【摘要】 采用影响函数法对地下开采引起的上部岩体移动变形问题建立了数学模型,实践证明该数学计算模型可应用于计算地下开采引起的地表变形,并对河南某矿地下开采引起的上部地表水利工程设施安全性的影响进行了分析,分析表明,该地表变形量会使地表建筑水利设施的地基产生裂缝、变形及不均匀沉降,直接影响水利设施的质量和安全运营。更多还原

【Abstract】 The paper establishes mathematical model of upper rock deformation and displacement owing to underground mining by applying influence function method.Practice proves that: the mathematical model can be used to calculate surface deformation owning to underground mining.It analyzes the impact of upper hydrological engineering equipment security owing to underground mining in the mine of Henan province.The analysis result shows that: the surface deformation will lead to foundation cracking,deformation and uneven subsidence of surface building hydrological equipment,which directly influences the hydrological equipment quality and security operation.更多还原
