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

摘要: 对综放工作面的粉尘产生规律进行了分析,并对现在常用的防尘措施进行了总结,在此基础上提出了相应的防尘措施。现场使用效果进行实测后果表明,采用该防尘措施后采煤机司机下风侧1.5 m处降尘效率为81.25%,机尾下风侧10 m处降尘效率为85.33%。

Abstract: 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.
