1)pressure arch压力拱
1.It has shown that the pressure arch,rather than the beam or plate,can be formed under the shallow-buried and very loose roof.浅埋深极松软顶板难以形成“梁”或“板”结构,随着开采,将形成“压力拱”结构;当采场推进到一定距离时,拱结构失稳破坏,产生初次来压;当拱顶高度接近地表时,压力拱主结构内岩体失稳破坏,引起工作面更剧烈来压,同时,拱外次结构内岩体随之破坏,引起地表下沉;压力拱结构周期性失稳并前移,引起工作面周期来压。
2.The pressure arch was defined, and its boundary was determined based on stress analysis.对压力拱拱体进行定义,通过应力分析确定拱体的边界,并用数值分析方法对拱进行分析。
