Dust Producing Regularity and Dust Suppression Measures on Fully Mechanized Caving Face

The dust producing regularity on fully mechanized caving face was analyzed,the common dust suppression measures was summarized,corresponding dust suppression measures were raised on the basis of those analysis.The result of testing shows that the dust suppression efficiency on the 1.5 m downstream of coal cutter operator is 81.25% and the dust suppression efficiency on 10 m downstream of coal cutter is 85.33% by using this dust suppression measures.
