摘要
通过分析凉水井煤矿综掘工作面产生粉尘的实际情况,改进了长压短抽通风除尘的方法,在原有局部通风系统的基础上增加了集尘罩、负压风筒、除尘器、附壁风筒,形成了一整套适合该矿掘进工作面生产条件的通风除尘系统,经实测,采用长压短抽的方法后掘进工作面生产时总粉尘浓度降尘率达92. 5%以上,降尘效果明显。
By analyzing the causes of dust in fully mechanized excavation face in Liangshuijing coal mine,the dust removal method of long pressing and short pumping ventilation was improved.On the basis of the original local ventilation system,dust collecting cover,negative pressure air cylinder,dust collector and wall-attached air cylinder were added,and a set of ventilation and dust removal system suitable for the production conditions of the tunneling face was formed.The actual measurement shows that the dust reduction rate of the total dust concentration in the heading face is over 92.5%,and the dust reduction effect is obvious.
