SME helps bring outstanding speakers to the Local Sections through the Henry Krumb Lecture Series. The program is offered to all local SME sections to enhance their appreciation and understanding of important new methods and technologies. Lecturers are selected from the professionals who present technical papers at the SME annual meeting. The Series is administered by SME and is partially funded by a grant from the Seeley W. Mudd Memorial Fund.
The Role of the Project Management Professional During Project Start-up
Abstract:A construction project can rarely conclude successfully if the start-up is poorly executed. However, there can be a sense that all that is needed to achieve construction start-up is to simply issue the construction team with a Notice to Proceed. Most industry professionals understand from either their own experience or from that of their industry friends that this is nowhere near the whole story. From the perspective of a construction management professional, lessons learned from starting up complex vertical construction projects apply very well to other project types and can be used to avoid undesirable outcomes. This presentation will highlight some lessons learned and describe a systematic, project management based approach to delivering on five key points in construction start-up, namely (1) defining the key objectives, (2) communication with the construction team, (3) client reporting (4) implementing QA/QC procedures and (5) budget and schedule management.

Resolution Copper's Underground Exploration Project Number 10 Shaft Development
Abstract:Resolution Copper Mining LLC is developing a new mining project to access approximately 1.6 billion known tons of porphyry copper resource 7000 feet below surface and mine it by block caving methods. This project will require approximately $5 billion to commence production in 2022 and take seven years to ramp up to full production of 120 thousand tonnes per day. This presentation discusses the project start up and the sinking of the first of six 7000 foot deep shafts required to access this world class orebody. Resolution's 28-foot diameter Number 10 shaft is currently 6000 feet deep and scheduled to reach full depth later in 2013. Resolution's sinking contractor, Cementation USA, uses state of the art conventional sinking methods combined with a largely local labor force to complete this record breaking shaft. Upon completion, Number 10 shaft will be the deepest shaft in the United States and the largest by volume in North America. Details of the methodology and lessons learned will be discussed in this presentation..
Tom Goodell is Resolution Copper's General Manager of Underground Development, responsible for directing all underground mining activities and shaft development work. Tom has more than 35 years of mining, engineering, project management, shaft construction and development experience. He has worked for leading national and international companies, including Redpath Corp., Battelle, Dravo Corporation and McIntosh Engineering.
Before assuming his current role, Tom spent two years overseeing Resolution Copper's shaft development progress as project manager, shaft sinking.
Before joining Resolution Copper, he spent five years as general manager for McIntosh Engineering, a global consultancy specializing in underground mining engineering and related technical services. He also worked for 10 years with J.S. Redpath Corp. as general manager of US operations. In those positions, Tom's responsibilities encompassed design, startup, operation and management of large-scale shaft and underground construction projects. His accomplishments include three shaft rehabilitation projects, management of two shaft-sinking projects and engineering design and construction of several additional shafts, tunnel and mine development projects. During his career, Tom also has provided direct input to five Rio Tinto underground projects across the United States and Canada.
Tom holds a bachelor of science degree in geology from Colorado State University. He is a past chairman of the Underground Technology Research Council and is accredited as an executive principal for contractor licenses in Nevada, California and Arizona. He also maintains a private pilot's license.

Flotation of Halite and Sylvite from Carnallite with Dodecyl Morpholine
Abstract: Carnallite recovery by reverse flotation of Halite with Dodecyl Morpholine (DDM) as collector has been applied in industry. Despite successful use in industry, there is still little research reported on DDM flotation. The surface chemistry for halite flotation with DDM collector is not clear. There is little fundamental information in the literature about halite flotation with DDM. In this presentation potash flotation practice for carnallite resources are reviewed and discussed with respect to recent research findings. The flotation response of halite, sylvite and carnallite is reported as evaluated using microflotation. The chemical features of dodecyl morpholine have been evaluated by surface tension measurements for halite, sylvite and carnallite saturated solutions. The precipitation concentration was determined by turbidity measurements. The wetting characteristics for NaCl, KCl and carnallite are also studied. Finally initial efforts were made to study the interfacial water structure using molecular dynamic simulation (MDS). The simulation results indicate that the carnallite surface is completely hydrated.

Haulage Fleet Definition Tool
Abstract:Inherently, haulage fleets are subjected to a vast amount of operating variables, many of which are highly unpredictable and hard to quantify. Thus, the mining industry experiences, at times, great difficulty in trying to define a proper fleet configuration and then project meaningful performance estimates.
To aid with this fleet definition complexity, the Komatsu Mining Division has developed a software tool that addresses haulage fleet definition and the variables common to haulage systems. This tool avoids defining finite performance figures, as typically done in like software programs, but instead illustrates performance values for variable haulage applications and fleet configurations. Thus, the user has the ability to evaluate multiple haulage scenarios without having to conduct and comprehend a series of individual analyses.
This presentation will introduce this mining system tool and its major design principles. An overview of these principles will give the attendee an understanding of the key functions and capabilities of the program. In addition, evaluation examples will be presented to further insure understanding of how this tool can be applied for a haulage application analysis.
