Mine development and secondary mining in the J seam will <br />be kept in advance of mining in the G seam (except as noted below) so as <br />to not destroy the integrity of the J seam. In the J sears mine plan, <br />entries, crosscuts, rooms, and barrier pillars will be laid out in such <br />a manner so that they will directly overlie those in the G Seam to every <br />extent practical. <br />Development of the G seam during this five year plan <br />will be for life-of-mine entries. There will be no second mining <br />(pillar extractions during the projected 29 year life of 2nd and 1st <br />East entries developed during this five year plan. Therefore, no <br />subsidence will occur; thus the p and J seams will be fully protected <br />in these areas. Please see Exhibit Goa, <br />Development of the P and J seams have been delayed <br />due to a lack of a market for these coals. When coal market conditions <br />improve and a market can be secured for these coals development of the <br />• P and J sears will be considered. <br /> <br />C-26d <br />
