Article Abstract
The hazardous effect of a mine earthquake on a roadway is not only related to its energy scale but also to its distance from the roadway. In this study, a signal attenuation model and a disaster-causing model were established to evaluate the mine earthquake effects based on peak particle velocity (PPV) data recorded for 37221-1 upper roadway of the Dongxia Coal Mine, China. The characteristic of dynamic loads due to mine earthquake propagation to roadway surfaces was researched, and critical PPV values were identified using FLAC numerical simulation, which can be used to evaluate the roadway anti-burst performance under the existing support system. The results show that the support system is able to resist a mine earthquake with energy below 2.33 × 10 J; however, considering the energy accumulation volume of surrounding rocks and the range of source fracture, the maximum resistible mine earthquake energy can be up to 7.09 × 10 J when the roadway is 50 m away from the source. The validity and applicability of the disaster-causing models was verified by two rockburst cases that occurred during the excavation of the working face.

Time domain induced polarization (TDIP) method is an important geophysical exploration technique for metal exploration. It is common to collect resistivity/IP data using a gradient array. However, the depth of investigation of a typical gradient array survey is limited by a single fixed transmitter electrode distance, which only provides information over a limited range of depths.

Voluminous Miocene silicic volcanism sourced mainly from the extensional Pannonian Basin played a major role in the evolution of the Central Paratethys. Here, we identify a widely distributed (> 3150 km) member of the Upper Rhyolite Tuff in Hungary, called the Dobi Ignimbrite, with a precise sanidine/plagioclase Ar/Ar age of 13.064 ± 0.

The mining of extra-thick coal seams is prone to triggering mine earthquake, which causes damage to surface buildings and severely restricts the sustainable development of coal mines. This study constructs a spatial structural model of hard rock tearing-type fracture at the 61,607 working face in Longwanggou Coal Mine. Through analytical modeling of stress-energy characteristics during fracture propagation, we quantitatively estimate the vibrational energy partitioning within rock mass discontinuities and evaluate the maximum potential magnitude (ML) of mine earthquake.
