| 摘 要： | 随着开采深度的增加，岩爆、瓦斯突出、流变、底板突水等非线性动力学灾害现象日趋增多，严重影响了深部资源的安全高效开采。深部开采工程中产生的岩石力学问题成为目前国内外采矿及岩石力学界研究的焦点。针对深部工程所处的特殊地质力学环境，通过对深部工程岩体非线性力学特点的深入研究，建立了深部的概念体系，指出进入深部的工程岩体所属的力学系统不再是浅部工程围岩所属的线性力学系统，而是非线性力学系统，传统理论、方法与技术已经部分或绝大部分失效。以难度系数及危险指数作为深部工程围岩稳定性控制难易程度的评价指标，能够综合反映深部工程岩体的力学特性与工程特性。

| Abstract: | With the increasing of mining depth, the nonlinear dynamic mechanical phenomena, for instances, the rock blasting, gas outburst, rock rheology, and water outburst, etc., occur with high frequency. The problems of rock mechanics caused by the deep mining engineering are the focuses in the fields of mining engineering and rock mechanics. Based on the studies of the particular geomechanical environments of deep engineering rock mass and its nonlinear mechanical characters, the conception system is put forward, which points out that the mechanical system of deep engineering rock mass is the nonlinear mechanical system, but not the linear mechanical system in shallow, and the classic theory, design method, and technology are almost entirely or partially invalid. By Using different coefficients and hazard indexes as the evaluation indexes to estimate the controlling conditions of surrounding rock masses, it can synthetically reflect the mechanical characters and engineering characters of rock masses in deep engineering. |
