架间立体喷雾在余吾煤矿综采工作面中的应用

Application of Three-dimensional Spray Between Supports on Fully-mechanized Working Face of Yuwu Coal Mine

余吾煤矿通过合理布置液压支架喷雾系统,把架间产生的粉尘有效控制在人行道和煤壁间较小的区域内,使含尘气流紧靠煤壁运动,提高了降尘效果。

By optimizing the inter support spraying device of fully-mechanized working face in Yuwu Coal Mine, the dust produced between the supports can be effectively controlled in the smaller area between the sidewalk and the coal wall, so that the dust laden airflow can move close to the coal wall to improve the dust suppression effect.
