Coal <br />will be logged as it is recovered. Natural gamma, high resolution <br />density, resistivity, and caliper geophysical logs will be run in each <br />hole. <br />Daily reports will be completed including information on the activity <br />of each rig-shift, hole completions, and drill hole data. <br />' 8.0 Reclamation Procedures <br />' 8.1 Drill Hole Plugging <br />All drill holes will be grout-cemented through coal-bearing strata, <br />' with cement extending 50 feet above the uppermost coal bed. The <br />remainder of the hole will be backfilled with cuttings and mud to at <br />least three feet below the surface. The hole will then be <br />' grout-cemented to the original ground surface. A 2 foot length of <br />rebar will be cemented into the top one foot of each plug hole. <br />Aluminum caps marked with the hole identification number will be <br />attached to the rebar. <br />Any underground water encountered during drilling will be recorded. <br />Should it appear that mixing of separate aquifers could occur, that <br />portion of the hole containing the water-bearing zone or zones will be <br />sealed off by cementation. Any holes flowing water will be permanently <br />sealed by cementation. <br /> <br />8 <br />
