Abstract:

abstract: This paper introduces a new type of rockbolt which with the special function of heat pipe,the rockbolt can promote the roadway surrounding rock and the air heat exchange rate,then self-regulation the air temperature in the roadway. The principle of rockbolt with heat pipe was proved to be correct by the numerical model.
