Polymers for combatting sudden outbursts in coal mines

Journal Article:

Abstract

Describes investigations in coal mines in the Donetsk basin (hazardous because of the high methane presence, the risk of outbursts of coal and gas, underground fires and the high dust levels) with the aim of studying the toxic emissions of formaldehyde and methanol produced when a urea formaldehyde resin binder is applied to the coal seam. The measurements taken led to the following recommendations: the amount of free formaldehyde in the binder should be limited to 0.5%; the use of concentrated (50%) solutions should be limited to 10 l per ton of coal in areas where there are geologic faults; underground workings need ventilation of at least 200 m/sup 3//min; the binder should be introduced to the borehole separately from the water and hardener; individual protection measures and wet dusting should be used during coal extraction; a period of not less than 4 months should elapse between application of the resin and commencement of coal extraction; there should be at least 80 m between the point where the binder is applied and the coal face.
