Geologic Investigations of Underground Coal Mining Problems
A series of geological surveys were completed in six coal mines in connection with a Bureau of Mines research program on methane control. The aim of these surveys was to study the overall geology of the coalbed and to use the resulting data to evaluate the influence of the geological characteristics of the coalbed on safe and efficient coal extraction. Such geologic investigations can help to alleviate many mining problems. They are in advance of mining and predict sand channels that may intersect and cut out the coal. Clay veins can be located and their trend sometimes established. Thus, the high concentration of gas and related roof problems that frequently occur in conjunction with clay veins can be anticipated. A detailed map of the rock above the coalbed can be used to determine the length of roof bolts needed to anchor in competent strata.
