A PRELIMINARY RESEARCH ON THESURFACE DEFORMATION OF FUSHUNPETROLEUM FACTORY NO. 1 AREA

The main cause for the surface deformation of Fushun Petroleum Factory No. 1 area is the surface bench mining in the western pit of the surface mine. The mining led to slope failure, deformation, and surface subsidence in the factorys southern edge.Meanwhile, this activates other factors and accelerated the development of the ground fissure and deformation.
