综采工作面掘送探巷过大断层技术研究

高产高效矿井是当今现代化煤矿的发展方向.高产高效矿井必须保证工作面安全、连续、稳定生产.然而,综采工作面通过与倾向近乎一致的断层时,经常发生产量骤降,甚至冒顶、停产的问题,严重制约高产高效矿井建设.为了解决这一难题,杜儿坪矿在68303工作面研究采用沿断层走向掘送探巷过大断层技术,使该矿在安全生产、衔接接替、产量任务、经营管理等方面取得了实效.

Research on Passing through Large Fault Technology of Digging and Exploring the Tunnel in Fully Mechanized Mining Face

High yield and high efficiency mine is development direction of nowadays modern coal mine.High yield and high efficiency mine must ensure work safety,continuous,stable production.However,when the fully mechanized coal mining face passed through the fault with a tendency to almost the same,often occur the problems such as yield drop,even roof fall,stop production and so on,seriously restricted the construction of high production and high efficient mine.In order to solve this problem,in 68303 working face of Du’erping coal mine along the fault strike dug exploration tunnel and passed through the large fault,so that the mine obtains actual effects in safety production,link replacement,production task,operation management and other.
