摘要
矿区地表沉陷是制约地下采矿工作的一个重要因素,在地下矿体开采过程中,岩体逐步松散冒落充填采空区并向上传递至地表,从而引起地表变形移动,不可避免地对地表构筑物及各种设施造成破坏。以金山店铁矿东区为例,利用离散元软件UDEC模拟了该矿区2#矿体-130 m水平以上矿体开挖以及-270 m放顶工程引起的地表移动变形,探究了二者所引起的地表移动变形规律,为矿山后续工作的开展提供理论依据。
The underground mining work by mining industry company is restricted by the surface subsidence of mining area, which is an important factor. In mining process, looser rock mass gradually fill mined-out area and pass up to surface. Consequently, the structures and facility over the land were damaged. Taken east area in Jinshandian iron mine as an example, the UDEC was used to simulate the surface movement caused by the mining area of -130 m level or above and -270 m ore bodies excavation engineering in 2# ore body. The laws of surface were studied. It provides theories for following work.
