摘要
A矿表土厚度较大,工作面需要在厚松散层下开采,通过数值模拟软件对厚松散层下条带式开采引起的围岩变形规律进行研究,结果显示,高度在50 m以上的松散层受采场采动的影响较小,工作面开采后地表发生向中心位置的倾斜,同时地表下沉并未表现出波浪形的特征,以期通过研究促进相关工作的开展。
The surface thickness of A Mine is large, and the working face needs to be mined under the thick unconsolidated layer. The deformation law of surrounding rock caused by strip mining under thick unconsolidated layer was studied by numerical simulation software in this paper. The results showed that the loose layer above 50 m is less affected by the stope mining, and the surface is inclined to the center after mining the working face, while the surface subsidence has not shown the wave shape characteristic. The study aimed to promote related work through research.
