基于空间智体模型的岩体稳定性分析方法

采动岩体稳定性是解决矿山安全问题的关键所在,但是,由于岩体赋存于复杂的地质环境中,变形破坏特征是地质构造、地下水、采矿方法及环境等诸多不确定性因素共同作用的结果,表现为复杂的非线性动力学特性,故采用单一方法难以表征这种复杂系统特性,需要探求一种新的方法。在现有分析方法分析和总结的基础上,研究开采影响范围内的岩体在外界采矿工程环境变化时表现出的自适应系统行为,建立了基于空间智体的岩体稳定性分析模型,通过采动空间智体的内部属性特征、学习机制和外在行为涌现表征岩体的稳定状态及变形破坏规律,最后进行了实例验证。

A METHOD OF ROCK MASS STABILITY ANALYSIS BASED ON SPATIAL AGENT

The stability of rock mass is a key issue in ensuring the safety of mine. Because the rock masses are situated in a complex geological environment with complicated components and structures,hydrogeological conditions,mining process etc.,its deformation presents the behaviors of complicated nonlinear and dynamic characteristics. Therefore,these complex behaviors of the rock mass should be described by the method of spatial agent model based on knowledge fusion technology. It could be used to analyze the stability of rock mass,and to study the adaptive behaviors of a complex system when external environment of the rock mass changes. The stability of rock mass is described in detail by the structure and property,the mechanism of self-study,and the integrated behaviors of the spatial agent. Finally,it is verified by the related theory and case study of a coal mine.
