SECTION I:  GENERAL INFORMATION

 

 

MINING ENGINEERING AT THE UNIVERSITY OF KENTUCKY

 

            From an enrollment of 273 students in 1876, the University of Kentucky has evolved from an Agricultural and Mechanical school to a state, co­educational, nationally accredited institution composed of  15 colleges, University Extension, and Graduate School.  Currently, the University has an enrollment of more than 25,000 students on the Lexington Campus.  The university's programs are offered by nearly 9,000 faculty and staff.

 

            A small city in itself, the University has its own post office, bookstore, theaters, restaurants, barber shop, newspapers, radio station, television network, photographic service, printing plant, safety and security force, and hospital.  The 670‑acre Lexington campus has more than 100 major buildings, including the Mining and Mineral Resources Building, which was dedicated officially on April 8, 1988.

 

            With the opening of the Mining and Mineral Resources Building, of which we occupy nearly one‑half, the facilities for mining engineering have become among the most modern in the country.  The opportunities for experimentation, research, and graduate study have expanded commensurately with the tripling of the space available.  New, digitally controlled testing machines for rock mechanics, pilot‑scale‑sized ventilation tunnels with remote sensing and computer control of airflow, coal and petrography laboratories, mine electrical systems laboratory, an environmental laboratory, and an array of computers, which are networked throughout the building, all come together to support the advanced research needed for modern mining.  Inasmuch as the other major tenant of the building is the Kentucky Geological Survey, a tremendous working resource is available for research on reserves evaluation and characterization.

 

            Of primary importance among the auxiliary services provided by the University is its system of libraries. Resources of the W.T. Young Library and associate libraries include more than two million volumes and 3.2 million microform units.  In terms of numbers of volumes, the University library is one of the top 50 research libraries in the United States. 

 

            The Robert E. Shaver Library of Engineering, occupying the entire third floor of the F. Paul Anderson Tower, is a division of the University's library system.  The library has developed subject strength in such areas as nuclear engineering, mining and energy engineering, air and water pollution control, and materials science, in addition to the basic disciplines of engineering.  These subject areas, as well as allied fields, are manifested in the library's collection of approximately 31,000 volumes.  The latest findings of engineering research are reported in over 700  periodical subscriptions in the library.

 

 


LOCATION

 

            The University of Kentucky is located in Lexington, a growing city with a population in excess of 260,000 in the heart of the renowned Bluegrass region: an area of gently rolling land of unexcelled beauty with more than 300 horse farms.  Known as the thoroughbred horse center of America, Lexington has one of the finest race tracks in the country: Keeneland Race Course.  The world's largest loose‑leaf tobacco markets are located here, as are many industries and corporate headquarters, including Lexmark, Toyota Motor Manufacturing USA, Inc., Ashland Oil's Valvoline Division, and approximately 40 coal-related companies.

 

            Lexington, only 80 miles south of Cincinnati on Interstate 75 and 83 miles east of Louisville on Interstate 64, is less than a one‑day drive from all major metropolitan centers in the eastern and Midwestern areas of the country.

                                                                                                                                               

            Because the University of Kentucky is located in Lexington, its Department of Mining Engineering has the advantage of being located at the center of the state that is a leading producer of coal.  The benefits resulting from the dominance of its coal industry are seen further by its location midway between the Appalachian Coal Basin (Eastern Kentucky) and the Eastern Interior Coal Basin (Western Kentucky).  Among mining people, Lexington is humorously referred to as the world's largest and finest coal camp.

 

            The Lexington area is so rich in heritage that sightseeing is a major attraction, encompassing more than 200 years of living history.  The presence of the University of Kentucky has enhanced the area, with a proliferation of functions ranging from the A.B. Chandler Medical Center to Rupp Arena, one of the world's largest basketball arenas, with a seating capacity of 23,600 fans.  Kentucky's sports prowess is a matter of permanent record and is highly visible in the national sports archives.  Other significant features include Transylvania University, the oldest institution of higher education west of the Allegheny Mountains; Lexington Theological Seminary; Kentucky Episcopal Seminary; and Ashland Baptist College.  Lexington has the largest Community Concert Association in the country, where renowned artists and speakers appear regularly.  Of great interest are the Lexington Philharmonic Orchestra, a strong chamber music series, the Lexington Ballet, and Arts Place.  Lexington is also a strong theater town, served by several regular companies and various touring groups.

 

            The climate is moderate with cool plateau breezes, cool summer nights, and no prolonged periods of heat, cold, rain, wind, or snow.  Kentucky abounds in facilities that appeal to those who like the out‑of‑doors.  Its outstanding system of State parks, together with the Daniel Boone National Forest, provide boating and associated water sports, fishing, hiking, camping and horseback riding.  The famous Red River Gorge area of the Daniel Boone National Forest, a favorite of backpackers and canoeists, is only 50 miles by expressway from Lexington.  Kentucky has good canoeing and white water rivers, and is famous for its caves and natural bridges.  The Bluegrass region is one of the best areas in the United States for biking as it has a vast network of paved country roads from which to choose.

 

            The optimal blending of the old with the new, together with the history, location, and resources available at the University of Kentucky, results in an ideal environment for the scholastic and professional development of the serious mining engineering student.

 

 

COLLEGE OF ENGINEERING

 

The University of Kentucky’s engineering and computer science faculty, numbering approximately 140, are nationally and internationally recognized.  Among current and emeriti faculty, one is a member of the National Academy of Engineering, more that 20 have received the Presidential Young Investigator or CAREER Development Award from the National Science Foundation, and more than 25 are fellows in one or more professional societies.  Twenty-three endowed faculty positions have been committed to support faculty who are nationally recognized for their excellence in teaching and distinguished scholarship. 

 

            The College includes eight centers and consortia, including the Kentucky Transportation Center, the Center for Robotics and Manufacturing Systems, the Consortium for Fossil Fuel Liquefaction Science, Vibro-Acoustics Consortium, Painting Technology Consortium, the Center for Aluminum Technology, the Center for Micro-Magnetic and Electronic Devices, and the Electron Microscopy Facility.  The College is also affiliated with the Center for Applied Energy Research, Advanced Science and Technology Commercialization Center, the Center for Biomedical Engineering, and the Laboratory for Advanced Networking. 

 

 

DEPARTMENT OF MINING ENGINEERING

 

            The University of Kentucky's Department of Mining Engineering has the distinction of being both among the oldest and newest programs of its type in the nation.  It is one of the oldest in that the program was founded as the School of Civil and Mining Engineering in 1866; newest in that it was only 1982, after a varied history of change reflecting conditions in the mining industry, that the department was upgraded from a transition program in Civil Engineering to departmental status.

 

            In 1910, a college was established and given the name Mines and Metallurgy, but seven years later the college was amalgamated into a department within the College of Engineering.  In 1966 the mining department was realigned with Civil Engineering.  In 1977, the University Board of Trustees authorized the re­establishment of Mining Engineering as a separate and distinct department.  In 1988, the Department moved to the Mining and Mineral Resources Building.

 

            In keeping with its history and the renewed emphasis of the University's commitment to mining engineering, a distinguished national and international faculty has been assembled.  Hence, in a continuing pursuit for excellence, the University of Kentucky's traditional land‑grant teaching, research, and service function is expanded further through the addition of faculty members recruited from among the world's finest mining programs.  This faculty gives the Department of Mining Engineering an increased academic capability to become a leader in both the State's and the nation's minerals industry.


STATEMENT OF CAPABILITIES

 

            The Department of Mining Engineering at the University of Kentucky has been favored with an excellent faculty, a sufficiency of space, and an abundance of modern equipment.  This document attempts to describe succinctly the Department's capabilities in research and development for the benefit of potential research collaborators and sponsors.  In summary, the mining faculty has access to 25,259 square feet of space and to equipment with an original purchase value in excess of $1.6 million.  They are served by an elaborate but flexible computing network containing personal computers, an office LAN, and an integral bridge to the College of Engineering and university computing environments.  There is unlimited electronic mail access.

 

            Although described separately, the facilities of the UK Center for Applied Energy Research, CAER, are readily available to departmental researchers.  A number of completed cooperative projects point to the open relationship between the Center and the Department.  The CAER is a 60,000 square foot facility containing over $7 million in process development and analytical equipment.
