"Wet-head" tests on miners concluded.
Coal Min and Processing 1975 Apr; 12(4):78-80, 88
The Bureau of Mines sponsored underground research to determine whether continuous miners with "wet heads" (water through the cutters) reduced respirable dust compared with fixed sprays only. Tests were conducted on Joy, Jeffrey, Lee-Norse, and Wilcox continuous miners in operating mine production sections. Data are given that show coal production, airflow and waterflow, and dust levels at the high-risk operator position and in the returns. Two of the "wet-heads" reduced dust levels at the high-risk operator position by 56 and 44 percent, and three of them reduced dust levels in the returns by 47, 20, and 13 percent.
