The Vector Calculation of the Determination Stratum's Tilt Angle and Azimuth by Three Bore-holes 由三钻孔确定岩层倾向的矢量计算法
On-the-spot investigation was made on the basic parameters of gas drainage in drivage roadway in Huainan Coal Mining Area, and reasonable arrangement range of rib bore-holes and reasonable drainage time were determined. 现场考察了淮南矿区掘进巷道瓦斯排放的基本参数,确定了巷帮钻孔的有效布置范围和合理抽放时间。
According to the space coordinate of three bore-holes, the stratum's surface equation is established by means of space vector analysis, then the tilt angle and azimuth of the stratum around the bore-hole are calculated, and the depth of other bore-holes can be estimated. 该方法是根据三个钻孔到某一岩层点的空间坐标,借助于空间矢量解析法来建立岩层的面方程,从而确定该岩层的倾角和倾向,并预计其它钻孔的深度。
He paper introduces a method with which the stratum's tilt angle and azimuth are determined by three bore-holes. 介绍一种以三个钻孔的测孔元素来确定岩层产状的方法。
Logging data interpretation discovered hydrocarbon reservoirs in some bore-holes where drilling logs showed no hydrocarbon reservoir. 在我国石油勘探史上,有些探井经录井无油气显示,后经测井解释发现了油气层。
Trial Study of Gas Drainage by Roof Bore-holes on Strike under Different Geological Conditions 不同地质条件下顶板走向长钻孔抽放瓦斯技术试验研究
Application of Gas Drainage Techniques in Bore-holes& Roadway along Roof Strike 煤层顶板走向钻孔(巷道)瓦斯抽放技术的应用
The site is divided according to soil layer thickness and Site partition, and grids division is done, several representative bore-holes in each subarea are selected for one-dimensional response analysis, enlargement effect under different intensities is got. 3. 根据土层厚度和场地类别进行场地分区,并进行网格划分。然后在每一场地分区内,选取若干个典型钻孔,进行一维土层非线性地震响应分析,得到了不同强度地震输入下地表的放大效应。
