prospecting roadway along the exploration lines until the entire ore body is broken down;

[0027] (3) Mining: Mining is carried out by means of large-section excavation. At the same time as mining, the four walls of the vacant mining area that has been mined are constructed with a reinforced concrete structure into an annular body with four sides, up, down, left, and right. Every time a section is mined forward, a section of the ring is constructed. ...

Abstract

Relating to the technical field of mineral exploration, the invention provides a copper ore mining process. The process includes the steps of: (1) mining area setting, (2) prospecting, (3) mining, (4)stoping, and (5) desliming. The mining process provided by the invention has high control degree on the ore body, can effectively improve the copper ore recovery during mining and reduce the loss rate and dilution rate of copper ore, improves the utilization rate of mineral resources, provides resource guarantee for sustainable development of mines, and has good use value and application prospects.

Description

【Technical field】 [0001] The invention relates to the technical field of mineral mining, in particular to a copper ore mining process. 【Background technique】 [0002] Copper is one of the earliest copper alloys discovered by humans. It is soft, ductile, and has good thermal and electrical conductivity. It can be processed into tools and daily necessities with a little tapping. The development of human society depends on materials, and mineral resources are one of these important material bases. At present, more than 95% of energy, more than 80% of industrial raw materials and more than 70% of agricultural production materials come from mineral resources. Most of the mineral resources come from mines, and open-pit mining construction stone mines, as a part of various mines in my country, can account for about 60% of the total mines in terms of the number of mines. The overall development of comprehensive utilization of resources plays a pivotal role. In the field of construc...
