West Elk Mine <br />Minnesota Reservoir water with minimal affects to man -:made structures and the natural channel <br />walls. <br />Detained Descr4ptiion oaf Darnaze •or Dhnhathonvf Reasonable Use W* cih Gould Resuft ,from <br />.SinWdence Related phenomena 205.0016e)) 016e)r bl ,(A -C) <br />Based upon the anticipated subsidence phenomena :previously described in this section, and the <br />generalcity of structures and renewable resource lands, MCC and WWE conclude that there <br />will be little, if any, damage or destruction & reasonable use within the MCC perm it area. <br />The "worst possible consequence" to the newer, wood -framed building and 'livestock enclosure <br />would be complete destruction to Mautz Cabin {now Lazy H) over the Jumbo Mountain Lease <br />area. The building that is apparently utilized as seasonal sleeping quarters for cattle operations <br />and hunting was constructed after the 5NW longwall panel was developed and longwall mining <br />in this panel had begun. The smaller "bunkhouse" building and livestock enclosure were <br />constructed after longwall mining was complete in both the 5NW and 6NW 'longwall panels. <br />They are 'located approximately over the eastern -most pillar of the 5NW longwall panel <br />headgate, near crosscut #17 and approximately '90 feet southeast of monitoring well SOM ,C - <br />72H. The landowner had been provided updated mine plans in !December 1993, and thus, was <br />aware that mining would occur under the site. <br />Another structure exists in the Dry Fork Basin and is known as Lower Cow Camp. This <br />structure is used by the cattle pool as seasonal living quarters for the range cowboy. The cabin is <br />Sowned by the USFS and leased to the Dry Fork'Cattle Pool. This cabin and related corrals were <br />inventoried and are included in Exhibits ,60 D and 73. <br />Subsidence impacts in the vicinity �of theses structures were projected based on a conservative <br />twenty-five degree (251) angle -of -draw and an overburden depth of approximately 800 feet. <br />Mining in the B Seam occurred in the vicinity of the building in late November 1'994 and had <br />progressed two cross -cuts past it by late (December 1994. The building and site were measured, <br />surveyed and photographed in early November 1994, prior to possible subsidence impacts. <br />Subsequent surveys and photographic records `were begun in early December 1994, and were <br />continued approximately weekly until January 1'995, then bi-monthly through Match 1'995, when <br />mining of the panel was completed. Regular monitoring (weekly, then bi-monthly, as above) <br />were conducted when the 6NW longwall panel was mined past this area. Maximum subsidence, <br />as ,presented in Exhibit 60, is not expected at this location, but maximum stresses are anticipated, <br />as the building .is 'located at the edge of the panel. Because MCC will compensate for, repair or <br />replace the building in compliance ;with MCMI LRB Rule 4.20.3(2); no material subsidence damage. <br />will result, as defined by,CMLRB 'Rule 2.05.6(6)(e)(ii)(A). <br />The "worst .possible consequences" from mining to hydrologic resources, hydrology monitoring <br />stations, and the many trails and unimproved U.S. Forest Service roads could be complete loss of <br />surface water resources to tl:e; e- .vot-kNi s, total destruction of the stations and total destruction <br />or blockage of the trails on roads. i,ACC Nvill repair or replace these items as discussed later in this <br />section. <br />0 &,hside-nee mollitoring Plan - 2.05. 6 ,E6J, i6b),6ii0, ;(6)I(c),(i) and,600,0, <br />2.O5-162 Revised June 2005 PRIG, Rev.
