An <br /> average of fifty samples as received follows : <br /> Volatile Fixed <br /> Moisture Matter Carbon Ash BTU Sulfur <br /> 3 . 5 38 . 0 58 . 66 5 . 8 13 , 529 0 . 84 <br /> * Data provided by National King Coal , Inc. <br /> GEOLOGIC HAZARDS <br /> Geologist, David L. Gaskill , of the Conservation Division of <br /> the U.S .G. S . reported no unusual geologic hazards are known that <br /> might affect mining in the upper Menefee coal seam. He noted <br /> that the ground water tables were below the seam (See Exhibit E) . <br /> An inspection of the King Coal Mine workings and surface <br /> showed no significant faults or strata displacement . The coal is <br /> strong and pillars are structurally competent, showing a lack of <br /> squeezing (crushing ) or rib spalling - as long as entries and <br /> crosscuts do not parallel any cleat system. Mining is being <br /> planned to avoid paralleling cleat systems . The mine floor does <br /> not buckle due to stress from overburden. <br />
