钻孔位置是为了了解一定的地质情况而設計的,由于地形的变化及机组安裝时有时存在一定的困难,所以在设計一般鑽孔的平面位置时,允許施工的孔位与原設計的孔位有一定的誤差。这种誤差是由地質方面根据钻孔的任务及地形的复杂程度等条件而規定的,鑽探必须按照地質設計的要求与标准施工,不允 The drilling position is designed to understand the geological conditions. Due to the change of the terrain and sometimes the installation of the unit there are some difficulties. Therefore, when designing the general drilling position, the hole position of the construction is allowed to be matched with the hole of the original design Bit has a certain error. This error is dictated by the geological aspects of the borehole’s mission and the complexity of the terrain, etc. Drilling must be carried out in accordance with the geological design requirements and standards
