老鹰山矿区潜伏土洞的形成探讨及处理方法

RESEARCH THE TREATMENT AND FORMATION OF THEPOTENTIAL HOLESIN LAOYINGSHAN COAL-MINE

通过对老鹰山矿区潜伏土洞形成原因及过程探讨,表明潜伏土洞形成是一个渐变过程;初始阶段土洞形成后,并非永无止境地扩展,而是用平衡拱来暂时维持平衡;潜伏土洞自身的稳定与否直接影响地基的稳定性;发展速度与地质条件、水文因素关系密切;并有针对性地提出处理潜伏土洞的几种方法。

I write the text to research the reasons and processes of the potential land-holes in Laoyingshan coal-mine, and to show the formation of potential land-holes are gradual process; after the first potential land-holes were formed, they were not never-ending expansion, but temporarily balanced by the balance bars;Whether the stability of the foundation is influenced by the stability of potential land-holes; the pace of development is closely related to the geological conditions and hydrological factors; Now I want to talk about some methods of dealing with the potential land-holes.
