Refuge chambers are new devices for underground coal mines that provide approximately 96 h of breath­ able air, water, food, and supplies in the event of an emergency where miners are unable to escape. Researchers at the National Institute for Occupational Safety and Health (NIOSH) developed a training program to prepare miners for what to expect psychologically and physiologically inside of a ...

BACKGROUND Tuberculosis is epidemic among workers in South African gold mines. We evaluated an intervention to interrupt tuberculosis transmission by means of mass screening that was linked to treatment for active disease or latent infection. METHODS In a cluster-randomized study, we designated 15 clusters with 78,744 miners as either intervention clusters (40,981 miners in 8 clusters) or con...

In recent years, Bitcoin, a peer-to-peer network based crypto digital currency, has attracted a lot of attentions from the media, the academia, and the general public. A user in Bitcoin network can create Bitcoins by packing and verifying new transactions in the network using their computation power. Driven by the price surge of Bitcoin, users are increasingly investing on expensive specialized...

Vich, Z., Novosad, F., and Brychtova', V. (1970). Brit. J. industr. Med., 27, 287-290. Erythrocytes of uranium miners: the activity of the pentose phosphate pathway. The functioning of erythrocytes was studied by determination of the activity of the pentose phosphate pathway in 431 individuals 221 uranium miners, 42 employees of a uranium ore trimming station (30 of whom were exposed), 36 forme...

The prevalence at death of carcinoma of the lung in miners and ex-miners has been compared in those with and without pneumoconiosis at necropsy. The prevalence of 11.4% in the group as a whole is no greater than that in the male population in North-west England. Carcinoma of the lung was present in 62 (13.1%) of those without pneumoconiosis and in 52 (9.8%) of those with pneumoconiosis. The mea...

Twenty-five histocompatibility antigens have been measured in 100 coal miners with pneumoconiosis attending a pneumoconiosis medical panel and the results compared with a panel of 200 normal volunteers not exposed to dust. Chest radiographs were read independently by three readers according to the ILO U/C classification. On a combined score, 40 men were thought to have simple pneumoconiosis and...

A survey of respiratory symptoms, lung function tests, and chest radiography was carried out among the fluorspar miners of St. Lawrence, Newfoundland, in whom the incidence of carcinoma of the lung (De Villiers and Windish, 1964) had previously been shown to be 25 times greater than for the rest of the province. The incidence of pneumoconiosis among the exposed population was low (1-93%) and th...

Due to safety and ethical issues, traditional experimental approaches to modelling underground risk behaviours can be costly, dangerous and even impossible to realize. Based on multi-agent technology, a virtual coalmine platform for risk behaviour simulation is presented to model and simulate the human-machineenvironment related risk factors in underground coalmines. To reveal mine workers’ ris...

The authors investigated renal damage in 45 mercury miners under conditions of relatively short and low-level exposure to elemental (metallic) mercury vapour (Hg0). The analysis included urinary mercury, immunoelectrophoresis of urinary proteins, immunofixation and high-resolution electrophoresis, quantitative analysis of urinary albumin, and urinary alpha 1-microglobulin before and after expos...
