“…More fragments can be observed after the failure of the specimen as the treatment temperature gradually increases. The degradation of specimen integrity after failure can be used as an indication to assess the thermal damage [16,34].…”

“…On the other hand, the permeability were found to generally increase with increasing temperature in the treatment [31,32]. The relation between dynamic properties of rocks and thermal damage were also investigated by some researchers and it was found that the dynamic characteristics were also significantly influenced by thermal damage [33,34]. The investigated rocks in the above studies included granite, marble, sandstone, limestone, gabbro, claystone, calcarenite, etc.…”

High temperature treatment has a significant influence on the mechanical behavior and the associated microcracking characteristic of rocks. A good understanding of the thermal damage effects on rock behavior is helpful for design and stability evaluation of engineering structures in the geothermal field. This paper studies the mechanical behavior and the acoustic emission (AE) characteristic of three typical rocks (i.e., sedimentary, metamorphic, and igneous), with an emphasis on how the difference in rock type (i.e., porosity and mineralogical composition) affects the rock behavior in response to thermal damage. Compression tests are carried out on rock specimens which are thermally damaged and AE monitoring is conducted during the compression tests. The mechanical properties including P-wave velocity, compressive strength, and Young’s modulus for the three rocks are found to generally show a decreasing trend as the temperature applied to the rock increases. However, these mechanical properties for quartz sandstone first increase to a certain extent and then decrease as the treatment temperature increases, which is mainly attributed to the high porosity of quartz sandstone. The results obtained from stress–strain curve, failure mode, and AE characteristic also show that the failure of quartz-rich rock (i.e., quartz sandstone and granite) is more brittle when compared with that of calcite-rich rock (i.e., marble). However, the ductility is enhanced to some extent as the treatment temperature increases for all the three examined rocks. Due to high brittleness of quartz sandstone and granite, more AE activities can be detected during loading and the recorded AE activities mostly accumulate when the stress approaches the peak strength, which is quite different from the results of marble.

“…With the increasing depth in underground engineering, high stress concentration, energy accumulation, and other adverse factors become increasingly prominent in some complex geological conditions during excavation and resource exploitation (Durrheim et al 1998;Feng et al 2017;Ranjith et al 2017;Wong et al 2017;Wang et al 2020;. The frequency of geological hazards such as rockburst is increasing under the effects of these potential adverse factors, which significantly endangers the safety of personnel and equipment (Ortlepp and Stacey 1994;Jiang et al 2010;Kaiser and Ming 2012;Panthi 2012;Zhou et al 2015;Gong et al 2018Gong et al , 2020Feng et al 2019).…”

To reveal the function of drilling pressure relief (DPR) in preventing rockbursts from the energy storage perspective, we investigated the rockburst proneness of red sandstone with different number and arrangement of prefabricated borehole via uniaxial compression tests. The experimental result revealed the failure intensity characteristics of specimen can be quantitatively described using the peak-strength strain energy storage index (PESI). The PESI of red sandstone specimens with boreholes decreased by 23.2%-70.2% compared with that of intact specimens, i.e. DPR can effectively reduce the rockburst proneness of rocks. Furthermore, the effects of the number and arrangement of boreholes on rockburst proneness were evaluated. The PESI decreased as the number of boreholes increased. When the arrangement angle with the loading direction changed from 90 to 27 and then to 0 , the PESI first decreased and then increased; when the arrangement angle with the loading direction was 27 , the efficiency of eliminating rockburst proneness and weakening peak compression strength was the best. The borehole arrangement angle affects rockburst proneness more than the number of boreholes does. This paper offers a novel approach of quantitatively evaluating the rockburst proneness of rocks after DPR and clarifies the effectiveness DPR in reducing the probability of rockbursts.

“…e mechanical behavior and failure mode of biotite granite under combined action of cycle loading and high temperature (20°C, 200°C, 400°C, and 600°C) were studied using a modified SHPB device [11]; test results revealed that a threshold temperature for biotite granite may have existed between 400°C and 600°C. Wong et al [12] found that the peak stress and fragment size of marble sample after heating were inversely related to the heating temperature, and most of energy was dissipated through plastic deformation. Liu and Xu [13] conducted dynamic impact tests on marble with various high temperatures and air pressures, and the relationship between dynamic stress-strain curve characteristic and failure mode was studied.…”

To study the effect of high temperature on the dynamic mechanical properties and energy evolution characteristic of limestone specimens, the basic physical parameters of limestone specimens that cool naturally after experiencing high temperatures of room temperature (25°C), 200°C, 400°C, and 600°C were tested. In addition, compression tests with 6 impact loading conditions were conducted using SHPB device. The changes of basic physical properties of limestone before and after temperature were analyzed, and the relationship among dynamic characteristic parameters, energy evolution characteristics, and temperature was discussed. Test results indicated that, with the increase of temperature, the surface color of specimen changed from gray-black to gray-white, and its volume increased, while the mass, density, and P-wave velocity of specimen decreased. The dynamic compressive stress-strain curve of limestone specimens after different high-temperature effects could be divided into three stages: elasticity stage, yield stage, and failure stage. Failure mode of specimen was in the form of spalling axial splitting, and the degree of fragmentation increased with the increase of the temperature and incident energy. With the increase of the temperature, the reflection energy, the absorption energy, the dynamic compressive strength, and dynamic elastic modulus of rock decreased, while its transmission energy, the dynamic peak strain, and strain rate increased. The dynamic compressive strength, dynamic elastic modulus, dynamic strain, and strain rate of limestone specimens all increased with the increase of incident energy, showing a quadratic function relationship.
