综放面快速退锚装置及其应用

摘要

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.%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。
