Informationized rock core storage method

Abstract

The invention belongs to the field of geological engineering exploration and is aimed at solving a problem that a conventional rock core storage method is not convenient for geological works to implement. The invention provides an informationized rock core storage method which comprises the following steps: collected rock cores are placed in a rock core case in such a way that one side, having annotated information, of each rock core is placed upward; a target is arranged on an edge of the rock core case, the target is used for splicing three dimension laser scanning data, a three dimension laser scanner is erected for subjecting the rock cores to three dimension laser scanning, three dimension point cloud data of the rock cores is obtained and processed, rock core three dimension entity models carrying geometrical information are built, and the rock core three dimension entity models and rock core cataloging data are stored in a rock core database, and a virtual rock core warehouse is built. The informationized rock core storage method is suitable for informationized storage of drilling rock cores.

Description

technical field [0001] The invention belongs to the field of geological engineering exploration, in particular to a rock core information storage method. Background technique [0002] Geological drilling is an essential link in engineering surveys, and it is also an important technical means for geologists to obtain information on underground geological bodies. Geological workers can find out the lithology, degree of fragmentation, and development of structural planes of underground geological bodies through the cores taken out by drilling. Important geological factors such as the situation, rock quality index RQD, overburden depth, and material composition. [0003] At present, geologists mainly rely on on-site geological records, panoramic images of drilling holes and digital photos of cores to obtain core data, while the storage of cores is mainly done by building core warehouses near the project site to store cores. Preserve portable data such as geological catalog data...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantages of the current core storage methods are as follows: ①The cores are generally stacked in the core warehouse near the engineering survey site, which is generally far away from the work place of the geologists. It is extremely inconvenient to go to the core warehouse, which is time-consuming, laborious, and increases the workload. ②When the core is stacked in the warehouse, it is inevitable that the drilled core will be damaged or lost due to weathering and human factors. ③The core Digital photos are easily distorted by the shooting angle, and do not have the functions of size measurement and editing, so they can only be used as a reference for qualitative research by geologists; ④The panoramic image of the borehole will not be clear because the borehole wall is not cleaned cleanly image, and it is easy to be distorted during image acquisition and post-image processing
