一、概述地下采煤后,地表将产生移动与变形。地表的变形可以分为连续变形和非连续变形两种。波兰目前对地表连续变形的研究比较成熟,预计也比较准确,为减小其对建筑物的有害影响而采取采矿措施和建筑措施的经验也比较丰富。
First, an overview of underground mining, the surface will have to move and deformation. Surface deformation can be divided into two kinds of continuous deformation and non-continuous deformation. Poland is currently more mature in surface deformation studies and is also expected to be more accurate. Experience in adopting mining and building measures to reduce its harmful effects on buildings is also abundant.
