摘要
华兴公司14130炮采工作面向前推进时,上段局部遭遇构造带,煤层分离、尖灭,形成薄煤带（厚0.1~0.4 m）,给正常回采带来较大困难。经过分析研究,结合自身实际,提出了采后沿空留巷的方案。实践证明：实施该方案后成功避开了薄煤带,提高了生产效率,经济效益明显,实现了矿井的安全高效、绿色快速回采。
When 14130 blasting working face of Huaxing Company was putting forward,parts of the upper suffered the tectonic zone,coal separated and tipped off,thin coal seam（0.1~0.4 m） formed,and brought about great difficulties for coal′s normal recovery.Based on analysing and research,combined with actual situation,the gob-side entry retaining proposal has been adopted.Practice has proved that：it successfully kept away from the thin coal seam,the productivity was improved,and the economic benefit was obviously increased,which fulfilled the demand of safe,high efficient,green and fast recovery.
