No flameproof mechanised system for cleaning under and around moving conveyors was found to exist anywhere. Of more than 200 mini machinery manufacturers identified worldwide, few build for mining, and only one or two products were near ready for surface use. Manufacturer interest in mining applications has since risen, but the industry has not settled on which technology to back.
More Effective Use of Disposable Dust masks
Underground field trials, laboratory seal tests and operator questionnaires at two collieries, covering mask selection, fit, issue records and service time. For ventilation and occupational hygiene staff.

Dust masks worn by load haul dump operators passed 200 mg of filter loading in an average of 1.7 hours, and continuous miner, shuttle car and roofbolt operators reached the same point within two to five hours. Every mask failed laboratory fit testing. An eight hour service life is too long.
