、統(tǒng)計預測法、數值模擬法和綜合預測法等幾類。Rockburstpredictionisanimportantissueinthefieldsofminingengineeringandundergroundengineering,whichisrelatedtothesafetyandstabilityoftheproject.Afteryearsofresearchandpractice,researchershaveproposedaseriesofmethodsforpredictingrockbursts.Thesemethodscanberoughlydividedintoseveralcategories,includingempiricalprediction,statisticalprediction,numericalsimulation,andcomprehensiveprediction.經驗預測法主要依賴于工程實踐中的經驗總結,如根據巖石的物理力學性質、地應力狀態(tài)、開挖方式等因素來判斷巖爆的可能性。這種方法簡單易行,但受人為因素影響較大,預測精度往往不夠穩(wěn)定。Theempiricalpredictionmethodmainlyreliesonthesummaryofexperienceinengineeringpractice,suchasjudgingthepossibilityofrockburstbasedonfactorssuchasthephysicalandmechanicalpropertiesofrocks,geostressstate,excavationmethod,etc.Thismethodissimpleandeasytoimplement,butitisgreatlyaffectedbyhumanfactors,andthepredictionaccuracyisoftennotstableenough.統(tǒng)計預測法則是通過收集大量的巖爆實例數據,運用數理統(tǒng)計的方法找出巖爆發(fā)生的規(guī)律和影響因素,從而建立預測模型。這種方法相對客觀,但需要大量的數據支持,且對于不同地質條件下的適用性有待驗證。Thestatisticalpredictionruleistocollectalargeamountofrockburstinstancedata,usemathematicalstatisticsmethodstoidentifythepatternsandinfluencingfactorsofrockburstoccurrence,andestablishapredictionmodel.Thismethodisrelativelyobjective,butrequiresalargeamountofdatasupport,anditsapplicabilitytodifferentgeologicalconditionsneedstobeverified.數值模擬法是通過建立巖石力學模型,模擬巖石在開挖過程中的應力應變行為,從而預測巖爆的發(fā)生。這種方法能夠較為準確地反映巖石內部的應力分布和演化過程,但需要較高的計算能力和專業(yè)知識。Thenumericalsimulationmethodistoestablisharockmechanicsmodeltosimulatethestress-strainbehaviorofrocksduringexcavation,inordertopredicttheoccurrenceofrockbursts.Thismethodcanaccuratelyreflectthestressdistributionandevolutionprocessinsiderocks,butitrequireshighcomputationalpowerandprofessionalknowledge.綜合預測法則是將上述幾種方法結合起來,綜合考慮多種因素,以提高預測的準確性和可靠性。這種方法是目前巖爆預測研究的一個熱點,也是未來巖爆預測方法發(fā)展的一個重要方向。Thecomprehensivepredictionrulecombinestheabovemethodsandconsidersmultiplefactorstoimprovetheaccuracyandreliabilityofpredictions.Thismethodiscurrentlyahottopicinrockburstpredictionresearchandanimportantdirectionforthedevelopmentoffuturerockburstpredictionmethods.各種巖爆預測方法都有其優(yōu)缺點和適用范圍。在實際工程中,應根據具體的地質條件、工程要求和資源條件等因素,選擇適合的預測方法,并結合多種方法進行綜合分析和判斷,以提高巖爆預測的準確性和可靠性。隨著科學技術的不斷進步和巖爆機理的深入研究,相信未來會有更加先進和準確的巖爆預測方法問世。Variousrockburstpredictionmethodshavetheiradvantages,disadvantages,andapplicability.Inpracticalengineering,suitablepredictionmethodsshouldbeselectedbasedonspecificgeologicalconditions,engineeringrequirements,andresourceconditions,andcombinedwithmultiplemethodsforcomprehensiveanalysisandjudgmenttoimprovetheaccuracyandreliabilityofrockburstprediction.Withthecontinuousprogressofscienceandtechnologyandin-depthresearchonrockburstmechanisms,itisbelievedthatmoreadvancedandaccuraterockburstpredictionmethodswillbeavailableinthefuture.四、新型巖爆預測理論模型ANewTheoreticalModelforRockBurstPrediction在深入研究巖爆現象和現有預測方法的基礎上,本文提出了一種新型巖爆預測理論模型。該模型結合了地質力學、巖石力學、彈塑性力學以及等多個學科的理論知識,旨在更準確地預測巖爆的發(fā)生及其強度。Onthebasisofin-depthresearchonrockburstphenomenaandexistingpredictionmethods,thispaperproposesanewtheoreticalmodelforrockburstprediction.Thismodelcombinestheoreticalknowledgefrommultipledisciplinessuchasgeomechanics,rockmechanics,elastoplasticmechanics,etc.,aimingtomoreaccuratelypredicttheoccurrenceandstrengthofrockbursts.新型巖爆預測理論模型主要由三部分構成:應力狀態(tài)分析、巖石物理性質評價和人工智能預測系統(tǒng)。Thenewtheoreticalmodelforrockburstpredictionmainlyconsistsofthreeparts:stressstateanalysis,evaluationofrockphysicalproperties,andartificialintelligencepredictionsystem.應力狀態(tài)分析是預測巖爆的基礎。通過地質勘探和現場監(jiān)測,獲取巖體的應力分布、應力集中程度以及應力路徑等信息。利用彈塑性力學理論,分析巖體的應力狀態(tài),判斷是否存在巖爆的潛在危險性。Stressstateanalysisisthefoundationforpredictingrockbursts.Throughgeologicalexplorationandon-sitemonitoring,obtaininformationonthestressdistribution,stressconcentration,andstresspathoftherockmass.Usingthetheoryofelastic-plasticmechanics,analyzethestressstateofrockmassesanddeterminewhetherthereisapotentialdangerofrockburst.巖石物理性質評價是預測巖爆的關鍵。通過對巖石進行物理性質測試,如強度、彈性模量、泊松比等,了解巖石的力學特性。結合地質環(huán)境和工程條件,評估巖石的物理性質對巖爆的影響,為后續(xù)的預測工作提供重要依據。Theevaluationofrockphysicalpropertiesisthekeytopredictingrockbursts.Byconductingphysicalpropertytestsonrocks,suchasstrength,elasticmodulus,Poisson'sratio,etc.,wecanunderstandthemechanicalpropertiesofrocks.Evaluatetheimpactofrockphysicalpropertiesonrockburstbasedongeologicalenvironmentandengineeringconditions,providingimportantbasisforsubsequentpredictionwork.人工智能預測系統(tǒng)是新型巖爆預測理論模型的核心。該系統(tǒng)采用先進的機器學習算法,如深度學習、神經網絡等,對大量的歷史巖爆數據進行學習和訓練。通過學習巖爆發(fā)生的規(guī)律和特征,建立預測模型,實現對巖爆的準確預測。同時,該系統(tǒng)還可以根據實時監(jiān)測數據,對巖爆的發(fā)展趨勢進行動態(tài)預測和預警。Theartificialintelligencepredictionsystemisthecoreofanewtheoreticalmodelforrockburstprediction.Thesystemadoptsadvancedmachinelearningalgorithmssuchasdeeplearningandneuralnetworkstolearnandtrainalargeamountofhistoricalrockburstdata.Bylearningthelawsandcharacteristicsofrockburstoccurrence,establishapredictionmodeltoachieveaccuratepredictionofrockburst.Atthesametime,thesystemcanalsodynamicallypredictandwarnthedevelopmenttrendofrockburstsbasedonreal-timemonitoringdata.新型巖爆預測理論模型的優(yōu)勢在于其綜合性和實時性。通
