摘　　要：以官地矿近距离与极近距离的8#与9#煤层为研究背景,为了对其进行安全、经济的高回采率开采,采取理论计算与力学模型建立相结合的方法分析研究其回采巷道的布置方式。通过研究得出在8#煤层底板布置具有"一巷三用"的回采巷道,在此基础上,对满足合采的两层煤夹层的临界厚度进行计算,确定首采工作面采用错层位巷道布置采全厚采煤法。研究结论对官地矿及具有类似地质与开采技术情况的矿井具有一定的参考价值。In order to ensure the safety,economy and high recovery rate in the mining of 8#and 9#coal seams of Guandi Coal Mine,which are close and ultra-close coal seams,we applied theoretical calculation and mechanical model to study the roadway arrangement. According to the study a three-purpose mining roadway was arranged in the floor of 8#coal seam. Based on the arrangement, the critical thickness of the two interlayers was calculated, which were of proper conditions for joint exploitation. The mining method was also determined,in which stager arrangement was used for the full-height mining in first mining working face.
