摘　　要：兴隆庄煤矿10305综放工作面为仰斜开采,回采过程中端面稳定性极易引起片帮冒顶,在回采600m范围内距底板3.0~3.2m发育一厚0~0.8m左右之炭质泥岩夹矸,加大了对顶板的控制难度,回采条件复杂多变,通过采取相应的顶板控制技术,确保了该面的顺利回采。Xinglongzhuang coal mine 10305 fully mechanized caving face in inclined mining, mining process of face stability is extremely easy to cause the roof in mining, the range of 600 m from the bottom of 3 ~ 3.2m were 0 ~ 0.8m thick around the Carbon Mudstone partings, increase the difficulty of control on the roof, the mining conditions are complicated by the roof of the corresponding control technology, to ensure the smooth surface mining.
