Analysis on rock burst danger when fully-mechanized caving coal face passed fault with deep mining
Rock burst Microseism monitoring system Fault Numerical simulation
2012/3/27
When fully-mechanized caving face passed fault, rock burst accidence easily occurred. The SOS microseism monitoring system was applied to monitor the microseismic activities all time occurred in the c...
Stability and deformation of surrounding rock in pillarless gob-side entry retaining
Gob-side entry retaining Surrounding rock Structural stability condition Deformation impact factor
2012/3/27
We analyzed the stability of the retained gob-side entry in four different Chinese coal mining sites and evaluated the influencing factors of roadway deformation such as mining depth, support strength...
Relationship between EMR and dissipated energy of coal rock mass during cyclic loading process
Coal rock mass EMR energy Dissipated energy Hysteresis loop area Amplitude
2012/3/28
Dynamic collapses of deeply mined coal rocks are severe threats to miners. In order to predict the collapses more accurately using electromagnetic radiation (EMR), this paper researched the energy con...
Changing regularity of rock damage variable and resistivity under loading condition
Rock damage Resistivity Relation equation Acoustic emission
2012/3/28
In this paper, the stress–strain, resistivity and acoustic emission simultaneous test of compression test for rock have been carried out to obtain the regression equation between the resistivity, and ...
Research progress on electromagnetic radiation in gas-containing coal and rock fracture and its applications
Gas-containing coal and rock fracture Electromagnetic radiation Research progress
2012/3/28
This paper reviews the status quo of the research on electromagnetic radiation in gas-containing coal and rock fracture. It focuses mainly on the electromagnetic radiation phenomena, the generation me...
Experimental study on non-destructive testing of rock bolts based on pseudo-random signal
Pseudo-random signal Rock bolts Non-destructive testing Correlation analysis
2012/3/28
The quality of rock bolt anchoring is closely related to the stability and safety of underground engineering and slope protection. In this paper, non-destructive testing of rock bolts is proposed base...
Study on tri-axial creep experiment and constitutive relation of different rock salt
Rock salt Salt cavern Creep character Burgers model Safety and stability
2012/3/31
To evaluate the effect of the long-term operation of a salt cavern in a given construction on rock deformation and its stability, tri-axial creep tests to the glauberite, anhydrite, and argillaceous r...
