摘要
露天开挖将引起周围岩体的变形,随着采深和坡角的增大,其影响范围和影响程度都将增大 在我国有许多老矿区周边是密集城市群,开挖引起的变形对周边各种建筑设施和工厂的安全产生严重的影响 本文主要研究和探讨露天开采对地面建筑设施的影响特点,并就变形可能产生破坏程度进行分析,从而给出一般变形区、危险区和破坏区的划分原则和划分方法。
Deformation for surrounding rock mass is produced by open pit mining.The scope and the degree are increased as the depth and dip angle of open pit mine increase. Due to concentrat ed city's building around it in many mine areas, safety of surrounding factory and all kinds of building facilities are seriously influenced by mining deformation.So, this paper mainly study and probe behavior for all kinds of facilities influenced by open pit mining. Then, the degree of de struction is analyzed.Therefore, general deformed area, dangerous deformed area and destruetion area is given . Scientific basis is provided for safe measure.
