Function of Self Drilling Ground Anchor
As a basic constituent part of roadway support in coal mine, self drilling ground anchor constraints surrounding rocks to support itself. Nowadays, self drilling ground anchor is not only used in mine, but also in engineering technology, providing active reinforcement for slope, tunnel and dam.

Through longitudinal pulling force, self drilling ground anchor can overcome the shortcoming of soil body’s tensile capacity far below anti-pressure ability.

Seemingly, it limits rock and soil separating from original body; at the microscopic level, it increases cohesiveness of rock-soil body; from the standpoint of mechanics, it enhances surrounding rocks’ cohesiveness and internal friction angle.

Substantially, self drilling ground anchor and rock-soil body form a new compound, which can solve low tensile capacity and make carrying capacity stronger.
