摘要: 为了深入了解浅埋深厚煤层开采的覆岩运动规律,采用现场实测等手段对阳湾沟煤矿6204工作面覆岩运动规律进行了详细的研究,结果表明:阳湾沟煤矿导水裂隙带高度为97m,为采厚的12.12倍,垮落带高度为22m,为采厚的2.75倍|采空区的中间测点下沉量大于周边的下沉量,中间下沉速度较快,在整体的形式上表达出对称方式|阳湾沟煤矿在较窄工作面地表的启动距为78m,大约为埋深的0.45倍左右,启动距偏大|工作面上方不能形成“竖三带”,而只能形成冒落带和裂隙带的“两带”结构形式。

Abstract: In order to understand overlying strata movement law of shallow-buried deep coal seam, the paper using field measurement to research the overlying strata movement law of Yang Wan Gou coal mine 6204 working face, the results show that: the height of water flowing fractured zone is 97m, 12.12 times of mining thickness, with a height of 22m collapse. 2.75 times of mining thickness; subsidence center of goaf subsidence is greater than the measuring points around the middle, sinking faster, express the symmetry in the overall form; starting at the surface of narrow face Yang Wan Gou distance of 78m coal mine was about 0.45 times the depth of the distance is too large; above the working face can not form a "vertical three zone", but only the formation of caving zone and fractured zone of the "two belts" structure.
