    Ground penetrating radar (GPR) has been investigated by the U.S. Bureau of Mines Pittsburgh Research Center for its potential to determine roof hazards in underground mines. GPR surveys were conducted at four field sites with accompanying ground truth to determine the value of GPR for roof hazard detection. MSHA and the mining industry have worked together to develop potentially life-saving technology that can stop machine motion and/or send a warning signal to the machine operator when it detects a person or object in the machine’s path. Mine operators are increasingly installing these proximity detection systems on mining equipment in surface and underground mines to prevent.

    Ground penetrating radar technique to locate coal mining related features: case studies in Texas. Master's thesis, Texas A&M University. Texas A&M University. Available electronically from http: / / / /   This paper reports on a novel application of ground penetrating radar to a longwall steering problem in the coal mining industry. The main goal of the work was to determine whether a radar-based system could be used to detect coal-rock interfaces in order to establish a suitable mining horizon within the coal seam.

    Ground Penetrating Radar (GPR) has been in use in Saskatchewan potash mines for nearly 40 years. GPR is an excellent rock imaging tool, and it works particularly well in salt due to the low dielectric properties. The vast and remarkably flat potash deposits in Saskatchewan are occasionally disrupted by geologically anomalies. CSES’s VISOR ground-penetrating radar is designed for buried mine and similar explosives detection using ultra-wideband ground-penetrating radar arrays and automatic target recognition.

Although many geophysical techniques have been used to detect the disaster geological anomalous body in the Huaibei coal mine company, there are still many mining disasters happening.

The main reason is that the coal seam is rich of water in Huaibei coal areas. If the ground water connects with tunnels, it will cause the flood to collapse the coal seam.

Specific Hazards in Underground Mines. Accidents are always a combination of hazards and causes. Making the issue more comprehensible is the only reason for presenting the hazards listed below. The collapse and flood of underground workings may be a.

Compared with the ground detection equipment, the GPR system development is more difficult. Therefore, it is of great significance to develop a novel GPR system for large-depth disaster detection in mine to improve the ability of the ultra-large-depth geological structure detection and guarantee safety mining in coal mine (Cheng et al., ).

Mining induces major shifts in pre-existing ground stresses, and because the stress redistribution and the rock mass response to it are highly interrelated, a successful geotechnical program for underground coal mining requires both adequate characterization of the materials present and identification of changing conditions and hazards as.

Coal mine hazard detection using in-seam ground-penetrating-radar transillumination. Pittsburgh, Pa.: U.S. Dept. of the Interior, Bureau of Mines, (DLC) This paper describes an algorithm for land mine detection using sensor data generated by a ground-penetrating radar (GPR) system that uses edge histogram descriptors for feature extraction and a possibilistic K -nearest neighbors (K-NNs) rule for confidence assignment.

The algorithm demonstrated the best performance among several high-performance algorithms in extensive testing on a large real. During the process of the mine production, many geological factors exist in the coal seam and bring influence on the safety, such as the fault structure, fracture zone, collapse column, and so on.

It is the main performance to reduce the digging efficiency and to affect digging safety during the production of roadway excavation and face mining. According to the difference of the dielectric. Finally, as an example, the characteristics of ground penetrating radar images are analyzed based on the detection results of No water proof gate of Nanye coal mine.

It is well known that the mine water is one of the main hazards in the coal mining. Besides, the relative permittivity of the coal seam is and the relative permittivity of water is Moreover, the velocity of the electromagnetic wave in the coal mine is three times of that in the collapse column containing water.

The Bureau of Mines recently completed peliminary studies to demonstrate the feasibility of using Ground-Penetrating Radar (GPR) for in-seam hazard detection. Investigations included air. The use of ground penetrating radar (GPR) for detecting the presence of near-surface interfaces is a scenario of special interest to the underground coal mining industry.

The problem is difficult to solve in practice because the radar echo from the near-surface interface is often dominated by unwanted components such as antenna crosstalk and ringing, ground-bounce effects, clutter, and.

In this chapter, two of the major challenges in the application of ground‐penetrating radar in humanitarian demining operations are addressed: (i) development and testing of affordable and practical ground penetrating radar (GPR)‐based systems, which can be used off‐ground and (ii) development of robust signal processing techniques for landmines detection and identification.

Using Ground Penetrating Radar for In-Seam Crack Detection in Potash. Chris Kelly 1, Dean Gerhardt 2 and John Unrau 2. 1 Mosaic Potash, Ground Penetrating Radar (GPR) is the technology having the highest potential for success as a detection system. Crack/Clay seam detection at the Colonsay mine. GPR (ground penetrating radar) is an efficient technology that has been used considerably in subsurface exploration.

The modern tools based on the technology are remarkably efficient too. These tools can gather, analyse, assess and process huge chunks of data, allowing the personnel to gain valuable decisions. Benefits of using GPR in Mining.Coal mining - Coal mining - Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining.

Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many .
