Noise Test Report: Handheld Pneumatic Rotary Drill

Details:

Personal Authors:

Stein, Robert R. ; Aljoe, W. W. ;

Description:

Using an automated drill test fooure, the U.S. Bureau of Mines measured the sound power levels produced by a small, pneumatic, rotary roof drill. A series of tests was conducted to determine (1) the relative effectiveness of several drill muffling schemes and (2) the relationship between drill sound power and pneumatic power supplied to the drill. The influence of rotation rate (i.e., airflow) and feed thrust on the penetration rate of the drill was also noted.
