Research on the Application of Polymer Plastic Materials in Coal Mine Air Leakage Control
In order to solve the problems of long solidification time,high dust concentration,and high rebound rate of traditional concrete materials that affect underground ventilation and airtightness,this paper proposed the application of KA-GK reinforced sealing ester material for sealing and plugging air leaks in underground coal mine tunnels.An analysis was conducted on the preparation requirements and raw material parameters of the material.According to practical applications underground,the new polymer plastic material has similar structural strength to traditional concrete,but has significant advantages in sealing and construction efficiency.
