Application research deep well coal roadway anchor support and its project

With the non-line finite element method, the numberical value calculation on the stress and deformation of surrounding rock of deep mine roadways has been presented.

Nowadays support technology in deep roadway is an important topic and this paper analyses stable factors and example of deepoadway and achieves some effects.

Design of water plugging project in underground deep workings in pyrite mine;

For researching supporting technology problems of deep roadway,Continuity mechanics was applied to analyzing stability of roadway in deep mine by comprehensively analyzing status quo of supporting deep roadway and elastic and plastic displacement of surrounding rock of roadway were calculated.
