摘　　要：以冀中能源股份有限公司章村矿2号煤层4231采区3109薄煤综采工作面为研究对象,根据该采区涌水量大的特点,进行了大水条件下沿空留巷技术研究,提出了单体支柱配合铰接顶梁的沿空留巷支护方法。该支护手段效果显著,沿空留巷顶底、两帮变形量均控制在1 000 mm以内,解决了大水条件下沿空留巷支护难题,取得了较好的经济效益,为类似情况提供借鉴经验。Zhangcun Mine No. 3109 comprehensive mechanized coal mining face coal-thin zone in No. 2 coal seam 4231 mining area of Jizhong Energy Resources Corporation Ltd. was taken as the study object, based on the characteristic of large mine discharge, the research on the gob-side entry remaining technology in the condition of high water volume was conducted. The support method of gob-side entry remaining the individual prop cooperating with the articulated roof beam was proposed, which got a significant effect. The bottom of gob-side entry remaining and the deflection of the two sides were controlled within 1 000 mm, which solved the support of gob-side entry remaining in the condition of great water problem and got a good economic benefit, which provided reference and experience for similar conditions.
