The water in the overlying rock of seabed gold mine directly threats the exploitation safety. The strike drift at −135 m level of the Xinli mine district of Sanshandao gold mine in Shandong province, was selected to be the applicable site for high-

This paper conducts a preliminary study on the characteristic precursors of strong fracture occurred in the process before failure of brittle material specimens based on experimental results. First, strong fracture is defined by sudden variation of s

The effects and laws of microwave radiation (MWR) emitted from loaded coal samples under uniaxial compression were experimentally studied and theoretically analyzed. Experimental results showed that the loaded coals have MWR effect and could emit wit

Rock in the subsurface composed of rock matrix and pore fluid is a two-phase medium. So the effective elastic parameters of rock are influenced by rock matrix, pore structure and pore fluid. Therefore, in order to get the relationship between porosit

This study attempts to reveal the possible linkage between the critical failure-fracture and creep process of locked patches in a seimogenic fault. It suggests that the ratio of cumulative Benioff strain of the fracture point to that of the start poi

This paper analyzed and studied the large di differences between rock fracture and failure which were seldom discussed in experimental seismology studies. It is pointed out that only taking the rock failure experiment to simulate the earthquake, espe

Fluid detection in fractured medium has great significance for the oil gas prospecting and exploitation. The weakness ratio of fractures is relevant with the fluid in fractures and it is very sensitive to the velocity ratio. Through analyzing the rel

In order to understand the relationship between earthquake occurrence and crustal heterogeneities, we used 107401 P- and 19624 S-wave high-quality arrival times from the 1992 Landers aftershocks and other local earthquakes which were recorded by both

Effects of temperature and strain rate on fracture strength of rocks are studied based on available experiment data, and a new empirical formula for the fracture strength of some typical rocks in the lithosphere is obtained. The effects of the confin
