The Development Law Of Geological Disasters In The North Slope Of Fushun West Open Pit And Its Environmental Impact

Taking the geological hazards assessment of fushun power generation Co., Ltd as theengineering background, study systematic on the project.This paper introduce the regionalgeological environment and the hydrogeological characteristics of the study area, geologicalhazards assessment was done on the basis of the current situation, and the grey theory is used topredict and analysis the foundation deformation of fushun power generation Co., Ltd.Finally,use the method of variational yen numerical analysis in the study area, in order to study thedeformation in the process of stress change and development trend.Under this background, thispaper mainly in the following several aspects:(1) Data collection and field investigation, according to the project needs, the geologicalenvironment data and hydrogeological characteristics in the study area are collected, and use themethod of geotechnical engineering investigation to investigate the field.（2) Produce an initial assessment according to the collected data and survey data, givea preliminary evaluation about the geological hazards present situation of the study area.(3) Arrangement settlement observation point to get settlement development trend In thestudy area.Using grey theory to analyze it.Through the analysis, in2010and2010, the factorybuilding foundation deformation will exceed maximum specification requirements.In theanalysis of grey theory only consider the influence of foundation settlement of the factorybuilding, but with open pit mining process, changes happen of fushun power plant factory withthe horizontal displacement.Horizontal displacement change is the cause of the factory buildingdamage.(4) By using numerical simulation software, the yen (elm) method is adopted to thenumerical simulation of the study area, calculation is on the basis of the theoretical calculation ofdeformation on the status quo analysis, and compared the calculated results and monitoring data,to verify the correctness of the calculation model and parameter selection, calculate the effecton the stability of the power generation co., Ltd. plant by the future mining of fushun west openpit mine(5) Through the numerical simulation analysis, the change of horizontal displacement andvertical displacement of the study area is concluded from2002to2002, the plastic zone iscalculated to analyze the causes of the geological hazards.(6) Use the numerical simulation software to analysis the slope stability, respectively,regardless and consider the groundwater conditions.
