Compiled by way of the U.S. Dept of healthiness and Human prone, CDC/NIOSH place of work of Mine defense and future health learn, this 2010 instruction manual used to be constructed to spot to be had engineering controls that may aid the decrease employee publicity to respirable coal and silica dirt. The controls mentioned during this instruction manual diversity from long-utilized controls that experience constructed into criteria to more recent controls which are nonetheless being optimized. The reason used to be to spot the simplest practices which are on hand to regulate respirable dirt degrees in underground and floor coal mining operations. This guide offers common details at the regulate applied sciences in addition to broad references.

This method of cutting leaves the rock in place until it can be cut out to a free, unconfined space, which creates less respirable dust (especially silica dust) [Jayaraman et al. 1988]. Figure 4-11 shows the modified cutting cycle. —Modified cutting cycle can lower dust generation. 53 FACE VENTILATION The velocity and quantity of face ventilating air are important factors for controlling respirable dust exposure of the continuous miner operator. A good ventilation plan consists of sufficient mean entry air velocity to confine dust near the face and/or direct it toward the return entry with high enough quantity for diluting generated respirable dust.
