  avalanche angle
The numerical calculations of the avalanche angle as a function of the undersaturated pressure of heptane or water are in good agreement with the experimental results.
      
Ageing of the avalanche angle in immersed granular matter
      
The avalanche angle depends on the time during which the system remains at rest before measurement only when the grains are immersed in water.
      
A model based on the block dynamics is proposed to describe the behavior of the avalanche angle as a function of the size of the monolayer and the polydispersity of the beads.-1
      


Resulted from small caving angle produced in practising caving mining in Chenchao Iron Mine,the surface of east main shaft fractured severely,so the finite element analysis was made.It showed from analyzed result that the small caving angle was related to complicated terrain. With the forming of caving area,the slope foot was rid of support and a part of the shaft on the slope land was in the state of tensive stress,resulting in shaft cracking.The result of finite element analysis has provided theoretical basis...

D-FLAC software was used to establish the model for dynamic analysis of the ground deformation caused by underground mining, which was based on the technological flowsheet of caving method. The calculation results for Yuhuashi mining area at Jinshandian Iron Mine showed that mining at above -150 m level had small movement angle and caving angle and the deformation would become gentle when mining continued. The main factors affecting the ground deformation were found, the points needing attention in deep mining...
