摘要
针对厚松散层岩移参数变化规律,利用相似理论推导研究开采沉陷规律的5个相似准数,建立了简化的岩移参数走向、上山、下山的相似准数函数模型。利用Origin软件的统计分析功能,对70多个观测站实测数据进行统计分析,揭示了预计参数与角量参数和相似准数间变化规律。
In order to research rock movement parameters variation of thick loose strata, five similarity criterions of mining subsidence were conducted by similarity theory, then simplified similarity criterion function models of rock movement parameters were conducted, which included that along strike, raise and down.The measured data that collected from seventy observation stations were analyzed with software Origin; the results illustrated that change rule of forecast parameter, angular parameter and similarly criterion.
