摘　　要：未来热害矿井隔热降温研究方向之一,即使用新型廉价无机、非阻燃隔热材料。以蛭石砂浆隔热材料为例,研究了最优配比下的材料组成形态及性能,并且结合热害矿井轨道石门现场工程应用得出:在表面喷射蛭石砂浆可以有效降低风流的增温幅度,且在蛭石砂浆喷层为6 cm时,风流增温幅度最小,效果最好。The use of the new type cheap inorganic insulation,non- fire- retardant insulation materials was one of future heat insulation and cooling research directions in heat harmful mines. In this paper,it took the vermiculite mortar insulation materials as the example,studied the material composition morphology and performance under optimal ratio. Combined with the site engineering applications of track cross- cut in heat harmful mines,it obtained that the vermiculite mortar spray on the surface of the injection could effectively reduce the airflow warming magnitude. When the sprayed layer thickness of vermiculite mortar was 6cm,the airflow warming magnitude was smallest,and the results were best.
