Description

Technical Field

[0001] The invention relates to the technical field of underground mining, in particular to a deep hole ranking and marking device for underground mining. Background Art

[0002] Underground mining is referred to as pit mining. It is a general term for mining in underground tunnels. It is generally suitable for ore deposits with deep ore bodies that are not suitable for open-pit mining economically and technically. With the continuous development of industry, underground mining technology and ore mining activities are gradually evolving in the direction of "mechanization and precision". Especially for ore bodies with complex structures, developed faults and joints, and constrained by unstable surrounding rocks, it is necessary to select a mining process that can achieve low risk, low loss, high resource recovery rate, and low safety threats.

[0003] Based on the above, the inventors have found that the existing underground mining deep hole ranking and marking device mainly has the following shortcomings. For example, the existing underground mining deep holes need to be marked after ranking, and the marking needs to be done by spraying paint, and the paint spraying is located in a narrow position in the deep hole of the mine, which makes the work difficult, resulting in the accuracy of the ranking marking in the mine, causing deviations in the specific position of the blasting, affecting the effect of the blasting. Summary of the invention

[0004] In view of the above problems, the present invention provides an underground mining deep hole ranking and marking device.

[0006] Furthermore, the support structure includes a support plate, support feet, a guide tube, and a deceleration structure. A support foot is provided at the bottom of the support plate. There are four support feet, and the bottom of the support foot is conical.
