地下采动岩层移动预测理论分析与研究

Prediction of Underground-induced Strata Movement──Theoretical Analysis and Research

预测岩层移动范围是地下工程设计的前提 ,其预测的可靠性与预测方法有关。对目前用于岩层移动预测的 3类方法进行了分析 ,指出每一类方法的适用条件和存在的问题。针对复杂多变的地下工程问题 ,结合程潮铁矿西区地表移动研究 ,提出了根据工程类比、数值分析与现场监测三者相结合的参数修正与预测技术路线 ,并研究和开发了“地下采动岩层移动预测系统”。

The range of strata movemet is an important basis for underground engineering design. Its prediction's reliability has something to do with rock's parameters and their prediction methods. 3 types of currently-used predicting methods are analyzed and their applicable conditions and existing problems are pointed out. Directing to the complexity and variety of underground mining engineering and consulting the study on surface movement of the westen region of Chengchao Iron Mine, the integrated predicting scheme is put forward which is based on project comparision, numerical analysis and field supervision, and the predicting system of underground mining-induced strata movement is developed.
