摘要
为了防治综采工作面的粉尘危害,采取了煤层注水、喷雾洒水、净化水幕等措施及隔绝瓦斯和煤尘爆炸的措施,对防尘管路管径、防尘注水量等进行了验算。采取综合防尘措施后,工作面呼吸尘的含量平均下降了77.2%,全尘含量平均下降了84.4%。
To control the dust hazard at fully-mechanized working face,the author presents the measures of water injection into coal seam,spray sprinkling,water curtain purification and isolating gas and coal dust explosion together with the checking computation of dust prevention pipe diameter and water injection rate,which have reduced the average respirable dust content by77.2%,the dust content by 84.4% at working face.
