A swashing dust catcher is used in the powder dust pollution in a-616 m underground crushing station of a copper mine in Anhui Province and the powder dust concentration at the working positions is reduced from 50 mg/m~3～60 mg/m~3 in the past to about 2 mg/m~3 at present.

The installation of fine dust on-line monitoring equipment in the BF gas dust-removing system and the entrance pipes of TRT unit can efficiently control the efficacy of dust bags and realize the on-line detecting of gas dust content in TRT unit entrance pipes,thus ensuring the running conditions of TRT unit and its long-term, high-efficient and safe running.

The initiation of the cracks was caused by stress corrosion resulting from the co-effect of the corrosive gas dust and the axial tensile stress.

Gauss mode's using in measure and calculation of coal-flat and coal dust's exhanst stress;

Coal dust could drop soil pH and increase EC and organic matter insoil to some extent,especially in the top layer of soil.

This paper analyzes the causes of coal dust pollution and its harm in coal feeding system of fuel workshop which exists in hot electricity department in Tianjin petrochemical company, and offers compre- hensive treatment plan integrated with the factual conditions.
