摘要
南关煤业一采区断层较为发育、且走向不一,断层的相互交错切割形成多个赋存不连续、形状不规则、地质构造影响大的"边角煤资源"。现采用的长壁综合机械化开采技术不能很好地适用于构造复杂区边角煤开采,为提高回收率,矿井尝试采用连采机机械化开采回收边角煤资源。通过实践该方法不仅能有效解决边角煤的损失浪费问题、提高资源回收率,而且能够延长矿井服务年限,保障企业可持续发展。
The faults in the S1 mining area of Nanguan Coal Industry are relatively developed with different trends,which interlaced with each other and formed a number of corner coal resources with being discontinuous,irregular and remarkable fracture.The existing long-wall mining technology are not well applied to the geological condition,for the sake of recovery rate,the mine experienced the continuous mining machine.The practice not only solved the problem of resource waste for fractured corner coal,improved the recovery,but also extended the service life of the mine.
