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. ...
