“…Lignite coal is obtained by either underground or surface mining. Surface mining is a more economical method, requiring the removal of the vegetation and soil on the surface to extract the coal on the bedrock that is close to the land surface [5,6]. Such interventions, as well as the necessity to reserve large spaces for the expansion of the excavated areas and storage of excavation wastes, inevitably cause intense environmental damages such as disruption of the soil cover, land cover/land use, and habitats, an increased risk of soil erosion and floods, air and water pollution, and loss in agricultural productivity [7,8].…”

Bu çalışmada Türkiye’nin; Malatya-Arguvan, Sivas-Kangal, Kahramanmaraş-Elbistan ve Konya-Ermenek linyitlerinin piroliz özellikleri termal analiz yöntemleri ile belirlenmiştir. DTA ve TGA deneyleri, 25 ile 1000°C sıcaklık aralığına kadar, 10 ml dk-1 N2 gazı akış hızında, yaklaşık 10 mg numune kullanılarak gerçekleştirilmiştir. TG/DTG termogramları incelendiğinde nem kaybı, uçucu madde çıkışı ve mineral madde bozunmasına bağlı olarak üç farklı bölge olduğu belir-lenmiştir. Kinetik parametreleri hesaplamak için Arrhenius ve Coats-Redfern mod-elleri kullanılmıştır. Kullanılan bu kinetik modeller yardımıyla Arrhenius sabitleri ve görünür aktivasyon enerjileri hesaplanmıştır. Sonuçlar karşılaştırmalı olarak değer-lendirilmiştir. Her iki kinetik modele göre de en yüksek aktivasyon enerjisi değerleri 3. bölgede hesaplanmıştır. Arrhenius kinetik modeline göre, Konya-Ermenek linyit-inin en yüksek aktivasyon enerjisi ve R2’ye, Coats-Redfern kinetik modeline göre ise, Sivas-Kangal linyitinin en yüksek aktivasyon enerjisine sahip olduğu belirlenmiştir. Ağırlık kaybı, düşük sıcaklık bölgesinde difüzyon kontrollü, daha yüksek sıcaklık bölgesinde ise kimyasal olarak kontrol edilmiştir. Düşük sıcaklık bölgesinde akti-vasyon enerjileri yakınken, daha yüksek sıcaklık bölgesi için enerjiler önemli ölçüde farklılık göstermiştir.

Physical and chemical properties of coal and its relationship with coal workers’ pneumoconiosis (CWP) have been studied previously. However definitive conclusions have not been reached, primarily due to the complex nature of coal mine dust. It remains unclear exactly which properties of coal mine dust related to the grade of coal cause differences in the exposure–response relationship. The aim of the study is to identify the coal mine environmental factors, and personal factors affecting the development and severity of CWP. This study was a retrospective cross-sectional study and included total of 116 coal mine workers diagnosed as CWP in a tertiary hospital between January 1, 2014, and December 31, 2021. Of the cases, 77 (66.4%) worked in a hard coal mine and 39 (33.6%) worked in a lignite mine, and mean age was 60.2 ± 11.5 years. There was a significantly higher prevalence of concomitant pulmonary disease in hard coal miners compared to lignite miners (p < 0.05). There was a significantly higher prevalence of progressive massive fibrosis (PMF) in hard coal miners compared to lignite miners (p < 0.05). The value of FEV1 and FEV1/FVC were significantly lower in hard coal mine workers than in lignite mine workers (p < 0.05). As a conclusion, concomitant lung disease, presence of PMF and impairment in lung functions, which are important causes of mortality and morbidity for CWP, were found to be more common in hard coal miners than in lignite mine workers. It is critical to develop methods to determine dust control threshold values according to coal mine type and implement protective protocols in coal mines.
