An Investigation into the Development of Thermal Management Policies for Underground Metal Mines in the United States
… the mines greatly depend on the quality of the underground thermal climate. The costs associated with a substandard thermal work environment can be significant. Within the last decade, sliding commodity prices and pressure on mine operators to increase production output resulted in increased …

Színtér a színtérben
… az a célom, hogy a debreceni kortárs underground metalzenei színtér mint lokális és lokális műfaji zenei közösség esetében megtaláljam azokat a kapcsolódási pontokat, mellyel igazolható a színtér kettős jellege: a műfaji színtér egyszerre integrálódik és el is különül a helyi lokális …

Real-time diesel particulate matter monitoring in underground mine atmospheres, association with the standard method and related challenges
… equipment is a significant component of underground mining operations. Miners' exposure to diesel exhaust is harmful. The standard Diesel Particulate Matter (DPM) monitoring method (NIOSH 5040 method) has limitations that preclude rapid DPM estimation and detailed understanding of DPM …

Reliability estimation and risk-cost optimisation of underground pipelines
… any civil engineering design. A large section of underground pipelines in the UK are classified as structurally deficient and functionally obsolete. Due to low visibility, condition assessment and rehabilitation of underground pipelines are frequently neglected until a catastrophic failure occurs. …

Applications of Thermal and Laser-Based Methods for Monitoring Airborne Particulates in Coal Mines
… methods to monitor airborne particulates in underground coal mines. Specifically, coal and mixed mineral mine dust, as well as, diesel particulate matter (DPM). These particulates have historically, and continue to have, significant health impacts on underground miners. Chapters 1 and 2 of …

Continuous DPM Monitoring in Underground Mine Environments: Demonstration of Potential Options in the Laboratory and Field
… including cardiovascular and pulmonary disease. Underground miners typically have the highest DPM exposures compared to other occupations. This is because many mines are characterized by confined work spaces and large diesel equipment fleets. Exposures can be a particularly high hazard in large …

Improving Health and Safety at Surface and Underground Mines by Implementing Emerging Technologies Coupled With Geotechnical and Climatic Modeling
… part of any mining operation - surface or underground. When deficiencies are identified, they usually lie with the factors that contribute to unsafe and unhealthy working conditions. The health and safety focus for modern underground mines involves improving the subsurface thermal climate …
