Based on the investingation and some study methods of the stability on the goaf, the paper has the goaf of the first and second tunnels of wu long channel on coal mine railway leased line in da ning of shanxi province as an example, according to the engineering geological invesitigation and maping in the earth ' s surface, also combining the visit on the relate people, firstly has a geological judge on the space extend of the mostly ledges which have been picked ; then adopts the instrument of engineering surveying and checking ( for short sws ) which is relatively advanced inside and outside to test by surface wave the rockmass and solid near the middle line of the tunnel ( total forty meter ), and has a relatively exact judgment on the place that the goaf impossible reveal ; lastly passing the validate by drilling, it make clear that the results which tested by sws is reasonable and believable, based on finding out clearly the space extend of the goaf, the author makes a relatively systemic study on the stability of wall rock around the goaf
因此，查明采空區的具體位置，在此基礎上對場地進行工程適宜性評價，對整個工程建設具有重要的指導意義。本論文在總結前人對地下采空區勘察及有關穩定性研究方法的基礎上，以山西大寧煤礦鐵路專用線五龍溝1 ~ # 、 2 ~ #隧道采空區為研究實例，在詳細的地表工程地質調查和測繪的基礎上，結合通過對采空區有關人員的探訪，首先對主要開采礦層的空間展布進行地質判斷；然後採用國內外較為先進的工程勘探與檢測儀（簡稱「面波儀」 ） ，對1 ~ # 、 2 ~ #隧道中線兩側一定范圍內（共40米）進行了面波測試，對采空區的可能出露部位進行了較為準確的判斷；最後通過鉆探加以驗證，表明面波儀的測試結果是較為合理可信的。 -

By using multi - channel observations of olr, hirs - tb12, erb, vis, ssmr and ssm i on the us satellites, it is analyzed that the global general atmospheric circulation features related to the anomaly of cold vortex over northeast china and it s premonitors are also revealed. it is found that there is an effected chain, which consists of sea ice over northern hemisphere, sea surface temperature in the mid - east equatorial pacific, asia monsoon and local budget of earth radiation in northeast china, on the anomaly of northeast cold vortex. the impacts of each factor in the chain are discussed. the results indicate that the applications of multi - channel satellite observations on research of climate change are of significance
利用美國氣象衛星olr ， hirs - tb12 ， erb ， vis ， ssmr和ssm i多通道的觀測資料，分析了東北冷渦異常年的全球大氣環流特徵及其關鍵地區的先兆特徵對于東北冷渦異常，發現了有一個由北半球的海冰，赤道東太平洋的海溫，亞洲的季風以及東北地區地氣系統輻射收支組成的影響鏈存在。由此討論了影響鏈上的各因子對東北冷渦異常的作用。結果表明多通道衛星觀測資料的綜合應用在氣候變化的研究和預測中有著重要的意義。
