深井開采地表移動變形響應時空關聯(lián)模型研究及應用

深井開采地表移動變形響應時空關聯(lián)模型研究及應用摘要

我國深井開采地表移動變形響應時空關聯(lián)研究成為了當前的熱點問題之一。本文提出了一種新的深井開采地表移動變形響應時空關聯(lián)模型，該模型基于深井開采巖體的動態(tài)變形學理論和地表移動監(jiān)測數(shù)據(jù)，并充分考慮與地下煤層開采工程的關聯(lián)。本文首先從地表監(jiān)測數(shù)據(jù)的采集和處理方法入手，結合神經(jīng)網(wǎng)絡和貝葉斯網(wǎng)絡等分析方法，分析了觀測數(shù)據(jù)的特點，提出了一種對數(shù)據(jù)進行預處理和異常檢測的算法。其次，以深井開采為例，對深井開采中地表的變形機理進行了分析，總結了深井開采地表變形的主要因素，建立了深井開采地表移動變形模型，同時計算和預測了地表形變的程度和分布規(guī)律。最后，以實際深井開采工程為例，應用了本文提出的模型，獲得了可信的預測結果，并驗證了模型的有效性和可靠性。
