The law of ground pressure activities in level 448 is studied and three steps based on different theories are involved. The event density contour plot is used for establishing the risk region. Observation period, prediction period and danger period are set up based on earthquake parameter time curves. The statistics of b value are made for checking the result. After that, the particular middle risk assessment of that area is performed by using the statistics and magnitude theory. Then the film clip stopped is confirmed with emphasis on the area of risk assessment and prediction area. Theoretical analysis and practical results show that the mine ground pressure activity is not only related to the time but also closely to underground mining activities. And the underground mining activity is an important risk resource in the underground environment. The seismic event concentrated area corresponds to the underground working position. The peak activity of seismic event is in accordance with stopping and developing machine-team in spatial and temporal domains. Those three periods are set up when determined based on earthquake parameter time curves. If so, less persons and property losses can be achieved. Combined with the current monitoring results and work, when the instability signal appears, the system can inform the miners, providing safeguard for mine safety production., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=wy14DpSiVJNO5C6oKR/cLg==, pdfFileSize=3260886, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
