大采高综采工作面上覆岩层运移规律研究

The Movement Law of Overlying Strata in Working Face Mine

通过理论计算的给出了斜沟矿8号和13号煤层上覆岩层的冒落带及裂缝带的高度及运移规律,并通过3DEC数值模拟软件对上覆岩层的各层下沉量进行监测,发现在煤层开采时155 m测点的位置上覆岩层总下沉量最大约为1.76 m,为斜沟矿巷道的支护提供一定的借鉴。

This paper gives the height and migration law of the caving zone and fracture zone of the overburden of the No.8 and No.13 coal seams in Xiegou mine by theoretical calculation,and monitors the subsidence of each layer of the overburden by 3DEC numerical simulation software.It is found that the overburden is located at the 155 m measuring point when the coal seam is mined.The maximum subsidence of the layer is about 1.76 m,which can be used for reference for the support of the roadway in Xiegou mine.
