“…Summary of respirable dust measurements made in British coal mines during the late 1950s and early 1960s, carried out during the first two surveys of the Pneumoconiosis Field Research (PFR): conversion of respirable particle count concentrations (particles with diameter between 1µm and 5µm) from standard thermal precipitator samples to equivalent mass concentrations (fromRogan et al, 1967) …”

“…The latter included X-radiography, anthropometric measurements, lung function testing and respiratory symptoms questionnaires (Rogan et al, 1967). The British coal mining industry was prominent in many important developments in the period following the Second World War, including the evolution of sampling concepts and instruments and their application in the field.…”

“…As described earlier in this chapter, Rogan et al (1967) obtained particle size distributions from the counting and sizing of particles collected from coal mine atmospheres onto the slides of thermal precipitators and used the information obtained to link the thermal precipitator results with the gravimetric results obtained using later generations of respirable aerosol sampler.

“…Furthermore, by repeating the studies at intervals, e.g., every five years, as in the National Coal Board's Pneumoconiosis Field Research Study (Rogan, Rae, and Walton, 1967), the change in the RV/TLC over a five-year period in different groups can be studied. Were the RV to increase more in certain groups, an increased incidence of airways obstruction might be inferred in these subjects.…”

The results obtained from two radiological methods of determining total lung capacity (TLC) (Kovach's parabo-oid and Barnhard's ellipsoid) were compared with those obtained with the body plethysmograph. Determinations of TLC were made in four groups of subjects: group 1 consisted of 26 miners most of whom had simple pneumoconiosis; group 2 consisted of 12 normal subjects; group 3 consisted of eight subjects who had a variety of chest disease, but with no demonstrable parenchymal or pleural opacification; and group 4 consisted of 19 subjects with misce!laneous diseases, all showing demonstrable infiltration or opacification.The values obtained by the method of Kovach and his colleagues often differed markedly from the plethysmographic determinations, and it became apparent that this method was not sufficiently accurate. On the other hand, the technique of Barnhard and his colleagues gave results that were essentially similar to, and as far as we can say interchangeable with, those obtained by the body plethysmograph in groups 1, 2, and 3. In subjects with marked pulmonary opacification or infiltration, the disparity between Barnhard's method and the plethysmograph tended to be more sizeable. It was concluded that Barnhard's method for determining total lung capacity is accurate and could be applied to epidemiological surveys.

Coal is an organic, combustible, rock‐like natural substance that occurs in various forms from hard and brittle anthracite to soft and friable lignite. Coal mine dust often contains silica and other minerals found within the coal seam or in the adjacent strata. In the United States and other countries, coal miners are at risk of developing chronic lung diseases caused by cumulative exposure to respirable coal mine dust. These diseases can lead to significant lung function impairment, disability, and premature death. Collectively known as “black lung,” they include a spectrum of interstitial lung diseases including coal workers' pneumoconiosis (CWP), mixed dust pneumoconiosis, and dust‐related diffuse fibrosis as well as chronic airway diseases including emphysema and chronic bronchitis. Since the late 1990s, the prevalence of CWP and its most severe form, progressive massive fibrosis, have increased in the United States, most notably in central Appalachia. Factors contributing to this resurgence might include thin‐seam coal mining and/or cutting rock to access coal seams, which likely exposes miners to respirable coal mine dust with a higher content of other hazardous dusts including silica and silicates. Many countries have occupational exposure limits for coal mine dust typically based on assessment of the mass of dust collected during a work shift.
