摘要
淮北矿业集团双龙公司(原张庄煤矿)煤炭资源即将枯竭,为提高煤炭资源采出率,技术人员对煤柱、边角煤、三角煤等小块段工作面的顺利回采进行了相应的研究。文章以残采块段Ⅱ378工作面过联巷为例,通过采取先控制后揭露的方法,解决了联巷顶板破碎、压力大、煤壁片帮等因素给回采带来的安全隐患,为小块段工作面特殊段的顶板管理积累了宝贵的实践经验。
The coal resources in Shuanglong Company（former Zhangzhuang Mine） of Huaibei Coal Mining Group would be exhausted.In order to improve the mining rate of the coal resources,the technical personnel of the company had a related study on the successful mining of the coal pillar,corner seam,the delta seam and other small seam block in the mine.Taking No.II378 coal mining face in the mining residual seam block passing through the connection gateway as en example,with the control first and exposure second method,the safety latent dangers occurred from the factors of the broken roof of the connection gateway,high pressure,coal wall spalling and others were solved,which could be the valuable practical experiences to the roof control in the special section of the coal mining face in the small seam block.
