Crucial Role Of Mineral Resources In Quebec

Diamond drill bits from global mineral exploration company Boart Longyear are having

a positive impact on iron-ore drilling operations in the remote area of Schefferville in northern Quebec, Canada.Iron-ore is the key raw material used to make steel and, as demand for steel continues to increase, the demand for diamond drilling has also increased.Many iron-ore deposits are found in the area of Shefferville, as well as eastern Newfoundland and Labrador, in Canada. However, drilling in these iron-ore formations presents many challenges, from working in harsh weather to hard ground conditions.The 09UMX stage 2 bit, from the Ultramatrix line of diamond bits, is one of Boart Longyears most versatile impreg- nated bits. The large diamonds and free cutting matrix allow it to outperform traditional impregnated bits in hard, abrasive and nonabrasive ground conditions.The George Downing Estate drillers, currently drilling for iron-ore deposits in Schefferville face tough ground conditions. Typical ground formations are 70% iron-ore with bands of chert that are hard and abrasive.These drilling conditions require a free cutting bit to stay sharp and achieve good production, as well as an abrasion-resistant matrix to attain acceptable bit life.However, the diamond bits the drillers had been using were not providing a competitive wear life and they were not staying sharp enough to deal with the hard formations.With our previous bits, our drillers were never able to achieve the proper torque owing to the bit continually polishing. The only method we had to sharpen the bits was to shut off the water, which resulted in many bits burning into the formation, says George Downing Estate drill foreman Matt Mactavish.The solution was to the use the 09UMX bits, which achieved a 200% average increase in life over the other bits in the same ground conditions. In addition, the bits did not require extreme measures to stay sharp, with the drillers able to maintain the proper torque on the rigs while sustaining a continuously sharp bit.While the drillers had been averaging a 15 m life with their previous bits, the stage 2 bits consistently achieved a bit life of between 33 m and 45 m. As a result of the performance of the UMX bits including the need to trip less often, as well as the reduction of wear and tear on their drill rigs George Downing Estates drilling operations have become more efficient and profitable. Further, the 09UMX stage 2 diamond bit is now its bit of choice for all iron-ore exploration projects.As Boart Longyears oldest customer in Canada, George Downing Estates Drilling Company, headquartered in Quebec, was founded in 1947 and has been incorporated under Federal Charter as George Downing Estate Drilling Limited since 1958. It specialises in diamond, geotechnical, environmental and soil drilling and its extensive drilling fleet covers the Ontario and Quebec regions and includes diamond drills, air rotary down-hole hammers and reverse-circulation drilling rigs.Boart Longyear is a global mineral explor-ation company with 120 years of experience in providing mineral exploration services and drilling products to the global mining industry. It also has a substantial drilling presence in water exploration, environmental sampling, energy and oil sands exploration.Headquartered in Salt Lake City, Utah, the company conducts contract drilling services in over 40 countries and provides mining products to customers in more than 100 countries. Regional offices and operations are in Adelaide (Australia), Geneva (Switzerland), Santiago (Chile) and Mississauga (Canada).In 2011, Boart Longyear stated that it expected three recent initiatives to significantly contribute to its growth in 2012 and beyond.The first is the creation of Boart Longyear Financial Services (BLFS), which offers customers competitive financing solutions for leasing or buying the companys drilling equipment. All of its manufactured drilling capital equipment can be financed through BLFS, including multipurpose, production, reverse circulation, rotary, sonic, and surface and underground coring rigs. The new service will enable the company to enhance customer service while expanding drilling capital equipment sales. At present all BLFS transactions are financed on a nonrecourse basis through third-party providers, decreasing the impact on the companys balance sheet.In terms of the second initiative, the company has recently allocated a significant amount of capital expenditure to expand its rig fleet for mine water supply and dewatering services. This investment supports both the contracted and rapidly increasing global demand for this unique and technical drilling. Boart Longyear will leverage its North American expertise to provide these services to mines in Latin America, Africa and the Asia Pacific by using in-house drilling processes developed over 30 years in the broken and unconsolidated US Rocky Mountain geology.Thirdly, Boart Longyear has started selling its sonic drilling technology, including drill rigs and other equipment, to third parties. Sonic technology produces high-quality, undisturbed core samples more quickly and with less waste than conventional methods by utilising high frequency vibratory dry drilling techniques. The proprietary sonic drilling technology has been regarded as the best in the industry for many years. Boart Longyear will soon complement its sonic product offerings with operator training services and aftermarket support, providing sonic drilling solutions for its drilling customers worldwide.As the professional manufacturer of complete sets of mining machinery, such as Impact crusher,Ore beneficiation,Cement machinery, Henan Hongxing is always doing the best in products and service.screw classifier:http://www.crusher-machine.com/27.html stone production line:http://www.crusher-machine.com/
