| 摘 要： | 文章通过对煤层采空区的分布、地压作用、山体开裂和近２０多年来的变形等方面的综合分析，得出链子崖危岩体具有南北强拉裂、东西弱拉裂和平面反时针转动的立体开裂变形机制。据此，作者进行了有针对性的计算，为危岩体综合加固体系的建立提供了依据。

| Abstract: | The deforming-cracking mechanisms of strong pulling-apart in south-north direction, weak pulling-apart in east-west direction ,and anticlockwise rotation on the horizontal were been recognized after analysis of distribution of coal mined-out area, geopressure action on the roof, and rock body fracturing and deformation in last twenty yea's in this article. On the above analysis,the authors made a series of calculations and applied them to engineering design for controling the Lianzi Cliff dangerous rock body. |
