Progress of Windproof Net and Its Application and Countermeasure to Large-scaled Coal Ports
Zhao Hai-zhen · The Research of Environmental Sciences · 2007
Windproof net is an effectual measure to control the form and diffusion of coal dust,and the effect is related to its structure and setting.Although it is well known that windproof net is very useful to control the form and diffusion of coal dust,the windproof net has not been widely applied to large-scaled coal ports.There are two reasons: ① the scale of coal storage yard is large in China,but the effectual range of windproof net is limited with a distance about 20 times of its height in leeward direction,which limits wide application of the measure;② the cost of windproof net is relatively high,and the cost is usually more than one million yuan every one-hundred meter.In order to popularize the application of windproof net in large-scaled coal ports in China,it is necessary to strengthen the research of appropriate scale of coal storage yard, effectual range and new material of windproof net,etc.,and to select some large-scaled coal ports in the North to apply windproof net.
