THE APPLICATION OF HIGH RESOLUTION SEISMOLOGY TO THE DELINEATION OF FAULTING AND COAL SEAM THICKNESS: A CONTINUING CASE HISTORY

Anthony R. Wagner, Emerald Exploration Consultants, Inc., Austin, Texas 78759

ABSTRACT

The Wasatch Plateau Coal Field of central Utah contains many active coal mines within approximately 1000 square miles. Over 20 coal seams greater than four feet thick exist, and several are currently being mined. Structurally, the area is dissected by faults with varying offsets. The trend of these faults is usually north to northwest. In 1980 and 1981, initial seismic surveys indicated that several northeast trending faults existed. The results of those initial surveys were presented at the 1982 Rocky Mountain Coal Symposium. The highly favorable results of the initial surveys have led to several additional surveys over the last two years. The interpretation of these data has determined fault locations, coal thickness trends, and general geologic structure. This paper presents a review of high resolution seismic technology with examples of interpreted sections typifying various geologic situations that have been encountered in the Wasatch Plateau Coal Field.
