基于采动"上行裂隙"和"下行裂隙"的条带充填隔水岩组稳定性研究,对条带充填开采"边界煤柱-充填条带-隔水岩组"力学系统稳定性进行分析,根据力学模型计算隔水岩组的受力情况以及充填条带的受压情况,并在此基础上推导出了采动"上行裂隙"和"下行裂隙"的计算公式,可为确定合理充填参数提供科学基础。
Based on the study on stability of water resisting groups, this paper analysed the stability of the mechanical model of "boundary pillar filling strip water resisting groups", calculated the stress condition of water resisting groups and press condition of the filled strip using the mechanical model, and established the formulas for " upward crack" and "downward crack" height, to provide foundation for filling parameter selection.
