Utilizing Ground-Penetrating Radar (GPR) in Subsurface Applications to Detect and Investigate Buried Marble, Along with the In-Situ Identification of Potential Cracks

This research focused on employing two distinct methods to comprehensively identify potential irregularities, debris, and cracks within marble blocks. The first method centered on directly detecting marble blocks buried at a depth of 0.2 m by utilizing Ground Penetrating Radar (GPR). This approach involved the deployment of GPR devices to emit electromagnetic waves into the ground, capturing their reflections to create a detailed internal structure map of the marble block. The second method involved leveraging simulation software, known as GprMax2D, to analyze the same marble block but at a greater depth of 0.5 m. In this method, sophisticated computer models were generated to simulate how GPR technology would respond when used at this specific depth. The outcomes of this investigation conclusively demonstrated that the combination of GPR technology with appropriate simulation software has the potential to be effectively employed in the marble quarrying industry. Notably, these methodologies enable the differentiation between high-quality, usable marble blocks and those marred by internal fractures or residual debris. This discovery holds substantial promise for the marble industry, as it can contribute to the enhancement of the quality of finished marble products while reducing losses associated with defective blocks.
