Automation in Longwall Coal Mining - A Review
Coal is an important fossil fuel and will also be for the next decades [1]. The only way to achieve the challenges faced by the coal industry is to reduce production costs by improving productivity. Improvement of productivity has become an important goal for today’s coal industry in the race to increase price competitiveness. In recent years, underground mining method is becoming popular becau...
متن کاملAssessment of effective parameters on dilution using approximate reasoning methods in longwall mining method, Iran coal mines
Approximately more than 90% of all coal production in Iranian underground mines is derived directly longwallmining method. Out – of – seam dilution (namely 20–30%) is one of the essential problems in these mines.Therefore the dilution can impose the additional cost of mining and milling. As a result, recognition of the effectiveparameters on the dilution has a remarkable role in ind...

متن کاملFossil hunting in coal mines.
At the northern tip of Colombia, Jonathan Bloch hunts for fossils in the midst of spontaneous combustion fires, noxious gases laced with foul-smelling sulfur, rock-shattering explosions, and some of the largest machines in the world. “It is a weird place to work,” Bloch admits, an associate curator of vertebrate paleontology at the FloridaMuseum of Natural History, although he says he feels saf...
متن کاملEvaluation of the approach to respirable quartz exposure control in U.S. coal mines.
Occupational exposure to high levels of respirable quartz can result in respiratory and other diseases in humans. The Mine Safety and Health Adminstration (MSHA) regulates exposure to respirable quartz in coal mines indirectly through reductions in the respirable coal mine dust exposure limit based on the content of quartz in the airborne respirable dust. This reduction is implemented when the ...
