Abstract In this study, dust surveys were conducted at six underground mines in the United States to determine if deep-cut mining practices expose face workers to higher levels of respirable dust by comparing levels during the first 20ft of advance (regular-cut depth), during the deep cut to levels and during the final 10 to 20ft of advance (deep-cut depth). In general, all of the selected mines exercised good dust control practices by maintaining water sprays, scrubber airflows, proper curtain setback distances and providing sufficient airflow to the active faces. All of the operations surveyed for this study were able to successfully implement deep-cutting methods without significantly increasing the dust exposures of face workers during the cutting and bolting cycles. Implications of these and other findings are discussed.
