Marine mining on the continental shelf was first attempted in 1900 for gold off the beaches of Nome, Alaska. Attempts continued until 1990 with cutter-suction, airlift and bucket-ladder dredges. Offshore Thailand profitable production of tin resulted from clamshell, bucket-ladder and trailing suction hopper dredges. Today in Indonesia numerous bucket-ladder dredges continue to mine tin. Off the coast of Namibia and South Africa nearly a dozen large and medium sized vessels are engaged in diamond production. The obvious risk results from the working environment. Vessels and lives have been lost in the past. At best the availability of mining equipment is reduced. Leaving aside the marketing and financing aspects, otherwise the most important risks are technical. They manifest themselves as diamond production short-falls with obvious financial consequences. Bias and deficiencies in sampling equipment and procedures may result in misleading grade estimates, even serious under-estimation. Inadequate sampling in terms of sample support and density may result in over-optimistic grade determinations, especially if under-sized mining blocks are outlined. Quantitative measurement of the geotechnical characteristics of the sediments to be mined is an essential stage in a feasibility study. Without a full understanding of the bedrock profile and the overlying sediments the ease, completeness and speed of excavation during the mining process cannot be properly estimated. Both historically and at present the greatest negative discrepancies from production estimates result, not from grade shortfalls, but from significantly lower mining rates than thought possible by the operators. The learning curve in marine, production mining is steeper and longer than is generally recognised by newcomers to the industry. Examples are provided from tin, gold and diamond mining experiences.

Modem mineral exploration and development takes place within a data-rich context underpinned by a wide range of data acquisition, processing and interpretation technologies. This leads to requirements for consistent and explicit methods by which the relative risks - or success probabilities - of exploration programs can be assessed and communicated. Bayesian risk assessment methods are outlined which provide a starting point for this more rigorous approach to exploration investment.   Effective governance of information technologies becomes a core function of the modem competitive Board. As such it becomes a component of any business audit and any assessment of the quality and success potential of a company. Limited data however suggest that the average Board may be under-represented in this increasingly critical skill area.

The Aredor mine employs conventional dragline methods to exploit alluvial diamond deposits. Production began in 1984 with the policy of mining in the terrraces during the wet season and in the river flats during the dry season. Early production failed to meet predicted grades. A major geological programme to re-evaluate existing reserves was undertaken. This resulted in considerable increases in reserves in the river flats. Many of the reserve blocks included flats on both banks of the Baoule river. Methods of access into the river flats, normally flooded in the wet season, were developed to allow mining throughout the year. River diversions have been the main method used to provide access into the reserve blocks and, most importantly, to remove the risk of flooding. Aredor has carried out six main river diversions with a total length of 12 km. The diversions allowed production planning to be made on the basis of the economic evaluation of the reserve blocks, without undue regard to natural ground conditions or to seasonal factors. The Manning equation was used for the calculation of channel dimensions and gave satisfactory results. The practical aspects of the diversion preparations and flooding prevention are described

Besides receiving a plaque from the Scholarship Chairman, Alan Czarnowsky, each winner receives $750 tuition credit for the coming academic year, as well as transportation, hotel lodging and meals at convention as guests of the Institute. This latter portion is paid by each state vice president. Because this is a continuing award, the winners from the previous year also receive a second $750 for tuition credit in their senior year. A resident from each of the eight RMCMI member states is selected from among Board approved institutions. Criteria for these awards to be made in the spring annually is that the recipient (1) Is a full time sophomore student who will use the tuition credit during the junior year. (2) Be both a U.S. citizen and a resident of the member state. (3) Maintain good academic standing, be pursuing a degree in a mining related field and have an expressed interest in Western coal as a possible career path. The scholarship program includes curricula other than in the mining departments, but in engineering disciplines, such as geology, mineral processing and metallurgy. Contributions to this worthy project are tax deductible to each individual RMCMI member or his firm. Through annual donations of $100 or more, the Patrons of the Institute fund the scholarship program. A listing of current donors is found elsewhere in this book. Donations to this worthwhile program are payable to RMCMI Scholarship and may be mailed to the RMCMI Office. 3000 Youngfield Street, Suite 324, Lakewood, Colorado 80215. Profiles of the 1995 Scholarship Winners follow. [ ] ARIZONA WINNER Brad Carroll University of Arizona - Tucson, Arizona Brad Carroll's hometown is Tucson, Arizona but his summer work is in Oriskany Falls, New York where he is a quality control technician, truck driver and equipment operator for the Eastern Rock Products. Brad served as vice president and treasurer for the SMWAIME student chapter at the University of Arizona for the past three years He was assistant and mine foreman at the San Xavier Mining Laboratory near Tucson. Upon graduation Brad plans to find a job in a southwest mine. He is a totally self supporting student. [ ] COLORADO WINNER Zane Znamenacek Colorado School of Mines - Golden, Colorado Zane Znamenacek hails from a small town in Colorado - Alamosa - where he 4 was a 4.3 GPA in high school. As a student at Colorado School of Mines, he has many hobbies to ease the tension of education. Foremost among these is skiing, mountain biking, billiards and spring rugby. He hopes to further mining technologies and contribute to the industry by working in it full time. In 1997 he will pursue whatever opportunities are available to graduating mining engineers

The Roa Opencast Coal Mine is situated at the north-eastern end of the Greymouth Coalfield. It lies on an eastern flank of the Paparoa Range, 16 km north-east of the town of Greymouth on the West Coast of the South Island. Road access is via a sealed road from Blackball to Roa, then by a 5.3 km all weather, gravel road, which gains 340 m in elevation from 190 m RL at Roa to a maximum height of 530 m near the opencast.

Mine haul roads degrade rapidly due to extreme loads on suboptimal construction materials. Unmanned aerial vehicles (UAV) are suited to quantify large-area road-network conditions, such as surface roughness, defects and grade to optimize remediation of poor conditions and reduce overall costs. Mine haul roads present unique challenges, such as material type and edge characteristics, to automatic road detection that often fails, requiring manual road input. This research work proposes a new method using the road center determined by the principal curve of a haul truck’s path. Analysis grids were created from this center line. A dense point cloud from UAV photogrammetry was generated and multiple linear regression analysis was conducted on each individual grid. The root-mean-square error in each grid indicates the surface roughness, and the change of slope between grids indicates the road grade inconsistencies. This method was applied to 26 road sections, and the results were validated by images taken from the truck operator’s vantage point. Critical defects were identified including excessive pothole formation, corrugation, depressions retaining water, and narrowing of travel lane. The results demonstrate this is a valid method of road identification and quantification of road defects at a mine site.
