【摘要】：大量的國內(nèi)外研究表明,開采沉陷預(yù)計不僅是評價采動損害程度、選擇采動損害控制措施的基礎(chǔ),也是開采設(shè)計優(yōu)化、土地復(fù)墾和地基穩(wěn)定性評價的前提條件之一。從預(yù)計方法的表達(dá)形式、理論基礎(chǔ)、時間過程和特殊條件影響等4個方面分析了開采沉陷預(yù)計理論與方法的類型及適用條件;討論了開采沉陷的主要影響因素、預(yù)計參數(shù)的確定和預(yù)計誤差,強調(diào)了預(yù)計誤差和擬合誤差的區(qū)別。從現(xiàn)有預(yù)計方法存在的不足、時空力學(xué)模型、復(fù)雜地質(zhì)體的節(jié)理界面效應(yīng)、急傾斜煤層開采、深部開采、數(shù)值模擬、地面監(jiān)測數(shù)據(jù)實時獲取、預(yù)計結(jié)果的可靠性與不確定評價等方面,提出了開采沉陷預(yù)計存在的問題和今后的研究方向。
[Abstract]:A large number of studies at home and abroad show that the prediction of mining subsidence is not only the basis for evaluating the degree of mining damage and the selection of mining damage control measures, but also one of the prerequisites for optimization of mining design, land reclamation and evaluation of foundation stability. The types and applicable conditions of the prediction theory and method of mining subsidence are analyzed from four aspects: the expression form, theoretical basis, time process and the influence of special conditions. The main influencing factors of mining subsidence, the determination of prediction parameters and the prediction error are discussed, and the difference between the prediction error and the fitting error is emphasized. From the shortcomings of existing prediction methods, spatio-temporal mechanical models, joint interface effects of complex geological bodies, steep coal seam mining, deep mining, numerical simulation, real-time acquisition of ground monitoring data, In the aspects of reliability and uncertain evaluation of predicted results, the problems and future research directions of mining subsidence prediction are put forward.
