  3. 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

    摘要為研究急斜煤層水平分段放頂煤開采過程中基本頂破壞活動對工作面的影響，根據急斜煤層基本頂具有傾斜狹長板的特點，運用彈性薄板理論對基本頂巖層進行了拉應力分析，得出了頂板破斷的判別準則，建立了基本頂初次破斷后形成的「鉸接結構」的力學模型。
