Abstract: Combining with a practical windproof and dust suppressing net project installed in coal yard of Huaneng Weihai Power Plant project phase III, the performances of windproof and dust suppressing nets made of different materials were compared. The selection method of material for wind proof and dust suppressing net and the matters needing attention in construction were expounded. In Huaneng Weihai Power Plant project phase III, after the windproof and dust suppressing net was put into use, the coal dust loss can be decrease by 700 thousands RMB yuans in an year, favorable economical benefit and social effect were obtained.

Key words: wind-proof and dust suppressing net, macromolecule composite material, metal material, coal dust loss
