Modern mining practices may mitigate these hazards and reduce the risk. The literature raises concerns about lung cancer and nonmalignant respiratory diseases, but questions remain about the exposures of interest, effects of underground versus surface mining, timing and dose-response of exposures, and the effects of specific …

Within the coal mine subsample, the probability of a mine reporting a lung disease was found to be greater for underground as opposed to surface types (by 2.73 to 3.40 times) and in the Appalachian region as opposed to the remaining regions of the United States (8.00 to 9.78 times).

Second, age and mining tenure were self-reported, which could affect comparisons of tenure-adjusted disease prevalence. Finally, estimates of the prevalence of CWP and PMF included assessment of miners with underground mining experience, 155 (6.9%) of whom had ≥25% of their total mining tenure in underground mines.

Learn About Silicosis Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Industrial Dust Diseases.

Background: Exposure to respirable coal mine dust can cause pneumoconiosis, an irreversible lung disease that can be debilitating. The mass concentration and quartz mass percent of respirable coal mine dust samples (annually, by occupation, by geographic region) from surface coal mines and surface facilities at U.S. underground mines during …

how easily will the ore break. Standard mining techniques include: cut and fill or drift and fill; ore is mined and the stope filled with tailings, raising the level of the mining. shrinkage stoping – similar to cut and fill except the ore is blasted and left in place and used as a mining platform. Most of the ore stays in the mined area (the ...

The most significant group of diseases and risks faced by the miners of Australia are MDLDs, including: 1. Pneumoconiosis. Pneumoconiosis refers to a group of lung diseases caused by inhaling certain dust particles over time, causing an adverse reaction in the lung tissue. The most common Pneumoconiosis for miners are:

The demand for minerals is increasing unceasingly throughout the world. In order to meet the demand, underground mines are operated at greater depths using high capacity machinery [1, 2].Increasing mining depth and upgrading of mine mechanization are the prime causes of heat hazard, which is a major concern in deep underground …

Miners work long hours per day and many days per week. The recent trend is that this massive fibrosis can occur in as little as 5 years of mining underground. This massive fibrotic disease occurs to a greater extent in certain mines in ia, West ia and Kentucky but can also occur in surface mines. Why do these hot spots of PMF occur?
