摘要
通过对条带开采宽度与地表移动变形关系的系统分析,指出了二者之间的最 优平衡关系,特别是通过实例分析了具有关键层岩层的情况下提高煤炭回来率的有效方法。
Through systematical analysis over surface subsidence deformation relation caused by various mining face lengths, the paper indicates the best balance relation between the face length and its mining depth. Especially, through practical example analysis over the roof formed of competitive strata, it provides the most effective method to raise coal recovery rate.
