Simplified Cost Models For Underground Mine Evaluation A Handbook For Quick Prefeasibility Cost Estimates - Revised Edition, Thomas W. Camm, Scott A. Stebbins
Simplified Cost Models For Underground Mine Evaluation A Handbook For Quick Prefeasibility Cost Estimates - Revised Edition, Thomas W. Camm, Scott A. Stebbins
Mining Engineering
This handbook provides simplified cost models for evaluating underground mines. Regression analysis is used to generate capital and operating cost equations for each model in the form Y = AXB, where Y is the cost estimated and X is the assumed production capacity in tonnes per day. A and B are constants determined by the regression analysis. Equations are developed for operating costs in five subcategories: equipment operation, supplies, hourly labor, administration, and sundries. Subcategories for capital costs are: equipment purchase, preproduction underground excavation, surface facilities, engineering & management, contingency, and working capital. Cost models are developed for eight underground …

Luck & Skill: Black Swans & Machiavelli's Ideas On Power, Fortune, Virtu, Thomas W. Camm
Luck & Skill: Black Swans & Machiavelli's Ideas On Power, Fortune, Virtu, Thomas W. Camm
Mining Engineering
We hear all the time about the value of hard work and perseverance, and the part they play in the professional life of successful people. What we do not hear so much about are the many professionals who work hard and persevere, yet never seem to quite reach the level of success they aim for. Some current authors are beginning to give more attention to the part luck/black swans/outliers play in success. This is not a new phenomenon, Machiavelli had a lot to say about it back in the Renaissance. So how can knowledge of this dynamic help in a …
All-In Sustaining Cost Analysis: Pros And Cons, Asseu Gilbert Yapo, Thomas W. Camm
All-In Sustaining Cost Analysis: Pros And Cons, Asseu Gilbert Yapo, Thomas W. Camm
Mining Engineering
All-in sustaining cost is a metric used by mining companies to reflect the cost of gold mining in a consistent format useful to both investors and mining professionals. Cost reporting focused on the direct cost of mining and processing ore was summarized in the non-GAAP cash cost developed by the Gold Institute in 1996. In 2013, a group of mining companies, working with the World Gold Council, developed a more inclusive approach to reporting costs designed to solve the dilemma of showing a more comprehensive reflection of recurring costs involved in producing gold, without discouraging investors.
Managing Engineering Talent: Unique Challenges To Optimize The Best And Brightest, Thomas W. Camm, J. C. Johnson
Managing Engineering Talent: Unique Challenges To Optimize The Best And Brightest, Thomas W. Camm, J. C. Johnson
Mining Engineering
Most engineers are bright, hard-working, reliable, and prefer to avoid conflict. An engineering curriculum tends to self-select these characteristics. By most standards, you would expect workers exhibiting these traits to require minimal supervision. But is this true? Is this how most current engineering managers lead? Looking at some current theories on leadership combined with personal anecdotes, this presentation will look at some common misconceptions about leading engineers.
Embrace The Unknown: Stop Saying “It’S Too Hard” And Start Embracing Uncertainty In Your Mine Plans, C. Roos
Embrace The Unknown: Stop Saying “It’S Too Hard” And Start Embracing Uncertainty In Your Mine Plans, C. Roos
Mining Engineering
Nearly every input to a mine plan is based on an estimate. The estimates may be from sample data, historical information, models, or personal opinion, but in all cases, these values are simply expected values (means). In real life, we do not get to iterate the exact conditions at our mining operation many times to ensure that that average value is attained. The expected value also tells us nothing about the spread of values that that input might take on. The result is a significant amount of unquantified uncertainty in our mine plans. Unfortunately, it is often too expensive or …

Evaluation & Selection Of Novel Surveying Systems For Use In Surface Coal Mining, M. Drake, C. Roos, P. Conrad, T. Stack
Mining Engineering
This paper presents the evaluation Montana Tech completed for the Western Energy Company Rosebud Mine relating to the benefits of survey data collected using novel technologies over traditional methods for topographic surveys. These technologies include Unmanned Aircraft Systems (UAS), photogrammetry, and laser scanning/LIDAR. Utilizing these technologies, large areas such as reclamation areas and cast blasts can be surveyed in a timely manner for use by the mining operation. The areas that were evaluated were the improvements in the safety of employees and the time required to collect data. In addition, there is also a potential cost savings for the operation, …
Determine The Potential Drill Utilization Improvements And Rock Fragmentation Requirements Using Directional Drilling In A Coal Mining Overburden Highwall Application, K. D. Dill, S. D. Rosenthal
Determine The Potential Drill Utilization Improvements And Rock Fragmentation Requirements Using Directional Drilling In A Coal Mining Overburden Highwall Application, K. D. Dill, S. D. Rosenthal
Mining Engineering
This project analyzed the efficiency of incorporating the use of directional drilling technology into coal overburden blasting. Directional drilling is currently in use in the petroleum industry and it is believed that it will be a valuable asset in the mining industry. This project has shown that directional drilling can be a viable technology for use in the coal overburden removal process resulting in increased drill utilization and potential for cost savings. Future work regarding blasting and geotechnical evaluation should be performed to solidify the concept.
Pseudo Leadership And Safety Culture, Thomas W. Camm
Pseudo Leadership And Safety Culture, Thomas W. Camm
Mining Engineering
Search Amazon.com using the keyword “leadership,” and you are rewarded with a list of over 144,000 titles. There is no shortage of books and articles, many of them well written, with excellent ideas. So why is there still a constant cry for effective leadership in organizations? Often, the person in charge has personal blinders that prevent them from seeing or understanding how to implement the newest leadership idea or method. Either deliberately or subliminally, there is a disconnect from learning about leadership, and actually modelling and implementing what has been learned. Some current research in leadership theory can provide insight …
Management Challenges In Nurturing A Safe Work Environment, Thomas W. Camm
Management Challenges In Nurturing A Safe Work Environment, Thomas W. Camm
Mining Engineering
As engineers, we are trained to use logical, rational problem solving to insure our mines operate at maximum efficiency. We tend to use the same technical approach to design safety into all mining systems. This works well for machines, but not so much for the human component. Recent insights in the field of behavioral economics provide useful ideas for addressing the fact that we are driven by emotions more often than by rational thought. Understanding the nonrational aspect of human behavior is an important piece of any safety system design.

What A Ride: Mining Industry To University, Scott Rosenthal
Mining Engineering
This paper will share my ‘shift in career direction’ journey from corporate mine engineer, with 31 years of mining various commodities with a wide range of responsibilities in a variety of countries, to the world of academia. There are times in one’s career that a change is required, albeit perhaps not as drastic of a change as moving to teaching. This paper will share how the transition arose, the decision to make the change, the challenges of the first year in academia, and the journey within academia going into the second year.

The Dark Side Of Leadership: Dealing With A Narcissistic Boss, Thomas W. Camm
The Dark Side Of Leadership: Dealing With A Narcissistic Boss, Thomas W. Camm
Mining Engineering
Some of the defining characteristics of narcissists include a grandiose sense of self-importance, preoccupation with success and power, a sense of infallibility, and a supreme confidence in their ability and intelligence. Ironically, many of these characteristics are rewarded in business organizations, which may explain why there seems to be so many narcissists in management positions. Assuming we will be dealing with narcissists throughout our career, it makes sense for us to understand what makes them tick, and more importantly what we can do to work with them in a constructive manner.
Power And Politics In Organizations, Thomas W. Camm
Power And Politics In Organizations, Thomas W. Camm
Mining Engineering
Aristotle made the observation that man is a political animal. Engineers often like to think they are above the fray when it comes to organizational politics, but most organizational theorists believe politics is a fundamental dynamic in any group. This paper examines the various ways that people use power within organizations to negotiate the political interactions in the work place.

Simplified Cost Models For Prefeasibility Mineral Evaluations. U.S. Bureau Of Mines Information Circular 9298, 35, Thomas W. Camm
Mining Engineering
In this U.S. Bureau of Mines report, mine and mill cost models are presented to make quick estimates of the cost to develop mineral deposits in the desert region of the Southwest United States. Regression analysis was used to generate capital and operating cost equations for each model in the form Y = AXB, where Y is the cost estimated and X is the assumed daily capacity in short tons. A and B are constants determined by the regression analysis. Each is broken down into 11 subcategories to facilitate escalation of costs for inflation and to increase their versatility in …
