SUBSIDENCE ~40NITORING REPORT <br />During the month of September, 1984, The Colorado Mined Land <br />Reclamation Division approved a technical revision to permit ~C-044-81 <br />authorizing the reduction of subsidence monitoring to e.n annual basis <br />for points on A, B, C, D, and F rows. The information presented in <br />this report is for the subsidence eianitoring points on row E only. <br />A trigonometric survey method was used to compile the r•av+ data. A <br />systematic error of plus or minus 0.15 feet can be anticipated. <br />There was no detectable change in elevation for points E-1 through <br />E-9. The change surveyed is the result of the systematic error pre- <br />viously discussed. <br />
