A swashing dust catcher is used in the powder dust pollution in a-616 m underground crushing station of a copper mine in Anhui Province and the powder dust concentration at the working positions is reduced from 50 mg/m~3～60 mg/m~3 in the past to about 2 mg/m~3 at present.This not only makes the powder dust concentration basically reach the national sanitation standard,but also purifies the ...

2007-2-1 The dominant ventilation inflow to the crushing facility is the updraft airflow flowing from the lower chamber opening (G) at the base of the gyratory crusher. This updraft airflow produces a significant deflection of the other ventilation airflows entering the excavated chamber through portals A–C in the vicinity of the crusher feed bin.

With long-term mining and new orebodies proved to be in the deep, the dust concentration of each mine underground operation site increased sharply, which is a serious threat to safety and health of workers in workspace. In this paper, a high pressure spray technology was put forward for dedusting on a mine underground middle crushing station[, and achieved the desired dedusting effect.

Underground mining operations are, in many cases, provided with a substantial surge capacity between the mine and the primary crushing plant. Furthermore, in medium and large operations of this character, the primary crusher is almost invariably large enough (to meet the required output) so that the mined ore causes little or no trouble due to ...

2021-5-3 The sources Sources and characteristics of particulate matter (PM) were determined in a modern underground chrome mine in Finland. Measurements were conducted at five locations in the mine: the maintenance area, blasting area, ore pit dumping area, crushing station and conveyor belt. The measurement set-up consisted of a Soot Particle Aerosol Mass Spectrometer (SP-AMS) for the

To give some context, an example metal mine might spend $5.00/t of ore on electricity; an equivalent amount on grinding media in the SAG circuit alone; but only $0.30/t

Suppressing and removing mine dust from the working face is an important task for underground mines worldwide. In this paper, a numerical study was carried out to investigate the influence of ventilation arrangement on the mechanism of dust distribution. The Woxi Pithead of Hunan Chenzhou Mining Co., Ltd, China, was used as a case study, which adopted a widely used far-pressing-near-absorption ...
