摘要
宽条带充填全柱开采借助宽条带开采理念,采用冒落区充填方法,利用全柱开采优势,将地表移动变形过程分解为两个阶段,通过对不同阶段变形值的控制,达到减小采动影响、保护地面的目的。阐述了宽条带充填全柱开采的技术原理,分析了宽条带开采和冒落区充填在宽条带充填全柱开采中的作用,并示例对该方法地表移动变形特征进行了研究。
Full-pillar mining with wide strip filling adopts the idea of wide strip mining and the method of caving zone filling,and uses the strengths of the full-pillar mining to divide the process of the surface movement ＆amp; deformation into 2 stages,and through controlling the de-formation value in different stages,so as to reduce the mining influence and protect the surface. This paper elaborates the technical principle of full-pillar mining with wide strip filling,and ana-lyses the effect of wide strip mining and caving zone filling in this technology,and researches the features of surface movement and deformation resulted from this technology with demonstrations.
