As above-drainage coal reserves continue to be depleted, attention is shifting in eastern Kentucky to resources that lie at or near the drainage level. It is imperative to make the proper economic selection of an access method to these deeper reserves. For near-drainage reserves, the choice of access is between slope and box-cut. This paper offers an analytical tool to aid in choosing the appropriate method to access these near-drainage underground coal reserves.
