基于Rayleigh法的开采沉陷相似准数研究

摘要

针对岩移参数的相似准数问题,基于π定理,以扩充因次M、Lx、Ly、Lz、T代替传统M-L-T因次,利用Rayleigh法推导开采沉陷的相似准数,建立了统一的预计参数与角量参数的走向、上山、下山方向的相似准数函数模型,为矿区岩移参数计算及相似实验分析提供了依据.%It discusses the key problems with similarity criterions of rock movement parameter. Bing based on π theory, as well as extending dimension M、Lx、Ly、Lz、T instead of traditional dimension M-L-T,it deduces similarity criterions of mining subsidence by Rayleigh method,and establishes trend、up、down function models with similarity criterions for prediction param-eter and angular parameter. These models provide basis for calculation of rock movement parameter and analysis of similarity experiment.
