Bear Coal Company <br />6 June 20, 1996 <br />During the June, 1995 survey two new subsidence stations were es- <br />tablished. These stations will be referred to as U28 and U29. <br />See map for location. These stations are ~'6 rebar with 2-inch <br />aluminum caps. <br />The values for these stations are as follows: <br />Northing Easting Elevation <br />U28 398,859.27 1,441,903.60 7702.50 <br />U29 398,641.37 1,440,785.49 7419.98 <br />These stations will not be monitored in the regular subsidence <br />surveys. This area is to be visually inspected for signs of sub- <br />sidence. Should there be any noticeable signs of subsidence, UTE <br />will then be instructed to monitor U-28 and U-29 and then calcu- <br />late any relative movement. <br />Relative movement between surveys is shown in the following <br />Tables. <br />Table 4 Subsidence - Relative Movement <br />Period of November, 1995 to June, 1996 <br />Table 5 Subsidence - Lone Pine Gulch <br />Period of November, 1995 to June, 1996 <br />TABLE 4-SUBSIDENCE <br />SUBSIDENCE POINT CHANGES - RELATIVE MOVEMENT <br />NOVEMBER, 1995 TO JUNE, 1996 <br />Point Horizontal Distance Bearing Elevation <br />No. <br />U10 0.29 N03°40'E -0.02 <br />U11* Not Tied In This Survey <br />U21 0.16 S83°34'E +0.81 <br />U22 0.08 N82°17'E +0.79 <br />*U11 See Note Page 3 about target pole <br />
