The practice application situation of compound dry coal preparation is introduced Sulfur content of NO 10 coal seam reach 4 2% Sulfur content can be reduced through dry coal preparation At the same time, a better economic benefit can be gained.

Study on a new alcohol-soluble adhesive for dry lamination;

A two - component polyurethane adhesive with high solid content, low viscosity for dry lamination was prepared.

From investigating the properties and raw materials of AD adhesive for dry lamination and synthesis technology of acrylate copolymer, we can draw the conclusion that along with the cost of AD adhesive reduced by 20—30%, its properties can reach or even be superior to those of common polyurethane adhesives for dry lami-nation.
