Borehole radar advanced detection technology of CCTEG Xi'an Research Institute was exhibited at the 2nd China International Mining Equipment and Technology Exhibition. This technology can perform data processing and interpretation along the borehole trajectory, and detection work hidden disaster control geological structures such as in-plane faults, fissure zones, collapse pillars, and goaves to realize the transparency of the geology around near-horizontal boreholes in coal mines, creating a new method for the transparency of coal mine geology.
The borehole radar geological advanced detection technology of CCTEG Xi'an Research Institute is based on the working mode of long boreholes in coal mines. It realizes long-distance and accurate detection of the existing forms of coal seams in front of the tunnel and the hidden disaster-causing geological factors. It can analyze the distance and shape of the reflector and is suitable for the exploration of fault zones, cavities, and weak rock formations around boreholes. This technology uses the drill push method to collect data, which improves the depth and accuracy of borehole geological detection. Its characteristic is that it can transmit signals to the 360-degree space around the borehole and efficiently receive reflected signals. It also uses radar and borehole trajectories. The method of synchronous measurement forms a structural modular design, thereby enabling precise detection of geological structural anomalies within a 15-meter radial range of the borehole, effectively overcoming the "short excavation, short exploration" and "exploration drilling" problems faced by traditional excavation tunnel advance detection. "separation" and other limitations, it realizes the unification of advance detection and rapid excavation in time, space and detection environment, and effectively improves the work efficiency of advance detection. Not only that, the borehole radar geological advance detection technology uses mobile phone collection software, which has the characteristics of simple operation, real-time data, and pictures and texts, which greatly improves the practicality and popularization of the technology.
At present, this technology has been successfully applied in Yulin Mining Area, Huaihe Energy, Pingdingshan Mining Area, and other areas, meeting the needs of long-distance, high-precision, all-round structural detection along the direction of tunnel excavation and the investigation of hidden disaster-causing geological factors and hidden dangers, providing tunnels with Safe and rapid excavation provides the basis for geological support.
