Silica dust in the workplace At least 600900 people die each year from workrelated disease in New Zealand. Exposure to a form of silica dust – respirable crystalline silica (RCS) – is dangerous and can cause serious lung disease.
Blowerdriven air provides a safe, economical and highly effective means of removing deposits such as dust, fibres, water and more – from people, product surfaces or work environments. In fact, the low pressure, high velocity air produced by our systems poses no threat to human safety and can be safely directed at virtually any part of the ...
The technology for mining in the cement industry has also been improved. Instead of conventional mining, the process known as the surface mining is adopted. It is carried out without drilling, blasting, and crushing when extracting valuable minerals. The surface mining greatly reduces the vibrations, noise and dust .

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the ...
