Abstract
PURPOSE: To suppress heat generation by oxidation, etc. and to prevent of spontaneous combustion of coal, by spraying an aqueous emulsion consisting essentially of a water-insoluble polymer, surface active agent, and water retentive agent on heaped coal so that a film having improved wetting properties, slightly causing cracks, is formed on the coal.
CONSTITUTION: (A) 50W98wt% Water-insoluble polymer, e.g., vinyl acetate type polymer, etc. is blended with (B) 1W30wt% surface active agnet and (C) 1W 30wt% water retentive agent, e.g., lower alcohol, glycerol, etc. to give an aqueous emulsion consisting of 0.05W10wt% (preferably 0.5W5wt%) three components. A compound shown by the formula I (R1 is 8W18C alkyl, etc.; p is 3W100), and a compound shown by the formula II (R2 is 8W12C alkyl, etc.; q is 3W100) are especially preferable as the component B. In spraying, the heap of the coal and the spray of the emulsion are repeated alternately during piling the coal, so that the emulsion is effectively sprayed in layer state.
