Fatigue Behavior of a Box-Type Welded Structure of Hydraulic Support Used in Coal Mine
Hydraulic support is the main supporting equipment of the coal mining systems, and they are usually subjected to fatigue failure under the high dynamic load. The fracture positions are generally at welded joints where there is a serious stress concentration. In order to investigate and further improve the fatigue strength of hydraulic support, the present work first located the possible positio...
متن کاملHigh-tech coal mine canary.
High-tech coal mine canary One of coal mining's earliest systems for warning of the presence of methane gas, the canary in the coal mine, though low-tech, was extremely effective and rather easy to read: if the bird died, miners had to get out of the shaft. Today, the search for means to monitor for signs of danger continues. At an annual checkup, one could be given a whole battery of tests, ea...
متن کاملCanaries in the coal mine.
Up until 30 years ago, coalminers relied on canaries as warning systems against harmful gases and pollutants underground. The miners listened for birdsong and if the birds fell silent, then they knew there was danger to their health and to take action. Today we have much more sophisticated information and reporting on the quality of air. We know precisely the levels and composition of pollutant...
متن کاملApplication of an integrated decision-making approach based on FDAHP and PROMETHEE for selection of optimal coal seam for mechanization; A case study of the Tazareh coal mine complex, Iran
Increasing the production rate and minimizing the related costs, while optimizing the safety measures, are nowadays’ most important tasks in the mining industry. To these ends, mechanization of mines could be applied, which can result in significant cost reductions and higher levels of profitability for underground mines. The potential of a coal mine mechanization depends on some important fact...
