摘要
本文在建立切合实际的模型基础上,通过数学力学分析,阐明了顶板来压前夕可能引起的“反弹”的本质及其产生的力学机理,并分析了影响反弹的主要因素,及其应用在现场来预测顶板运动的意义。
This paper presents the nature of recoil occured just before roof weighting and the mechanism of recoil occurrence on the basis of struduring the practical model through mathematical mechanical analysis, and analyzes the main factores that influence the recoil of roof and the significance of its application in the prediction of roof weighting in situ
