摘要
文章介绍了高河矿E1302综放工作面平推过F_(1n)(H=3.8 m)大断层的回采工艺和顶板管理,对F_(1n)断层进行了认真分析和论证,大胆创新,提出了"水平推进过断层"的技术方案,保证了工作面过断层期间的安全生产,取得了良好的经济效益,为以后工作面回采过大断层提供了一定的经验。
This paper introduces Gaohe E1302 fully-mechanized caving mine horizontal pushing through F_（1n）（ H = 3. 8 m） extraction technology of large fault and roof management,the F_（1n）fault has carried on the earnest analysis,bold innovation,put forward the＂horizontal push through fault＂ ＂technical plan,ensure the safety in production during working face through fault,has obtained the good economic benefit,for the mining face is too large fault provides certain experience.
