幼儿园作为幼儿教育实施和运作的基本平台,在现代幼儿教育中发挥着重要作用。 - Theory that the sur - hinge - point is pivotal point provides theoretical basis for the filling to prevent the instability of the basic roof
铰接结构的上铰接点是岩层控制的关键点,这为现场实施充填以防止基本顶失稳的动力作用,提供了理论依据。 - In order to study basic roof ' s destruction movement that affects working face in horizontal section top coal caving in mining steep seams , this paper analyses tension of roof using elastic and thin board theory and concludes criterion of roof destruction based on long and narrow thin board
摘要为研究急斜煤层水平分段放顶煤开采过程中基本顶破坏活动对工作面的影响,根据急斜煤层基本顶具有倾斜狭长板的特点,运用弹性薄板理论对基本顶岩层进行了拉应力分析,得出了顶板破断的判别准则,建立了基本顶初次破断后形成的“铰接结构”的力学模型。 - In order to study the basic roof ' s destruction movement that affects working face in horizontal section top coal caving in mining steep seams , this paper analyses tension of roof using elastic and thin board theory and obtains criterion of roof destruction based on long and narrow thin board
