湿式作业

采用湿式作业，安装除尘器及自动挡板等方法对输煤系统粉尘进行治理，取得良好效果。

Using the methods of the wet working setting the dust catcher and the autobaffle to control dust of the transporting system and the best effect is given .

提示薄煤层小型矿只要能采取以湿式作业为主的综合防尘措施，就能预防和控制煤工尘肺的发生和发展。

It suggests that occurrence and progress of CWP can be prevented and con - trolled if comprehensive dusc-control measures focused on wetting production can be adopted in small-sised coal mines with thin-layer coal seam .

结果采用了湿式作业，设置了适用的局部通风除尘系统：设计了专门的条缝型吸尘罩，其侧上吸罩罩口风速为2.5m/s、风量为600m3/h；

Results On the basis of adopting wet process in the carving operations , local exhaust ventilation system for dust control was installed , which included : the special designed slot exhaust hoods with hood face velocity of 2.5 m / s and exhaust volume of 600 m 3 / h.
