To mine safely and efficiently, working conditions must be systematically defined. Their uniqueness distinguishes mining from other engineering professions. The "worst case" in underground mining is delineated and termed "encumbered space", since it "seriously impedes motion or action." Working space is often inherently hazardous, transitory, and expensive. It is also tight, distorted, congested, isolated and inaccessible, of poor quality, and deteriorating. These adverse conditions endanger personnel, damage mobile equipment, and affect all activities, even on the surface. The conditions are isolated, reorganized, and characterized in this paper using the fundamental engineering dimensions: matter, space, and time. Consideration is also given to people, money, and purpose. An integrated and intensive effort is made to define mining conditions. Comprehensive tables are presented, with attention paid to "disaster potentials." Examples of encumbered space in mining activities and methods are cited.
