“…Coal dust, asbestos dust, benzene, and noise were the risk factors for psychological health problems of factory workers and miners, and the risks of psychological health problems increased 1.19 times, 1.58 times, 1.28 times, and 1.23 times compared with those who had no exposure, respectively. Occupational dust was an important health risk in modern society, and the adverse health impacts of coal mine particulate matter had been well known [ 33 , 34 ]. Changes in the body's functioning due to occupational dust exposure, such as developing respiratory symptoms and decreased pulmonary functions, could make workers feel more tired at work and thereby increase the possibility of work errors, leading to psychological burden.…”

This study is to evaluate the effects of different occupational hazards on job stress and mental health of factory workers and miners. A total of 6120 workers from factories and mining enterprises in seven districts and one district of Urumqi were determined using the stratified cluster random sampling method. The Effort-Reward Imbalance (ERI) questionnaire and the Symptom Checklist-90 (SCL-90) were used to evaluate the effects of occupational hazard factors on job stress and mental health of workers. The propensity score analysis was used to control the confounding factors. The occupational hazards affecting job stress of workers were asbestos dust (OR=1.3, 95% CI: 1.09-1.55), benzene (OR=1.25, 95% CI: 1.10-1.41), and noise (OR=1.39, 95% CI: 1.22-1.59). The occupational hazards affecting the mental health of workers were coal dust (OR=1.19, 95% CI: 1.02-1.38), asbestos dust (OR=1.58, 95% CI: 1.32-1.92), benzene (OR=1.28, 95% CI: 1.13-1.47), and noise (OR=1.23, 95% CI: 1.07-1.42). Different occupational hazards have certain influence on job stress and mental health of factory workers and miners. The enhancements in occupational hazard and risk assessment, occupational health examination, and occupational protection should be taken to relieve job stress and enhance the mental health of factory workers and miners.

“…Inhalable particles are those that enter the nose or mouth, and respirable particles are the mass fraction of inhaled particles that penetrate the unciliated airways [15]. Coal dust contains organic maccerals and inorganic minerals (e.g., quartz silica, phyllosilicates, and sulfides) that could lead to respiratory cell damage [16]. Respirable coal dust particles can overcome the filtration system of the oral and nasal airways due to their small size, and can transport to the lower region of the airways [17].…”

“…Long-term occupational exposure, and high concentration of coal dust and toxicity of respirable coal dust particles, leads to a variety of pulmonary diseases for coal mine workers. Coal workers' pneumoconiosis (CWP) [16], silicosis [5], chronic obstructive pulmonary disease (COPD) [21], and mixed dust pneumoconiosis [5] are the most common respiratory diseases for coal mine workers. Silicosis is a dangerous respiratory disease mainly caused by respirable crystalline silica [22].…”

Occupational exposure limits for respirable coal dust are based on exposure during working hours, but coal miners may experience additional community-based exposures during nonworking hours. We analyzed Australia National Pollutant Inventory (NPI) data for the years 2008-2018 to estimate air pollutants (metals, nitrogen oxides, particulate matter ≤ 10 micrometers (PM10) and ≤2.5 micrometers (PM2.5)) originating from coal mines. PM10 levels from community-based air monitors in Queensland and New South Wales were also compared between mining and nonmining communities. Results indicated that tons of coal mined increased over the study period, and that levels of particulate matter, metals, and nitrogen oxides increased significantly over time as well. Coal mines accounted for 42.1% of national PM10 air emissions from NPI sites. PM2.5 from coal mines accounted for 19.5% of the national total, metals for 12.1%, and nitrogen oxides for 10.1%. Coal mining occurred in 57 different post codes; the 20 coal-mining post codes with the highest PM10 emissions were home to 160,037 people. Emissions of all studied pollutants were significantly higher from coal mining sites than from other types of NPI sites. Results from community-based air monitoring stations indicated significantly higher population PM10 exposure in coal mining communities than in nonmining communities. The health of the public at large is impacted by coal mining, but to the extent that miners also live near coal mining operations, their total exposure is underestimated by consideration of exposure only during working hours.

“…To evaluate the health impacts of dust in underground coal mines, it is significant to understand its mineralogy and composition. Its inorganic (mineral) composition comprising of silica, phyllosilicate, carbonates and sulphides [8] and organic (macerals) components produce a broad spectrum of metallic elements that damage lungs when inhaled [9]. Worker exposure to this dust causes coal mine dust lung disease (CMDLD), coal workers pneumoconiosis (CWP) or progressive massive fibrosis (PMF) [10].…”

Coal is a major source of energy in developing countries. Its underground mining exposes workers to respirable dust containing silica, causing respiratory illness. The objectives of this study include measuring this dust and the percentage of its silica content and evaluating the prevalence of respiratory diseases among coal cutters. A walkthrough survey performa, SKC Airchek 52 (SKC Inc., eighty four, PA, USA) air sampling pumps, an anemometer, hygrometer, multi-gas detector, a thermometer and modified International Union Against Tuberculosis and Lung Disease (IUATLD) respiratory questionnaire were used to collect data from 64 workers working in 5 different mines of Chakwal District in Punjab, Pakistan. Mine E, with the lowest ventilation volumetric flow rate (18m 3 /s), has the highest dust concentration (6.10 mg/m 3 , silica content 2.699%). Conversely, mine A, with the highest ventilation volumetric flow rate (45 m 3 /s), has the lowest dust concentration (2.58 mg/m 3 , 1.33 % silica content). Survey results show that 71% of workers inherited this occupation, 94% did not smoke, 99% did not use any dust mask, 47% have diagnosed tuberculosis and 8% asthma. About 57, 48, 44 and 42 workers reported cough, phlegm, chest tightness and shortness of breath, respectively. The 89% workers were told by their physicians that dust exposure was the reason for their respiratory ailment.
