Abstract: In order to improve the problem of high temperature and humidity heat existing in the roadway of deep shaft
refuge,high temperature mine basalt-plant fiber composite heat-resistant material was prepared by using ordinary silicate cement,
fly ash,melon flake stone and fine sand aggregate as the basic material,basalt fiber and glass beads as the dopant,and
straw plant as the reinforcing reinforcing material. The optimal ratio of the composite heat-resistant material was studied by orthogonal
test,physical property test,and gray correlation degree analysis,and the heat-resistant material under this ratio was also
applied in engineering. The results show that:the optimal ratio of composite heat-resistant material is 0. 2% basalt fiber,
0. 2% anticorrosive plant fiber,7% ceramic grains,8% ceramic sand;composite heat-resistant material principle for the formation
of closed pores inside the material after the hydration reaction to make the air conductivity decrease;rigid basalt fiber and
flexible plant fiber hydration reaction randomly connects the formation of porous structure to form a mesh whole,which strengthens
the specimen strength and steeliness;fiber reinforcement will form a porous structure to form a net,which enhances the
strength and steeliness;fiber reinforcement will form a porous structure to form a net. Steel;fiber reinforcement will form a flower-
like structure of Al(OH)3·AlPO4 polymer,to further enhance the tensile strength of the material and endow the material
with flame retardant properties;through the selection of a typical thermal hazard mine for field tests,the maximum temperature difference between the field station is 4. 1 ℃,the application of the effect is good. The results of the study are of great significance
for the management of heat damage in high-temperature deep wells and the prevention and control of occupational diseases.
