| 摘 要： | 建立了判别覆岩中关键层位置的实用方法，并编制了相应的计算机软件ＫＳＰＢ。首次 相邻两层硬岩同步破断的理论判别式，并就相邻两层破断顺序的影响因素进行分析，结果表明，两硬岩层厚度、间距以及上层硬岩所承受的载荷大小是影响相邻层硬岩民支破断顺序的主要因素。

| Abstract: | A practical method to distinguish key strata in overburden was put forward, and a computer program KSPB for distinguishing key strata has been drawn up. A theoretical formula was given to decide whether two adjacent hard strata fracture synchronously. The factors influencing the fracturing order of two adjacent hard strata were also discussed. The results show that the thickness of two hard strata, the distance between them and the load on the upper hard stratum are the main influencing factors. |
