为研究深井大采高工作面顶板结构特征及运动规律,以东滩煤矿14316工作面为研究对象,采用理论计算、数值模拟和现场实测的方法对其进行研究。结论表明:建立的大采高顶板结构力学模型与实际基本相符,通过理论计算所得出的数据与现场实测基本一致,能够体现出该工作面顶板的运动规律。
In order to study roof structure feature and movement rule of deep mining face, 14316 working face of Dongtan Coal Mine was selected as the research object, and the theoretical calculation, numerical simulation and field measurement were used to study it. The conclusion shows that the established mechanics model of roof mining with big mining height basically accords with the reality, and the data calculated by theoretical calculation are basically consistent with the field measurement, which can reflect the law of roof movement of the working face.
