of observing drawdown during pumping tests
these wells is shown in Figure 6.
The typical construction of
Wells with 5-inch diameter completed in the overburden are numbered
96, 117> 122, 133, 163 and 172. Wells numbered 118, 119, 173 and 174 are
2-inch diameter wells completed in the overburden as drawdown observation
wells. Typical well construction of the 5-inch and 2-inch wells completed
in the overburden is shown in Figures 7 and 8. Well number 97 is completed
in both the overburden and the coal as shown in Figure 9. Schematic
drawings of the remaining wells are contained in Appendix A.
Seven separate determinations of the transmissivity of the overburden
were made. The wells involved in these determinations were 172, 122, 117,
118 and 119. Two determinations of the storage coefficient were made by
measuring the drawdown in wells 118 and 119 in response to pumping from
well 117. Similarly, eight determinations of the transmissivity of the
coal seam were made by running various tests on wells 137, 116, 61, 62,
and 60. Two values of the storage coefficient in the coal seam were
estimated from drawdown data in wells 60 and 62 in response to pumping
from well 61. The results of these tests are summarized in Table 1.
Details of the computations are presented in Appendix B and the raw data
in Appendix C.
