Abstract

This paper proposes a method to control the heat transfer from the surrounding rock to the roadway, that is, a new type of thermal insulation mortar is laid on the wall of the roadway surrounding rock, and the optimal proportion of three additives in the thermal insulation mortar is determined through orthogonal experiments, and the basic experimental measurement of the thermal insulation mortar under the optimal proportion is carried out. The experimental results show that with the increase of the three admixtures, the thermal conductivity of thermal insulation mortar decreases significantly, and the compressive strength decreases. When the content of fly ash ceramsite is 96%, the content of basalt fiber is 16%, and the content of expanded vermiculite is 16%, the performance of the specimen is the best.
