• 1995 Subsidence Report <br />Page 7 <br />area. Visual ~ronitoring is concentrated over areas of retreat m; n; nq with <br />particular emphasis on areas mined under low overburden. <br />A visual subsidence monitoring inspection was conducted the first week November <br />1995. Panel ZZ and Panel ZZ-1 North was .inspected. Panel X was advanced during <br />the year but no retreat m;n;ng was performed so it was not inspected. <br />No visual indications of subsidence were noted during the subsidence inspection. <br />No visual irrlications of subsidence were rated during surveying or hydrology <br />monitoring efforts for the 1995 calendar year. <br />Projected Subsidence IaQacts 1996 <br />Subsidence impacts during 1996 are projected to be minimal based upon subsidence <br />patterns established to date. Mining during 1996 is projected to occ,-ur in the <br />"Right" sections to the east of Panel X. The areas scheduled to be mined during <br />1996 axe not significantly different from areas previously mined in terms of <br />topography, geology, or mining technique and should not, therefore, exhibit <br />significantly different subsidence effects. <br />Projected Subsidence Monitoring 1995 <br />Per the conditions of technical revision 16, the Operator is rgn 'red to inform <br />the Division of selected sites proposed for surveying for the upcoming year in <br />the Annual Subsidence Report. Fbr the 1996 Calendar year, the Operator proposes <br />the following thirteen (13) sites for surveying (see Map No. 2-5 appended to <br />this report): 6, 14, 15, 16, and 95; drill hole locations 55, 65, 66, and 68; <br />structure locations in the north ~S of Section 10 which will be denoted <br />subsidence ~ronitoring points 94, 96, and 98; and the corner of Sections 9, 10, <br />15, and 16 designated point 99. The sites will be surveyed once during the <br />Y~• <br />In addition, the Operator will survey the seven (7) Pitkin Mesa Pipeline <br />monitoring locations semiannually until stability is documented. <br />• <br />
