摘要
将采场顶、底板岩层和媒体视为软岩,具有流变性能,引用Maxwell流变模型建立支承压力计算公式,并讨论了支承压力的分布特征及其在采场前方煤体上的分布规律。
Considering the adjoining rock and coal as soft rock with rheological properties,this paper presents a formula for analysis of the abutment pressure according to Maxwell rheological model.Also it discusses the abutment pressure distribution characteristics and the distribution rule of the abutment pressure on the body of coal in front of coalface.
