Laboratory results of a 3rd generation roof bolter canopy air curtain for respirable coal mine dust control被引量：6
《International Journal of Coal Science & Technology》2019年第1期15-26,共12页W.R.Reed G.J.Joy M.Shahan S.Klima G.Ross 
Testing was completed on an earlier roof bolter CAC that used slots to provide a perimeter airflow. NIOSH tested it due to its unique design that differed from canopies that provided uniform airflow. Based upon NIOSH ...

Laboratory results of foam application testing for longwall shield dust control in a simulated environment
《International Journal of Coal Science & Technology》2021年第2期217-227,共11页W.R.Reed M.R.Shahan Y.Zheng A.Mazzella 
There were 37 longwall faces operating in mines in the United States in 2019.The average panel width for these longwalls was approximately 368.5 m(1209 ft).This translates to a range of approximately 170-240 shields p...
