working in a coal mine | effects of mining on human health

Working in a coal mine, common causes of air pollution which someone could be constantly exposed to, include particulate matter (dust particles), toxicants such as carbon monoxide (CO), as well as highly flammable gases like methane (CH4). Some of the most serious effects of working in an underground coal mine, which is likely to be enclosed and not well ventilated, include black lung disease and …

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2

Nov 15, 2017 · Coal impacts: global warming. Climate change is coal’s most serious, long-term, global impact. Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits

a model of unsafe behavior in coal mines based on game

a model of unsafe behavior in coal mines based on game

Jan 01, 2013 · A general mathematical model of coal miners’ unsafe behavior has been established from the perspective of behavioral game theory to find new ways of quantitatively studying coal mine safety management practice. This model is based on the above discussion and uses a relative theoretical model for reference , . It refers to staff choice in behavior, coal mine monitoring, and control intensity. 2. Principles of an unsafe behavior …

applying a health action model to predict and improve

Introduction: One of the most important ways to prevent work-related diseases in occupations such as mining is to promote healthy behaviors among miners. This study aimed to predict and promote healthy behaviors among coal miners by using a health action model (HAM). Method: The study was conducted on 200 coal miners in Iran in two steps

investigation of strong strata behaviors in the close

investigation of strong strata behaviors in the close

Feb 06, 2021 · Repeated mining of multiple coal seams could cause new characteristics of overburden roof migration with a high degree of uncertainty, which increases the difficulty of detecting dangerous zones with strong strata behaviors in the lower coal seams and increases the potential dangers for safe and efficient production
