A Novel Longwall Mining Layout Approach for Extraction of Deep Coal Deposits
As more easily mined deposits are depleted, the reserves are becoming more limited and less favorable. Deposits of coal or trona that are being longwall mined are deep and are getting deeper. Coal bursts and bumps frequently occur within development entries in longwall mining of deep mines due to high stresses. This paper presents a novel patented longwall mining layout “Longwall Mining with Sp...
متن کاملAutomation 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 کاملA Study of Mine-Related Seismicity in a Deep Longwall Coal Mine
This study involves seismic monitoring of a deep coal mine. The purpose is to examine the processes responsible for induced seismicity. A seismic network consisting of five threecomponent short-period seismometers located above the mine recorded the seismic data. The events discussed here occurred from March 1, 2009 until April 7, 2011 during the mining of three longwall panels and the data was...
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...
