MNG 264 is an introduction to principles of mining operations and a study of mining methods practiced in the extraction of metallic ores, nonmetallic ores, and mineral fuels. Topics include an introduction to principles and application of geophysical prospecting; geometric models used for reserve estimation; point estimation; underground mine development; unit operations of mining; and exploitation. Unit operations include the study of rock breakage principles (i.e., drilling, tunneling, and blasting), an introduction to ground control methods, haulage systems, and auxiliary systems. Exploitation includes a detailed study of mining methods and method selection.

An introduction to probability and statistics; probability distributions for discrete and continuous random variables; joint probability distributions; point estimation; hypothesis testing; linear regression. The course emphasizes mining applications. Prereq. MA 114, MNG 264.

**EE 415G - Electromechanics** (3)

Study of electric machines and electromechanical systems. Prereq: EE 221 with a C or better and PHY 232.

**MNG 511 - Mine Power System Design **(3)

MNG 511 begins with a review of balanced three-phase circuit analysis,
one-line diagram representation of three-phase systems, and single-phase
equivalent-wye circuits. This is followed by a description of basic mine
distribution systems and the per-unit system of analysis. Subsequently,
techniques for sizing distribution and utilization components are presented,
consistent with applicable Federal regulations, culminating in a series
of homework exercises in which students size power system components, and
evaluate system performance under various unfaulted operating conditions.
Next, grounding principles and substation and safety ground bed design
are presented. Finally, configurations for substations, switchhouses, and
power centers are studied.

Introduction to modern power system practices, basic transient and steady-state stability analysis with emphasis on digital techniques. Prereq: Engineering Standing and consent of instructor.

MNG 611 is a study of transients and faults, and techniques for providing fault protection of mine power systems. The course begins with a review of mine distribution systems, one-line diagrams, and the per-unit system of analysis. Next, the objectives of power system protection are presented, followed by a study of transients and overvoltages (e.g., capacitance switching, transformer magnetizing inrush current, lightning). This is followed by computer- aided analysis of unbalanced faults and techniques for providing phase overcurrent protection. The course culminates in a project in which students coordinate phase overcurrent relays for a radial distribution system.
