A fault was noted, with the downthrown side to the west. This fault was mined through in some areas, but when the same fault was found in the Orient No. 3 Mine (mine index [[0690]]), advancement was halted where the fault was encountered. The displacement was more than 7 feet. The roof near the shaft was a silty gray shale, very thinly laminated, with interlaminations of carbonaceous material. In other areas, a well-laminated dark gray shale made up the roof below the silty gray shale. The dark gray shale did not hold, and generally 2 feet of roof rock was taken down before bolting the roof. Roof falls of 5 to 25 feet were noted. Two shear bodies were found. One was discussed in IMN 72 and Reprint 1986B; see those documents for discussion of these features in more detail. Some large rolls were present in the coal, with coal riders above the main seam. In many areas of the mine, a 1- to 2-inch band of fusain at the top of the seam was present, as well as a Β½ inch stringer that was 2 to 3 inches above the fusain. A soft gray shale was between the fusain and the stringer. Clay dikes and slips were also seen in the mine.
