Coal mines are committed to decreasing their noise footprint within the local environment. One such coal mine initiated an important project to decrease the overall noise impact of their colliery.
Hushpak designed, manufactured and installed a noise curtain for the Rock Box. The curtain consisted of a series of steel and polymer impact blocks, which deaden the noise of coal impact. The arms supporting the impact blocks were designed to swing back, further dissipating the energy created upon impact. This solution yielded substantial levels of noise attenuation. Following the success of the first curtain installation, a second unit was designed, manufactured and installed in the Coal Bin.
