APPROVAL FOR DRILLING OF HOLE <br />LW9-3 TO MONITOR MINE GASES PERMIT NO. C-81-018. DESERADO MINE <br />Dear Mr. Mathews: <br />This application is for a minor revision to the permit to incorporate information on previously drilled <br />emergency holes LW9-1 and LW9-2 and to drill a vent hole LW9-3 to monitor gases from the recently <br />sealed longwall area. These activities are described below. <br />Intormatton on Prevtousty DAlled Emergency Holes LYV9-1 and LW9-2 <br />As you are aware, the Deserado Mine caught on fire near the tailgate end of the longwall LW9 face. <br />All the underground mine personnel were safely evacuated and fire rescue measures were put in <br />place. One such measures was to drill two emergency holes, LW9-1 and LW9-2, to pump CO2 gas. <br />Hole LW9-1 was drilled 1351 feet deep with 6-1/4 inch diameter. Hole LW9-2 was drilled 1330 feet <br />deep with 6-1/4 inch diameter. A total of 2200 feet of new access was created. The hole locations <br />and access are shown on Map 138. The working districts were eventually sealed. We estimate a total <br />surface disturbance of 1.1 aces. <br />DAl1Ing of Hole LW9 <br />Hole LW9-3 will monitor gases from the recently sealed longwall area. The purpose of such <br />monitoring will be to assess the fire condition in the sealed area. The hole will be drilled near the <br />headgate of the face of the longwall panel 9. An attempt will also be made to lower a video camera <br />through this hole to monitor the condition of The longwall equipment near the face. Map 138 shows <br />the location and access to the hole. The hole will be 8-5/8' in diameter with an expected depth of <br />Suite #305 <br />405 Urban Street <br />lake~vood, Colorado 80228 <br />Telephone 303/988-9626 <br />ihlecapier 303/986-8147 <br />
