 Burning coal deep down has huge potential, untestedTuesday, October 06, 2009Burning coal underground could be one of the next breakthroughs to increase the world's energy supply, similar to establishment of Canadian oil sands, executives and academics told a conference in London on Monday.
read more » Monitoring faults could predict earthquakes: studyThursday, October 02, 2009Geologists working near California's San Andreas Fault have found a way to monitor the strength of a geologic fault — a finding which could be used to predict when a fault would fail and cause an earthquake. read more » To leach or not to leach?Wednesday, September 30, 2009In-situ leaching (ISL) or in-situ recovery was developed in the mid 1970s as a method for extracting uranium from typical roll-front type deposits located in water saturated permeable rocks that were not suitable for conventional mining. It was conceived independently in both the (former) USSR and the USA using similar approaches in engineering and technology. read more » Cost breakingWednesday, September 30, 2009Fragmentation within the mine is often overlooked as a critical element in the process and can be used to provide essential process control information. SPLIT digital fragmentation technology has been available for some time, with applications from the mine with post-blast analysis at the muck pile face through to the mechanical comminution circuit with ... read more » The road to GrasbergWednesday, September 30, 2009Until Bechtel built the first road in the early 1970s, and Freeport Indonesia subsequently developed the area, subrivers were the only access inland to the foothills of the Jayawijaya mountain range on Irian Jaya that hosts what is arguably the greatest ore complex discovered in the world to date, the Grasberg and Ertsberg copper gold deposits. read more » CCS all about finding the ‘right rocks’Wednesday, September 30, 2009The Coal Tech 2009 conference, held on September 15-16th, hosted a range of presentations on technologies including carbon capture and storage (CCS); coal-to-liquids; underground coal gasification; and syngas. read more » Frack Attack - Drilling Technique Under ScrutinyThursday, June 25, 2009Four years after a widely used but controversial oil and gas production technology was exempted from federal regulation under the Safe Drinking Water Act, Congress is taking another look at the process known as hydraulic fracturing, or fracking. read more » Walter WittkeMonday, November 10, 2008Sometime during completing my master thesis on fluid flow in fractured rock masses, I was sent by Professor Jennings to Karlsruhe University in Germany. There I met Professor Walter Wittke. read more » Rock Mechanics SoftwareFriday, January 18, 2008Here is a list of software and software providers that you may find useful in addressing rock mechanics situations at your mine. read more » Backfill ThesisTuesday, December 18, 2007Trent Weatherwax, a Masters student at the University of British Columbia, sent me a copy of his paper, A Conceptual Design of a Backfill System for Underground Preconcentration Facility. read more » Settle 3D by RocscienceFriday, December 14, 2007In the industrial area of Albuquerque is a large oil tank sitting on foundations I designed. One of the design issues was just how much the soft silty sand beneath the footing would settle. read more » Hoek on Rock MechanicsWednesday, December 05, 2007Anybody interested or involved in rock mechanics will consult Dr. Evert Hoek of his publications. A good place to start is EduMine where you will find his course series on Practical Rock Engineering. read more » FracMan - An UpdateMonday, December 03, 2007Fracman is a powerful way to model groundwater flow in mines where the flow is in the fractured bedrock. read more » FracManWednesday, March 28, 2007It seems so obvious: most mines involve cutting into rock, and rock is fractured. Therefore the stability and groundwater flow patterns of the mine opening, whether open pit or underground, will be controlled by the fractures. read more » |
