The invention relates to an embossed draining floor mat and a production process thereof. The embossed draining floor mat comprises a floor mat body, wherein a plurality of ribs are arranged at the bottom part of the floor mat body, and a plurality of hollow holes are formed in the floor mat body between the ribs. PVC (polyvinyl chloride), plasticizers and stabilizers are uniformly stirred in a certain proportion; then the mixture is sent into an extruder for sheet extrusion, and sheets are rolled at the same time, accordingly, the hollow holes and the ribs are formed on the floor mat body; then the bottom part and the surface part of the floor mat body are subjected to bottom cutting and surface cutting, and then the floor mat body is sent into a hot melting machine for hot melting and embossing on the front surface of the floor mat body. The plurality of ribs are arranged at the bottom part of the floor mat disclosed by the invention, and the hollow holes are formed in the surface of the floor mat body, so that good ventilation and water draining performances are achieved for the bottom part of the floor mat, the lower part of the floor mat keeps dry and ventilative, and mildewing is prevented; the embossed draining floor mat adopts processes, including extruding, rolling, hot melting and embossing, are used, so that the production process of the floor mat is greatly optimized; meanwhile, the embossed patterns have an anti-skidding function, therefore, the embossed draining floor mat has the advantages of being attractive in appearance, environment-friendly, sanitary, ventilative, water-repellent and anti-skidding.
