most of the water and methane encountered in the Oliver No. 2 Mine was present in fractures, joints, bedding planes, or in permeable rocks near the coal seam mined. However, with about 250 feet of shale, siltstone, and sandstone between the B-Seam and the E/DO- Seam, the extent and volume of water and methane cannot be predicted without drilling. One drill hole located near the mouth of the unnamed drainage west of Box Canyon, near the haulageway of the Oliver No. 2 Mine, was observed to exhaust gas and water vapor in a volume of 5 to 10 cubic feet per minute (5-10 cfm) at atmospheric pressure during field studies in October 1996. The shut-off pressure was estimated to be 20 psi. The source of the methane and water vapor was reported to be mainly from the A- and B-Seams. This would indicate that water and methane may be encountered during mining of the B-Seam in the Oliver No. 2 Mine azea."

"As discussed in Section 3.0, the moisture content of the caved and downwarped rocks controls the amount of subsidence that can be expected. In the Oliver No. 2 Mine area, and in other azeas where water might be encountered in an azea equal to, or greater than, the width of the proposed longwall panels, maximum vertical displacement may be expected to approach 0.8 times the coal-extraction thickness".

"The worst possible, but again very unlikely, underground impacts in the Apache Rocks and the Box Canyon mining azeas may be that... 2. Though unlikely, fractures filled with water and methane that were reported in the abandoned Oliver No. 2 Mine (Dutuud 1976 p. 30-34) might be encountered or intersected by the B-Seam fractured zone that may divert the water and methane to the B- Seam workings."

"The Oliver Mine, on the east side of Sylvester Gulch, reportedly encountered high ground water inflow as Sylvester Gulch was approached in 1954. There is no evidence of flow out of the adit at the present time." [Permit page 2.05-147 (November 2004)] 17.
