一、问题的提出实践表明,露天矿开挖之后,必然会导致上部地面的下沉和变形。对此,有人曾进行过研究和讨论,并给出了某些计算公式,但对地面下沉的计算仍未能较圆满地解决。本文拟在已有的基础上,试对露天开采引起地面下沉及其数值计算问题,提 First, the problem put forward Practice shows that the open pit excavation, will inevitably lead to the upper ground sinking and deformation. In this regard, some people have conducted research and discussion, and given some formulas, but the calculation of the ground subsidence has not been satisfactorily resolved. This article intends to test the ground subsidence caused by open-pit mining and its numerical calculation
