Abstract


With global energy issues become more prominent , coal as one of China 's important energy , its production has also been continuously developing and expanding needs . Underground mining would inevitably lead to surface subsidence , resulting in the damage of environmental resources . Along with the size of the mine construction and coal mining subsidence expanding range , a large area of ??subsidence surface uneven deformation , inevitably on the upper part of the building damage , relying on traditional protection pillar leaving in buildings , building off-site relocation of mining and take measures to reinforce and maintenance measures to achieve coal mining under buildings , not only a waste of resources , relocation is difficult , costly , maintenance and reinforcement of the heavy workload , and will involve a lot of social problems , the building after technical and economic comparison take special protective measures . At home and abroad of the building resistance to deformation has been designed for a large number of studies , this paper based on the results of previous studies , masonry structure buildings of the subsidence the proposed methanol plant and large-scale equipment to improve the resistance to deformation , and the plant has been optimized layout . ( 1) This article discusses the different types of ground movement and deformation of the mining area of building structures and equipment , analyzed and summarized subsidence building (structure ) building was a variety of causes of cracks . (2) focuses on the the subsidence construction (structure ) building materials and large equipment resistance to deformation measures . Resistance to deformation designed to follow the flexible design principles and rigid design principles , measures focuses on the reinforcement and adjustment of the upper structure , foundation treatment , to discuss the idea of the foundation and the basis of coordination . ( 3) Building Pile technical specifications \calculated load affect the depth. By analyzing the simulation results , the siting of the tower equipment optimized layout . (4) places north of mine , five mining area specific geological and mining conditions as the background , use of the subsidence prediction subsystem is expected to surface deformation , deformation contour map generated hierarchically divided subsidence surface deformation , combined with methanol plant process and large resistance to deformation requirements, optimize the layout on the chemical plant .
