"Of a number of long wall and long face mining methods in use in Oklahoma mines at this time, I shall outline four in this paper. Two of these methods are in use in mines which are comparatively level. The first of these is in the Kali-Inla mine near Hartshorne. The second is in the Milby-Dow Coal Company mine at Dow. The Mullen Coal Company mine near McAlester and the Hailey-Ola Company mine near Lutie are steep pitching mines"--page 1.
