摘要
基于铁路沉陷观测站实测资料,求取了多个工作面的概率积分法预计参数,获得了深部开采沉陷规律,并针对深部开采单个工作面属于非充分采动的特点,对下沉系数进行了修正和综合分析,研究成果为矿区今后开采沉陷控制提供了科学依据。
On the basis of the railway subsidence observation data,probability integral method predicting parameters of several working faces were calculated,and the law of deep mining subsidence was obtained. And for the characteristics of incomplete mining of a single working face in deep mining,the subsidence coefficient had been modified and comprehensively analyzed. The research results provided a scientific basis for the future mining subsidence control in mining areas.
