综放面顺槽采空区后方顶板受锚固力的作用不能及时垮落，易形成大面积悬顶和瓦斯积聚，严重制约了煤矿的安全高效生产。TMQ400型快速退锚装置可以使回采面两端头锚索快速退锚，减少材料消耗。以国阳二矿为背景，介绍了综放工作面快速退锚装置的工作原理、退锚及放顶工艺，通过现场应用，实现了80906工作面的安全高效生产。
綜放麵順槽採空區後方頂闆受錨固力的作用不能及時垮落，易形成大麵積懸頂和瓦斯積聚，嚴重製約瞭煤礦的安全高效生產。TMQ400型快速退錨裝置可以使迴採麵兩耑頭錨索快速退錨，減少材料消耗。以國暘二礦為揹景，介紹瞭綜放工作麵快速退錨裝置的工作原理、退錨及放頂工藝，通過現場應用，實現瞭80906工作麵的安全高效生產。
종방면순조채공구후방정판수묘고력적작용불능급시과락，역형성대면적현정화와사적취，엄중제약료매광적안전고효생산。TMQ400형쾌속퇴묘장치가이사회채면량단두묘색쾌속퇴묘，감소재료소모。이국양이광위배경，개소료종방공작면쾌속퇴묘장치적공작원리、퇴묘급방정공예，통과현장응용，실현료80906공작면적안전고효생산。
The full-mechanized caving mining face tectonite roof is not caving in time because of the effect of anchoring force,easy to form a large overhang and gas accumulation in upper corner,severely restricted the safe and efficient production.TMQ400 type rapid retreat windlass can achieve anchor rope in two ends of the stoping face re-treat quickly and reduce material consumption.With Guoyang No.2 coal mine as the background,introduced the working principle of rapid retreat windlass ,retreat anchor and caving technology.Through field application,realized safe and efficient production in 80906 working face.
