摘要
通过观测枣庄、淮南、开滦、峰峰、大屯、大同等矿区,开展了覆岩破坏特征的研究,得出了煤层覆岩的破坏范围形态,以及冒落带和裂隙带高度的计算公式,准确确定冒落带和裂隙带范围,为煤层开采、顶板管理奠定基础。
Through the observation of a series of mining area such as Zaozhuang, Huainan, Kailuan, Fengfeng, Datun, Datong, carry out characteristic of overburden failure of overlying strata of coal seam, the destruction form, as well as the caving zone and fractured zone height formula, accurate determination of caving zone and fractured zone, lay the foundation for coal mining, roof management and gas drainage.
