A sonar survey was atternpted on recovery well WRNM 26-93-1 V without success. The <br />sonar tool was unable to be lowered below the 7" casing because of debris in the well. <br />A baseline temperature :>urvey was taken on both the injection and recovery well for <br />cavity #3. Several days after sustaining production to the plant, the mining was stopped <br />and a set of 3 (each) coal down temperature logs were taken. <br />WRN will continue to sonar survey and temperature survey the production wells as <br />required by the Mine Plan. <br />Agapito and Assoc. submitted a geotechnical study of the present roof support system <br />indicating that adequate stability was possible with cavities of 75' in width. This study will <br />• be refined as more information is received. <br />Staff in the North American organization have been utilized to create a model for the <br />development of the cavities mined by WRN. A preliminary model has been developed <br />which will be updated as more data is generated. <br />No indications of surtace subsidence were noted during 1994. Surtace monitoring of <br />ground movements will continue in 1995, and any significant changes in elevation will be <br />noted and reported to the sappropriate government agencies. <br />• 30 <br />
