物探综合解释技术在煤田采空复杂区的应用 Title:ApplicationofIntegratedGeophysicalExplorationTechniquesintheComplexOverburdenAreasofCoalMines Introduction: Theminingofcoaldepositsoftenleadstotheformationofcomplexoverburdenareas,whichposesignificantchallengesforsafeandefficientminingoperations.Theapplicationofintegratedgeophysicalexplorationtechniqueshasemergedasapromisingsolutionforcharacterizingandmanagingthesecomplexoverburdenareasincoalmines.Thispaperprovidesanoverviewoftheprinciplesandmethodologiesofintegratedgeophysicalexplorationtechniquesanddiscussestheirapplicationsinthecoalminingindustry. PrinciplesofIntegratedGeophysicalExplorationTechniques: Integratedgeophysicalexplorationtechniquesinvolvethecombineduseofmultiplegeophysicalmethodstoobtainacomprehensiveunderstandingofsubsurfaceconditions.Thesetechniquesrelyontheprinciplesofphysicstomeasureandanalyzevariationsinphysicalproperties,suchaselectricalconductivity,magneticsusceptibility,andacousticimpedance,inordertoinferthegeologicalstructuresandpropertiesofthesubsurface.Themaingeophysicalmethodsusedinintegratedexplorationincludeelectricalresistivitytomography(ERT),seismicreflection,ground-penetratingradar(GPR),andmagneticandgravitysurveys. ApplicationsintheComplexOverburdenAreasofCoalMines: 1.SubsurfaceImagingandMapping: Integratedgeophysicalexplorationtechniquesareusedtoimageandmapthecomplexoverburdenareasincoalmines.Forexample,ERTcandelineatethedistributionandextentofgeologicalformations,includingfaults,fractures,andwater-bearingzones.Seismicreflectioniseffectiveincharacterizingthestratigraphyandidentifyinglayerdiscontinuities.GPRprovideshigh-resolutionimagesofshallowgeologicfeatures,suchasmineworkings,voids,andareasofcollapse. 2.PredictionofGroundSubsidence: Oneofthemajorconcernsinminingoperationsisgroundsubsidence,whichcanleadtosurfacedeformationsandposearisktoinfrastructureandtheenvironment.Integratedgeophysicalexplorationtechniquescanhelppredictandmonitorgroundsubsidencebyidentifyingareaspronetosubsidence.BycombiningERT,GPR,a
