Management of safety and its impact on mine productivity in Polish coal mines
Published in Tad S. Golosinski, Mining in the New Millennium Challenges and Opportunities, 2020
The basic preventive actions to limit this hazard rely on counteracting creation of dust in the places of its origination. The main tool here is utilization of suitable water sprinkling devices mounted on the shearers as well as dust collectors on roadheaders. In addition the mine workins age sprinkled with dust. Moreover, in the case of the pneumoconiosis hazard it is important to avoid exceeding the admissible dose of dust in the lungs and to ensure that specialized individual protection equipment is used in work places.
Toxic Responses of the Lung

Pneumoconiosis is an occupational disease of the lungs caused by the accumulation of certain inorganic and organic dusts and the reaction of pulmonary tissue to the dusts. Originally, pneumoconiosis included only particulate matter in the solid phase. In recent years, however, the definition has been broadened to include aerosols other than dusts. The lesions of the pneumoconiosis are generally divided into two major categories. The first, simple pneumoconiosis, is a disorder in which there are discrete small lesions scattered throughout the lung in various profusion and with varying degrees of fibrosis. An example of simple pneumoconiosis is silicosis or coal worker’s pneumoconiosis. The second, complicated pneumoconiosis or progressive massive fibrosis, affects a small percentage of persons with pneumoconiosis. In this case, fibrotic nodules coalesce and encompass blood vessels and airways. In the past, tuberculosis was a common accompaniment of this condition.
Toxicology

Pneumoconiosis is a group of interstitial lung diseases caused by the inhalation of certain dusts and the lung tissue’s reaction to the dust. The principal cause of the pneumoconiosis is workplace exposure. The primary pneumoconiosis are asbestosis, silicosis, and coal workers’ pneumoconiosis. As their names imply, they are caused by inhalation of asbestos fibers, silica dust, and coal mine dust. We have already discussed asbestos-related illnesses. Therefore, we will discuss the remaining two in the following.18

With the improvement of the mechanization level of coal industry, the efficiency of resource extraction has increased while making the dust pollution problem in underground mines increasingly serious. The dust concentration at the mining working face of some mines even reaches 3000 mg/m3 (Jiang 1999), which far exceeds the 4 mg/m3 required by the Coal Mine Safety Regulations. Coal dust not only aggravates the damage of machinery and equipment but also has the danger of explosion, which poses a serious threat to production safety. In addition, workers who have been working in an environment with high dust concentration for a long time are more likely to suffer from pneumoconiosis. According to statistics, as many as 11,809 new cases of occupational pneumoconiosis were reported in China in 2021 (National Health Commission of the People’s Republic of China 2022), and 915,000 patients with occupational pneumoconiosis were reported nationwide, of which pneumoconiosis patients in the coal industry accounted for about 50% of the total (Quan et al. 2020). Therefore, coal dust pollution has become the focus of safety prevention work underground.

The Coal Act established requirements for chest radiographic surveillance of coal miners. Surveillance is managed by a program now called the Coal Workers’ Health Surveillance Program (CWHSP). RHD developed regulations specifying how the program operates, which can be found in the US Code of Federal Regulations at 42 CFR Part 37. Under the program, miners are offered screening at first entry into coal mining and then at approximately 5-year intervals during their mining careers. Mine operators contract with participating medical facilities, which obtain medical tests and send them to RHD. Chest radiographs are then classified for the presence and severity of changes of pneumoconiosis using a standardized classification system maintained by the International Labor Organization (ILO).10 Classifications are done by physicians called B Readers, who are certified by NIOSH as proficient in the ILO classification system. Miners are notified of their results and, if they have qualifying radiographic changes, of their eligibility to transfer to low dust jobs as specified in the US Code of Federal Regulations at 30 CFR Part 90.
Combined effect of coal dust exposure and smoking on the prevalence of respiratory impairment among coal miners of West Bengal, India

The exposure of occupational coal dust is known to be the most crucial factor for the development of pneumoconiosis.8,9 Other than pneumoconiosis, the more prevalent lung diseases among the coal miners include silicosis, asbestosis, pleural plaques, lung cancer, mesothelioma, chronic obstructive airways disease and many other respiratory disorders.10
