Abstract

The invention discloses a dust falling and grading drilling device facilitating position adjustment in a mine tunnel. The dust falling and grading drilling device comprises a multi-angle bending device capable of being lifted in a labor-saving mode, a splicing type hole washing and dust falling device, a multi-stage extending drilling device and a drilling equipment shell. The invention belongs to the field of mine tunnel drilling equipment, and particularly relates to a dust fall grading drilling device convenient for position adjustment in a mine tunnel. According to the invention, the air impinging stream is combined with the versatility of equipment, the space range of dust splashing is limited in advance, and the settling velocity of dust in a narrow mine tunnel is accelerated; in order to facilitate movement of the moving device in the mine tunnel with multiple gaps and prevent the moving device from being clamped in the gaps, the crawling equipment can quickly move on the inner wall of the mine tunnel by combining an asymmetric principle with a conical structure; in order to carry out deep drilling in a narrow space, the traditional operation mode of linear drilling of a single drill bit is changed, and two groups of nested drill bits are used for drilling, so that a multi-stage drilling function in a mine tunnel is realized.

Description

technical field

[0001] The invention belongs to the technical field of mine tunnel drilling equipment, in particular to a dust-suppressing graded drilling device that is convenient for position adjustment in a mine tunnel. Background technique

[0002] Underground mining refers to the process of extracting ore from the ore blocks of underground deposits, which is realized through four steps of mine development, mining of ore blocks, cutting and mining. The underground mining system mainly includes production management, rock drilling, blasting, ore extraction, ore sliding system, underground crushing, skip lifting and hoisting shaft system.

[0003] During the mining of underground mineral deposits, due to the narrow space of the underground mine, when the construction personnel need to drill holes on the side wall of the mine, the drilling equipment will be too long to carry out the drilling work in the narrow space, resulting in the The depth of the drilled hole is relati...
