Abstract : considering the stochastic characteristic of main hydrogeologic parameters in yuanbaoshan open coal pit, a groundwater stochastic management model for optimal drainage borehole design is established. the result of the modeling shows the effect of stochastic characteristics of hydrogeologic parameters on the result of management modeling. it was found that the higher the parameters uncertainty and the management reliability level, the worse the management result
文摘:從影響元寶山露天礦地下水疏乾的主要水文地質參數隨機性特徵分析入手，建立並求解了元寶山露天礦疏干工程優化設計的隨機地下水管理模型，揭示了水文地質參數隨機性對管理模型結果的影響，認為參數的隨機性越大，管理結果越壞；置信水平越高，管理結果越壞，且滲透系數和邊界條件對管理結果影響最大。 -
By link to the opengl api, the plane image can simulate solid borehole status, and it gets intuitionist effect
通過對三維圖形介面庫opengl的操作，將平面圖像模擬成實際的井壁圖形，獲得直觀的效果。 -
In addition, the un qualified injected water will cause the gathering and transporting systems and borehole to be corroded and will form scale in them, which will greatly reduce the waterflood effect
此外，不合格的注入水還會引起集輸系統和井筒的腐蝕與結垢，從而大大降低注水效果。 -
Breast wall effect of double - pipe protecting borehole wall blasting and its functional mechanism
光面護壁爆破的護壁效果及作用機理探討 -
When the vertical formation lies outside of the borehole, the effect of the borehole on the acoustic field decreases with the increase of the distance between the formation and the axis of the borehole ; when the source locates on the interface, with the increase of the azimuth of the dipping interface, the transmitted energy of the horizontal component gradually increases, but that of the vertical component decreases
當井外存在徑向分層時，隨著地層界面遠離井軸，對井內聲場的影響減小。 2 、當聲源位於地層界面以上時，隨著地層傾角的增大，水平分量透過地層界面的聲能量是逐漸增大的；垂直分量的透射聲能量卻是減小的。
