The anti-slip material provided by the present invention is prepared by the following formula: by weight, primer, 2 parts to 4 parts; binder, 23 parts to 30 parts; curing agent, 1 part; oxygen barrier agent, 1 part; retarder, 1 part; topcoat, 1 part to 2 parts; filler, 19 parts to 37 parts; pigment, 18 parts to 24 parts; fine aggregate, 19 parts to 41 parts; coarse aggregate, 24 parts to 51 parts. The beneficial effects are that the anti-slip material can effectively solve the technical problems of the safe mining of mines such as the hardening and cracking of the underground road surface, serious wear, obstruction of the construction process, and high construction intensity.
[0003] However, there are also some problems with the anti-slip material and the road surface treatment method using the same. For example, after a period of use, the paved road will be covered with a layer of water mist, resulting in a decrease in anti-slip performance and affecting traffic safety. Moreover, after laying, the adhesion force to the well is limited and it is easy to peel off. At the same time, due to the particularity of the mine, it needs to have the ability of anti-static electricity, but the above patent is not convenient to optimize again. Summary of the Invention
[0004] Based on the problems of poor anti-slip performance, limited adhesion force, and lack of anti-static electricity ability in the background art, the present invention proposes an anti-slip material laying process applied to mines.

7. A skid-resistant material laying process applied to a mine according to claim 1, characterized in that, In S1, the preparation method of the anti-slip layer: Obtain alumina ceramic particles and cordierite ceramic particles, and treat the surfaces of the alumina ceramic particles and cordierite ceramic particles with quartz sand of 120-200 mesh to form a microscopic uneven structure with a roughness Ra≥30μm, increasing the mechanical interlocking area by more than 40%.
