Specific embodiment
In such as Fig. 1, a kind of subterranean tunnel drillhole blasting dust degeneration system, apart from the boring work face 1 of subterranean tunnel 5
Certain distance is provided with mobile closed door 2, and mobile closed door 2 is provided with mobile chock dust remover 4, mobile chock dust remover 4
Blast pipe 43 be connected with air-blast device 3, the discharge pipe 44 of mobile chock dust remover 4 is located within mobile closed door 2.This example
In mobile closed door 2 within refer between mobile closed door 2 and boring work face 1 within space.
The first air exhauster 6 being additionally provided with outside tunnel located underground 5, the first air exhauster 6 is connected with the first airduct 7, and first
The air inlet of airduct 7 is located within mobile closed door 2.
The second air exhauster 6' being additionally provided with outside tunnel located underground 5, the second air exhauster 6' are connected with the second airduct 7', the
The air inlet of two airduct 7' is located at outside mobile closed door 2.
When using, mobile closed door 2 and mobile chock dust remover 4 are arranged on the emphasis area for needing to carry out dedusting work
Domain, that is, to the more strict position of air quality requirements, typically apart from the position of boring work face 120-30 rice, at this
The dust of generation is more.Its major function is the dust that degraded drillhole blasting is produced, and air-blast device 3 is extracted into into mobile chalk dust removing dress
The dust degraded in 4 is put, the air of cleaning is then discharged out.Start mobile chock dust remover 4 before explosion is ignited.10 minutes
Exclude comprising the new space formed after explosion, the typically dust in the distance of working face 30-50 rice.Workman can enter
