<br />Bear Coal Company <br />2 <br /> <br />July 27, 1999 <br />Our Primary control loop traverses through the following sub- <br />sidence stations: <br />Sequence of Survey: <br />D-11-U - Control <br />UT2 <br />U4 <br />Ul <br />U3 <br />U2 <br />U5 <br />U9 <br />UAl <br />U8 <br />D-12-U - Control <br />The following stations are monitored by sideshots, angles and dis- <br />tance. <br />U10 <br />U11 <br />U21 <br />U22 <br />U25* <br />U26* <br />U27* <br />* Additional Stations were established this May, 1994 in <br />Lone Pine Gulch. See map for location. These stations <br />are #5 Rebar with 1 1/2" aluminum caps. <br />Our subsidence and slope stability surveys up through July of <br />1990 were performed using a Wild T-2, 1 Second Theodolite with a <br />top mount K & E Autoranger Electronic Distance Meter. For sur- <br />veys performed from November of 1990 to the present date, we have <br />used a Lietz Set 2 Total Station which is a 1 Second Theodolite <br />with a Coaxial Electronic Distance Meter. Starting with the July <br />1991 survey UTE is using a new coordinate geometry software <br />program to adjust the survey data. <br />Following in Table I is a list of the stations in the main sub- <br />sidence loop with their coordinates and elevations from August, <br />1985, through July, 1994 and the resulting mean values: <br />
