Embodiment Construction
[0022] The following structural drawings and implementation examples further illustrate the method for restoring the orientation of a drilled rock mass provided by the present invention.
[0023] A drilling core orientation recovery method, such as figure 1 shown, including the following steps:
[0024] (1) Core baseline delineation: if figure 2 As shown, the core 1 is connected in order from top to bottom in the direction close to the surface; the baseline 2 is delineated in the complete splicing section of each core, and the depth mark 3 is marked; when the baseline 2 is delineated, it should be ensured that The cores within the same baseline range are seamlessly spliced to ensure that the relative orientations of each structural plane and the baseline are accurate. This baseline ends and is flagged for cases where the core cannot be spliced due to chipping or breakage. A new baseline is marked on the next complete segment of the core. When delineating the baseline ...
