Safeguards against silicosis in mining

2011-9-19  Along with coal worker’s pneumoconiosis, also called black lung, silicosis is one of the primary respiratory diseases that has damaged the mining industry since the industrialisation of drilling operations in the 20 th century.. Classified as an occupational lung disease, silicosis (which is itself a form of pneumoconiosis) is caused by the inhalation of crystalline silica dust.

Mining is bad for health: a voyage of discovery SpringerLink

2019-7-9  Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners. I look at mining and health from various personal perspectives: that of the ordinary man ...
