direct measurements of the hydrologic properties of the coal, estimates have been made. Transmtssivirv (T) and <br />storativity (S) values for equivalent coal beds at the nearby Northern Coal Mine were obtained (refer to Table 74, Coal <br />• Bed Hydrology Data - Northern Coa] Company). SpeciSc yield (Sy) was estimated to be 0.10. Although [he coal <br />thiclrness (b) can vary, an average thiclaess of 12 feet was used. These values were then applied to the McWhorter <br />method and used to try to duplicate the past measured inflows in the No. 9 Mtne.
