Method for improving mining safety

Abstract

The invention relates to a method for improving mining safety. A mine drilling device is used in the method. The mine drilling device comprises a lifting seat, a soil removing unit and a drilling unit; the soil removing unit is arranged at the left end of the lifting seat; and the drilling unit is arranged at the lower end of the soil removing unit. According to the method, by means of the designed annular drilling head, vibration during drilling is reduced to a great extent, soil and stone in a drilling barrel are crushed and removed through a soil removing mechanism, vibration transmitted outwards is reduced through the drilling barrel, thus the vibration strength is doubly reduced during drilling, and the problems of rockfall, even mine collapse and the like caused by excessive vibration during drilling are solved; and by arranging the mechanism for removing the crushed soil and stones in the drilling barrel, the problem that floating soil in a hole needs to be manually removed after drilling is solved, and the labor intensity of workers is reduced.

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
