Science of empirical design in mining ground control - ScienceDirect

For thousands of years, all mine design was empirical, in the sense of being based on past experience rather than engineering mechanics. .. that vary in strength; and (3) they apply to unsupported rock, while roof bolts are universally employed in coal mines, and so the “bolted interval” must be treated as a single structure.

Model proposal for representing a deep coal mine spatial and .

A set of abstract workings for every identified function was designed. The real working model represents the actual working in mine structure. As the real working usually perform more than one function, they are constructed as a composition of abstract workings. The properties' set of a real working is a union of properties.
