Tanzania explores new technologies to promote safer mining

The dust-suppression technologies aim at addressing the problem of dust created by blasting, hauling roads and processing plants.

High-pressure mist systems and fog cannons have been introduced by Dust-A-Side, a South African Company to reduce airborne dust.

The cannons minimise water usage, while also effectively controlling dust.

Chief Operating Officer for Africa at Dust-A-Side, David Vander Linde said the new technology will improve visibility and safety for people who working in mining areas.

A miner who has worked for decades expressed optimism about the impact of the technology on the sector.

“With the world focusing on reducing emissions, Tanzania’s mining sector must alighn with these standards. These dust suppression technologies can help us reduce our water and chemical consumption while improving working conditions,” John Matinyi was quoted.

The move comes amidst rising concerns about climate change and health risks for residents and workers in mining communities.  

The situation leaves residents and workers exposed to harmful particles including PM 10 which has been linked to severe respiratory illnesses, silicosis and in some extreme cases, lung cancer.

Water tankers and trucks have for the longest time, been used to control the dust but the results, according to a former employee at the Bulyanhulu Mine, are very little.

“While we have been using water trucks to control dust, the results are far from ideal. The dust persists, especially on haul roads, making it difficult to maintain a healthy work environment,” Thobias Mbena told The Citizen.

The innovations also align with Tanzania’s broader environmental, social and governance (ESG) commitments.
