... Abstract The geothermal energy extraction using the fracture-type reservoir in deep crust more than 350–400 °C is suggested. When using the fracture-type reservoir, there is a possibility of aseismic slip rather than seismic slip. However, characteristic and influence on permeability...

... characteristics, various tunnel collapses were systematically classified in this paper through the collection and analysis of the tunnel collapses. They can be classified as mountain tunnel collapses, urban tunnel collapses or submerged tunnel collapses; collapses caused by stability of surrounding rock or caused...

... Abstract The distribution and evolution characteristic of abutment pressure is a key factor to controlling surrounding rock-mass in underground coal mining. Aiming to analyze the formation mechanism and dynamic evolution characteristic of abutment pressure, different surrounding rock-mass...

... to analyze the dynamic inflating characteristic of steel materials. It was concluded that the STKM11A material, along with the other steel materials, is selected for the material of the steel tube rockbolt. The STKM11A steel tube rockbolts were installed in the thick steel tube to perform the pullout tests...
