This paper expounds the working principle of the intelligent dust-tracking and dust-falling system on the coal cutter, and emphatically introduces the improving and perfecting procedures of this system, and sums up and analyzes the social benefit and economic benefit obtained after the application of this system.

Taking the coal storage yard of Gushuyuan Coal Mine,Jincheng Coal Mining Group,as the example,this paper introduces the present situation of dust thickness exceeding the standard in storage at present,and analyzes the dust suppression effect with the application of new high-pressure spraying system for dust suppression.

Discussing the energy conservation in the dedusting system;

Application analysis of various kinds of adjusting valves for dedusting system;

Comprehensive improvement on dedusting system for 40 t EAF at Guanggang;

Effect of cooling on-machine on dust removal system;

For flax textile enterprises,correctly selecting of dust extracting equipment and rational division of dust removal system is very important in taking measures of safety,fire prevention and explosion protection in the production.

Combining with the existing designs and constructions of dust removal system in coal terminals,this paper gives a comprehensive comparison to the efficiency and adaptability of dust catchers,presents suitable types of dust catchers,and conducts a simple calculation for dust removal system.
