production rate is not feasible. On the contrary, for η>0.1, there is more diversity in
panel widths selected, and solutions maximize coal recovery, but do not prioritize pro-
duction rate. For example, consider strip 2, which is 3970ft wide. When η<1, the
solution requires the strip to be mined with four panels as opposed to three panels
