近期,枣矿集团柴里煤矿运用“综采工作面跨采极薄岩柱下巷道综合加固”技术,解放了300余万t的煤炭资源,有效延长了矿井寿命。在该矿综采工作面跨采南翼3条上山最小岩柱仅为3.5m,工作面在上方推过时,不但会造成巷道的严重破坏,而且有可能因应力集中、岩柱破坏,造成综采支架下沉停面停产的危险,开采难度非常大,在该矿开采历史上尚属首次。该技术被中国能源化学工会全国委员会评为科技创 Recently, Zhaji Mining Group Chaili Coal Mine used “fully mechanized coal mining under the ultra-thin rock pillar of fully mechanized coal mining face” to liberate more than 3 million tons of coal resources, effectively extending the life of the mine. In the mine fully mechanized mining face across the southern wing of the three smallest uplift pillars only 3.5m, working face pushed in at the top, not only will cause serious damage to the roadway, and may be due to stress concentration, the destruction of rock columns, resulting in comprehensive Mining shelves down stop stop danger, mining is very difficult, for the first time in the mining history of mining. The technology by the China National Energy Chemical Union National Committee as a technology innovation
