Determining the size and life of underground coal mines

Thereby, the unit cost of coal was expressed as a function of mine field dimensions, mine design ca pacity, and mine service life. The problem was then formulated as a nonlinear optimization model in terms of minimizing the unit cost of coal subject to certain constraints, and solved analytically for flat seams and numerically for inclined seams.
