Description

technical field [0001] The invention relates to the field of dust removal for mining equipment. Background technique [0002] The roadheader in the excavation working face produces a large amount of dust during the working process, which is one of the main sources of dust in the excavation process and the working face. The problem of dust reduction is one of the technical problems faced by the coal industry worldwide. The general dust concentration reaches 700- 800mg / m 3 , it can exceed 1000mg / m when encountering extra-hard coal areas 3 . [0003] The existing dust control technology in the tunneling process of the roadheader on the working face mainly adopts the method of installing nozzles on the roadheader for spraying and dust reduction. Since the water source used in this method is low-pressure natural water, the atomization effect is poor, and the dust concentration is as high as 500mg / m 3 Above, can not effectively catch the dust that produces in the excavation pr...

AI Technical Summary

Problems solved by technology

Since the water source used in this method is low-pressure natural water, the atomization effect is poor, and the dust concentration is as high as 500mg / m 3 Above, the dust generated during the excavation process cannot be effectively captured

In addition, the extraction type wet fan dust removal, due to the large size of the equipment and the limited installation location, cannot effectively treat the dust near the dust production point. The driver and some staff are still in a high dust environment, and the dust removal efficiency is also affected by the roadheader process. Influence, unable to adapt to high-efficiency excavation

[0004] In short, workers working under such conditions not only reduce the production efficiency of workers and increase the probability of various industrial accidents, but also have the possibility of coal dust explosions, threatening the safety of mine production.
