MSHA's final rule to lower miners' exposure to respirable coal mine dust is a historic step forward in the effort to end black lung disease. The rule reduces overall dust standards in coal mines, improves the dust sampling technology and methodology, and expands the medical surveillance program to improve early detection of the disease.

Measured and reported to the operator in mg/m3 (milligrams per cubic meter) of air in the environment at time of sampling. Initial standard established at 3.0 mg/m3 under the 1969 Act. Final standard under 1969 Act and continuing until July 31, 2016 is a maximum of 2.0 mg/m3. Maximum dust standard reduces to 1.5 mg/m3 on August 1, 2016.
Respirable crystalline silica – very small particles typically at least 100 times smaller than ordinary sand found on beaches or playgrounds – is generated by high-energy operations like cutting, sawing, grinding, drilling and crushing stone, rock, concrete, brick, block and mortar; or when using industrial sand.
or fatal. Silica dust is generated in most mining activities, including cutting, sanding, drilling, crushing, grinding, sawing, scraping, jackhammering, excavating, and hauling materials that contain silica, and is found in all mines -- underground and surface metal and nonmetal (MNM) and coal mines.

The transportation process of demolition materials in nearly all industries creates pesky dust. At concrete crushing facilities, dust is generated at multiple points. Front end loaders, hoppers, and conveyor discharge points all bring dust when operational. Front end loaders transfer the incoming demolition materials to the hopper.

Airborne coal dust is also explosive, given the right particle size, concentration, and ignition source. Bureau of Mines studies have shown that ignitable airborne coal dust concentrations start on the order of 50g/m3 (0.05 oz./ft3) [5,6]. The most explosive coal dust size in air is below 75 nm (—200 mesh) [5,6].
75.4% control efficiency for "process" material and a 86.7% control efficiency for "fines" material. These factors are substantially different from those used previously by the District. Trace metal concentrations in aggregate dust released from aggregate crushing operations can vary between sites.

Dust sampling is the process of using sensitive equipment to take samples in the mine atmosphere. The ultimate goal of operator sampling activities is the prevention of occupational diseases, like PNEUMOCONIOSIS. 2 types of pneumoconiosis we are most concerned with in the mining industry are Coal Worker's Pneumoconiosis (CWP or …
For metal and nonmetal mines where the operator has not timely abated hazards, MSHA will issue a 104(b) withdrawal order until the silica overexposure hazard has been abated. For coal mines, MSHA will encourage changes to dust control and ventilation plans to address known health hazards.
