Purpose

The results showed that the use of a magnetic marker could relatively accurately reflect the fracture pattern inside the rock-like material (RLM).

Design/methodology/approach

This study investigated the internal structure and fracture pattern of a fractured RLM. Magnetized iron oxide powder, which was used as a magnetic marker, was mixed with water and glue to form a magnetic slurry, which was subsequently injected into a fractured RLM. After the magnetic slurry completely filled the cracks inside the RLM and became cemented, the distribution and magnitude of the magnetic field inside the RLM were determined using a three-dimensional (3D) magnetic field imaging system.

Findings

A model for determining the magnetic field strength was developed using MATLAB.

Originality/value

This model of 3D magnetic will further be used as a finite element tool to simulate and image cracks inside the rock.

目的

结果表明,使用磁标记可以相对准确地反映类岩石材料(RLM)内部的断裂模式。

设计/方法/方法

本研究调查了断裂的 RLM 的内部结构和断裂模式。用作磁性标记物的磁化氧化铁粉末与水和胶水混合形成磁性浆料,随后将其注入破裂的 RLM。在磁浆完全填充 RLM 内部的裂缝并胶结后,使用三维 (3D) 磁场成像系统确定 RLM 内部磁场的分布和大小。

发现

使用 MATLAB 开发了用于确定磁场强度的模型。

原创性/价值

该 3D 磁性模型将进一步用作有限元工具来模拟和成像岩石内部的裂缝。
