顶板运动,roof movement
1)roof movement顶板运动
1.Based on numerical results of impacted roof movement at four stages which have been verified in-situ, the damping effects of roof movement at the impacted stage with three-dimensional distinct element code and chaotic dynamics theory are studied.根据现场验证的冲击性顶板4个阶段运动特征的数值模拟结论,采用三维离散单元法研究冲击阶段顶板运动的阻尼效应,并进行相应的混沌动力学分析。
2.After investigation of the main factors for roof movement, i.利用离散元和有限元数值模拟及力学解析计算，分析了放顶煤采场中上覆岩层运动规律；认为采场上覆岩层运动为分层运动，运动结构为拱－梁结构；拱－梁转换的实现，是以拱顶的失稳升高为条件，在分析了影响顶板运动的主要因素（顶板岩层断裂角、放煤步距、顶板岩层块体尺寸、顶煤厚度）的基础上，认为放煤步距过大（≥２ｍ）会降低放煤率，增大老顶垮落的动压冲击程度。
