综采工作面大角度俯斜开采的实践

Wide-angle Downhill Mining on Fully Mechanized Coal Mining Face

针对综采工作面两端部沿顶板开采,中部从顶板过渡到沿底板开采,形成一个最大走向俯角21°、倾向倾角36°的综采工作面,在开采实践中解决了支架防倒、端面漏顶、运输机倾斜状态下的运行等技术难题。

Both ends on fully mechanized coal mining face should be exploited along the roof; the middle part should be mined along the baseboard which transited from the roof, and formed a fully mechanized coal mining face （maximum depression of 210, inclination of 360）. In the extracting practice, several technological difficulties has been solved, such as anti-inverted support, leaking roof of end face and conveyor operation under heeling condition.
