Topic Information

Dear Colleagues,

Rockburst refers to the dynamic failure of rock mass, involving a sudden release of strain energy which causes violent material ejections to the mine opening. Rockburst is one of the most formidable mining hazards found in underground mines, posing significant threats to personnel, equipment, and infrastructure. In recent years, with the continuous increase in mining depth, underground mines have encountered high in situ stress and challenging environments in the deep rock mass, resulting in frequent rockbursts in most mining countries. To address this challenge, intensive analytical analyses and laboratory tests have been conducted to investigate the occurrence mechanism of rockbursts. Furthermore, to achieve effective burst hazard control and prevention, several techniques such as microseismic, stress, and acoustic emission (AE) monitoring have been applied to burst-prone mines. Many methods have been developed, whether for assessing rock stability around excavations or identifying precursors before burst damage. Therefore, to gain a deeper understanding of the latest research progress on rockbursts in underground mines, this Topic invites original papers on the rockburst mechanism, as well as its prevention and control. All interested authors are welcome to submit manuscripts on (but not limited to) the following topics: (1) rockburst mechanism studies using laboratory tests, analytical analysis, and numerical modeling, (2) seismic methods for burst risk assessment and hazard forecast, and (3) innovative hazard prevention and control techniques in field applications.

In view of the high-level, thick, and hard roof in a mine in Shaanxi, it is difficult for existing technology to solve the problem of frequent rock bursts, which are caused by the direct weakening of the whole underground layer. In this paper, a technology for preventing rock bursts using the long-distance drilling and blasting of a thick and hard roof in a high drilling field is proposed. The authors used theoretical analyses, numerical simulations, and other research methods to analyze the mechanisms of pressure relief and load reduction achieved by this technology, determined its layout parameters and layers, and carried out engineering practices in 2412 working faces in a mine in Shaanxi. The results show that the long-distance drilling and blasting technology can achieve the aim of unloading the pressure drop load by arranging a high-level drilling field to achieve the whole-layer presplitting of the thick and hard roof above the working face. According to the orthogonal test method, when using long-distance drilling and blasting under the condition of a high-level roof, the choice of the blasting layer is the biggest factor affecting the change in overburden subsidence. Using the identification basis of the main control disaster causing the layer of overburden, it was determined that 52~67 m above the coal seam of the 2412 working faces was the blasting layer. According to the periodic weighting interval of the working face and the development radius of the fractures in the blasting surrounding rock, the blast hole spacing was determined to be 30 m. After long-distance drilling and blasting, the frequency and energy of micro seismic events were reduced, the entry deformation was reduced compared with the common roof deep-hole blasting technology, and the pressure relief effect of the long-distance drilling and blasting technology was better. These research conclusions can provide theoretical support for the prevention and control of rock bursts during mining production under similar conditions by reducing the load and the unloading pressure on thick and hard roof layers that are difficult to unload from the source.
