摘要
利用数值模拟模型对薄基岩条带开采时所留设的煤柱进行研究,深入分析了不同煤柱尺寸对地表移动变形及地表建筑物的影响,揭示了地表各变形参数与留设煤柱宽度的关系,以及影响地表移动变形的主要因素和对地表建筑物造成的影响,为工程实践提供了理论依据。
In this paper,the parameters of reserved coal pillars for strip extraction below thin bedrocks were studied systematically, and the effects of different coal pillar width on ground movement deformation and building were deeply analyzed numerically. The interrelationship of ground movement parameters and reserved coal pillar width was revealed. The principal influencing factors on ground movement deformation and building were evaluated. The study provides a theoretical basis for engineering practice.
