Today we have much more sophisticated information and reporting on the quality of air. We know precisely the levels and composition of pollutant...
متن کاملGlobal Trends in Coal Mine Horizontal Stress Measurements
Knowledge of in situ stresses is fundamental to many studies in earth sciences, and coal mine ground control is no exception. During the past 20 years, it has become clear that horizontal stress is a critical factor affecting roof stability in underground coal mines. The theory of plate tectonics and the World Stress Map (WSM) project has been extremely helpful in explaining the sources and the...
متن کامل8-isoprostane as Oxidative Stress Marker in Coal Mine Workers.
This study was to investigate whether working in conditions of elevated concentrations of mine gases (CO2, CO, CH4, DMS) and dust may result in oxidative stress. Coal miners (n=94) from the Velenje Coal mine who were arranged into control group and three groups according to a number of consecutive working days. 8-isoprostane as a biological marker of oxidative stress was measured in exhaled bre...
