Silicosis is one of the major occupational lung diseases among stone miners; currently, it is a major concern in India given its 12-30% prevalence. The objective of this study was to determine the exposure profile of respirable dust and crystalline silica concentrations from sandstone, masonry stone, and granite stone mines in India.

The problem with that approach is that most coal mines currently operating in Appalachia require miners to cut through large amounts of sandstone, the source of silica dust. As a result, it is entirely possible for a coal mine to comply with even a lowered total respirable dust level, but still contain unsafe levels of silica.

What is Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
