After the deluge: Appraising the 1970 Mufulira
ABSTRACT. This article endeavours to position the Mufulira mine disaster in the wider historiography of mining in post-colonial Zambia. In the early hours of 25 September 1970, about two million tonnes of water, and slimes Dust samples were collected from the copper mines of Mopani Copper Mine plc (Mufulira and Nkana Mines). Analytical measurements employed NIOSH Method 0600 for Cross-sectional silica exposure measurements at two

The Mufulira mine has a proven and probable ore reserve of 19 million Tonnes and has at the Current copper price an expected mine life of 25 years. The main mining method in Mufulira mine began mining activity in 1933. It is located in the Copperbelt region of Zambia, with plenty of copper and cobalt restoration.

We measured the quartz content of 20 bulk settled dust and 200 respirable dust samples in a cross-sectional dust exposure assessment that is part of an epidemiological study to ascertain the risk of nonmalignant respiratory diseases among Zambian copper miners. Dust samples were collected from the copper mines of Mopani Mufulira is as famous for copper production as it is for air pollution. Most of the town’s residents are routinely exposed to sulphur dioxide fumes, locally known as ‘senta’, but it is the communities closest From ‘Senta’ to ‘Acid Fumes’: Mufulira, Mopani

The results indicate weak dust monitoring at these mines which may increase the risk of nonmalignant disease in many miners and accord with the recommendation that Zambian mining houses and the government establish crystalline silica analysis laboratory capacity and adopt dust mass concentration occupational exposure limits for more protective dust Cross-sectional silica exposure measurements at two Zambian copper mines of Nkana and Mufulira. 2008 Jun;5 (2):86-90. doi: 10.3390/ijerph5020086.

Preliminary review of mine air pollution in Zambia
Zambia has been predominantly a mining country and the copper industry has dominated the mining landscape for more than eight decades since the first commercial mine was opened in the early 1900s (RCCM, 1978; Simutanyi, 2008).To date, the mining sector is still the major foreign exchange earner for the country and the increase in the Background and Objective: Silica dust is present in almost all mining operations and can cause various health problems such as silicosis in workers. The present study aimed to determine the total and respirable dust levels and the crystalline silica content of the soil in the breathing zone of workers in Iranian mines. Mufulira Mine had 77(PDF) Cross-Sectional Silica Exposure Measurements at Two

Creep Damage Model for Rockburst at Mufulira Mine in
For over 40 years, Mufulira underground copper mine has been recording incidents of rockburst. Laboratory tests and numerical analyses were carried out to understand the rockburst mechanism at the Mufulira mine. Rockburst did not occur in the chain pillars or at the mining face, but mainly in the mining drives along diminishing Cross-Sectional Silica Exposure Measurements at Two Zambian Copper Mines of Nkana and Mufulira Patrick Hayumbu1,2*, Thomas G.
