| 摘 要： | 从分析开采深度的增加导致一系列工程灾害如岩爆、煤与瓦斯突出、顶板垮落、底板突水等日益严重的特点入手，阐述了国内外关于深部、浅部差异的量化界线。进一步针对煤炭科学开采对资源储量和开采技术发展水平的要求，从工作面环境温度、巷道变形控制以及采动岩体能量聚集灾变等方面，论述了极限开采深度的概念，给出了极限深度范围。

| Abstract: | Based on characteristics of a series of engineering disasters such as rock burst,coal and gas outburst,roof weighting,water outburst with increasing depth,a quantitative difference between shallow and deep depth was discussed.Furthermore,based on demand on reserves capacity for sustainable mining and technological development,the concept and limit of critical mining depth were also proposed within the framework of the air temperature of mining face,control of tunnel deformation and mining-induced strain energy accumulation of surrounding rocks. |

| Keywords: | deep mining critical mining depth rock temperature tunnel deformation |
