A method of improving mining safety

Abstract

The invention relates to a method for improving the safety of mining, which uses a mine drilling device, the mine drilling device includes a lifting base, a soil removal unit and a drilling unit, and the left end of the lifting base is provided with a soil removal device. unit, the lower end of the soil removal unit is provided with a drilling unit; the invention greatly reduces the vibration during drilling through the designed ring-shaped drilling head, and then uses the soil removal mechanism to break and remove the soil and rocks in the drilling cylinder, and the drilling The hole tube reduces the vibration transmitted outwards, thereby double reducing the vibration intensity during drilling, and solves the problem that if the vibration is too large during drilling, it will cause rockfall or even mine cave collapse; The removal mechanism solves the problem that the floating soil in the hole needs to be removed manually after drilling, and reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to a method for improving the safety of mining. Background technique [0002] Mining mining technology refers to the mining technology of valuable natural mineral resources by manpower or machinery. According to the different burial depths of ore deposits and the requirements of technical and economical rationality, mining techniques can be divided into open-pit mining and underground mining. Open-pit mining is used for the parts close to the surface and shallow buried, and underground mining is used for the deep parts. [0003] For an ore body, whether to use open-pit mining or underground mining depends on the occurrence state of the ore body. If open-pit mining is used, the reasonable depth should be used. There is a problem of depth boundary here, and the determination of depth boundary mainly depends on economic benefits. Generally speaking, if the boundary stripping is l...

AI Technical Summary

Problems solved by technology

[0004] When the mine is mined, the mine is often blasted, and there are the following problems in the blasting process: one, need to manually drill the hole before the blasting, and the workers of the drilling have certain potential safety hazards in the drilling process. Excessive vibration will lead to problems such as rockfall and even mine collapse; 2. The existing equipment often cannot remove the floating soil in the hole when drilling, and even needs to manually remove the floating soil in the hole after drilling, which greatly increases Reduce the labor intensity of workers and reduce the work efficiency of workers
