中文摘要:地下矿山开采过程中产生的采空区会引起地表变形,不同采矿工艺和采矿方法对地表影响范围及影响程度存在差异。对比研究了多种地表变形预测方法,采用数值模拟的方法对某铜矿的开采过程中建筑物地表进行了分析,得到了开采过程中的建筑物地表的变形规律,并对建筑物的稳定性影响范围及大小进行分析,结合相关规范进行了判别与论证得出,采用数值模型地表布置监测点的方法,可以有效的对需要研究的每个建筑物所在位置进行独立的深入的分析其地表变化情况,同时也可以得到大量相关数据,数值模型上布置监测点的方法对于相似矿山地表建筑物稳定性分析具有一定的借鉴意义。

Analysis of the Influence of Underground Mining in Metal Mines on the Stability of Surface Buildings
Abstract:The goaf produced during the underground mining process will cause surface deformation, different mining processes and mining methods have different effects on the extent and impact of the surface. A comparative study of various surface deformation prediction methods, using numerical simulation method to analyze the ground surface of a copper mine during mining, obtained the deformation law of the building surface during mining, and analyze the scope and size of the stability of buildings, combining relevant specifications for discrimination and demonstration, the method of arranging the monitoring points on the numerical can effectively and independently analyze the surface changes of each building where the research needs to be conducted, at the same time, it can get a lot of relevant data. The method of arranging the monitoring points on the numerical model has certain reference value for the stability analysis of the surface buildings of similar mines.
