Thank you for your interest in information from the Kentucky Geological Survey Coal Borehole Database. These data are based on records supplied to KGS by private coal or land companies, as well as other state and federal agencies. While the staff of KGS has made every effort to ensure that the data reflect information on file, the Kentucky Geological Survey makes no warranty, expressed or implied, concerning the accuracy or validity of these data. The user assumes all liability for any losses or damages that may be incurred through any use or application of these data. Users are requested to notify KGS upon discovery of any errors in the data supplied. The format for rock descriptions includes the driller's or geologist's English description (in some cases, alpha-numeric codes were used) and an equivalent numeric rock code. A list of these codes and their standard English equivalents is available. Numeric rock codes are based on the system described in core logging manuals by Ferm and Weisenfluh (1981) and Ferm and Smith (1981). Copies of these photographic guides can be obtained from the KGS Public Information Center at the University of Kentucky by calling 859-257-5500, x124 or toll free 877-778-7827. Borehole records may contain coal bed correlations determined by KGS geologists. A list of coal bed abbreviations for the Eastern and Western Kentucky coal fields is also available. Users should use independent means of verifying these interpretations. If you have any additional questions or would like to supply information that would improve the data's accuracy or completeness, please contact Jerry Weisenfluh, Bethany Overfield, or William Andrews at the Kentucky Geological Survey at 859-257-5500.
