利用老采空区防治矿井水害的工程技术

Filling old shallow goaf by grouting is an effective way to assure the stability of foundation of buildings above the old goaf.

浅部老采空区注浆充填是保证老采空区建筑物地基稳定的有效措施,在确定充填治理范围时,目前大多采用正在开采的地表移动角确定注浆充填范围,这将导致充填范围过大,造成不必要的浪费,为此,基于国内开采沉陷资料,首先建立了正在开采的地表移动角与深厚比的关系,然后在分析老采空区变形机理基础上,提出了残余移动角的思想,根据残余移动与正在开采的地表移动相似性,建立了残余移动角与老采空区开采深度、等效开采厚度之间的关系,给出了老采空区充填注浆范围的确定方法,为老采空区充填治理范围的确定,提供了可靠的理论和方法。

Taking Chenzhuang residential quarter of Pingdingshan Coal Mining Bureau for example, the evaluation method of foundation stability over goaf was systematically studied.
