| 摘 要： | 阐述了综放采场宏观应力壳的基本概念,初步探讨了宏观应力壳与关键层在结构上的宏观联系,分析了在综放开采条件下,宏观应力壳和关键层以及基本顶在承担上覆岩层荷载时各自不同的作用,强调了宏观应力壳是导致综放采场矿压规律不同于分层开采的主要原因。

| Abstract: | The basic concept"macroscopic stress shell"of ore drawing & mining stope is explained.Preliminarily,the structural relation between macroscopic stress shell and key layers is discussed;and the different functions of stress shell,key layers and basic roof plate in bearing cap rock load are analyzed.It is emphasized that the macroscopic stress shell mainly causes different geostatic pressure in the cases of ore drawing & mining and layer-wise ore mining. |

| Keywords: | macroscopic stress shell key layer masonry beam |
