A Review On Research Of Reflected In-Seam Wave Detection Technology In Coal Mine, Wang Ji, Ye Hongxing, Zhang Guangzhong, Li Gang, Wu Guoqing, Niu Huan, Yang Yanjun, Guan Qi
Coal Geology & Exploration
Reflected in-seam wave can be used in one roadway to detect the abnormal geological structures such as faults in some area on both sides of the roadway or in front of tunneling. In this paper, the data and processing method of the reflected in-seam wave were compared based on the 2 different detection areas on side of the roadway and in front of tunneling. In particular, the technical principles, applicable conditions and research progress of three imaging methods of reflected in-seam wave were analyzed and sorted out, including the stack imaging, migration imaging and advance imaging of tunneling face. Besides, …

Coal Geology & Exploration
Transparency of hidden geological factors is critical to intelligent and precise coal mining and therefore the prevention and control of major accidents in coal mine. The significant electrical property change can be resulted from several factors, such as the structure of coal and rock mass, the fluid occurrence, etc., providing a basis of physical property for mine electrical prospecting. For more than 30 years, mine electrical prospecting has played a key role to water prevention and control of coal mine in China. Definitely, many symbolized results on theory, technique and application of mine electrical prospecting have been produced through several …

Research Progress And Thinking On Integrated Tunneling And Detection Technology Of Rock Roadway With Tbm, Yuan Liang, Zhang Pingsong
Coal Geology & Exploration
The construction of Full Face Tunnel Boring Machine (TBM) in coal mines is crucial for achieving efficient and modern high-intensity development and mining operations. However, TBM has poor adaptability to adverse geological conditions, such as fracture zones, faults, soft rock layers, and water-rich areas, which can cause problems such as collapses, equipment sticking, and water gushing, hindering their development. To fully utilize the rapid tunneling efficiency of TBM, integrated design between advanced detection instruments and TBM must be performed. The key technology is the breakthrough in detection-while-tunneling. This paper reviews recent advancements in the integrated tunneling and detection technology of …
