Ground Collapse In The Goaf Area Of Jianchangying Coal Mine And Associated Fissure Research

In this paper,the authors selected the research work on the crack associated with land collapse in the area around the area of the good seed farm in zongshan district of chifeng city.Through systematic field research and comprehensive data analysis,the authors carried out Geological hazard investigation,ground collapse and the development trend prediction of associated cracks,and found out the causes of house cracking in residential areas.The underground coal mining of Jianchang Camp coal mine in Yuanbaoshan District of Chifeng City caused the ground collapse of some arable land in Liangzhu Farm in Songshan District.After coordination with the land department,Jianchang Camp Coal Mine in Yuanbaoshan District signed the "Land Management Compensation Agreement" to reach an agreement.However,in recent years,the area of ground collapse in the land area of the good seed farm has continued to expand,especially the cracks in some residents 'houses.The main working methods used in this study include the collection of meteorological,hydrological,topographic,geomorphological,regional Geological,tectonic,seismic and mining-related data related to the goaf area;Surface topography mapping,disaster investigation,Geological disaster investigation,underground survey,Geophysical exploration,drilling and Geophysical logging in the research area.
