The invention provides a water guide groove for a mining working face of a coal mine capable of preventing silting. The water guide groove comprises a coal residue storage bucket, water leaking holes,rubber antiskid pads, rubber antiskid blocks, air intake holes, rescue handles and blocking blocks, wherein the trapezoidal water guide groove is of an inverted trapezoidal groove structure, and thebottom part of the trapezoidal water guide groove is provided with a plurality of bucket storage grooves; each coal residue storage bucket is of a bucket structure, and a plurality of groups of waterleaking holes are formed in the bottom part of the coal residue storage bucket; the rubber antiskid pads are respectively arranged at both sides of the top part of the trapezoidal water guide groove;the multiple groups of residue handles are respectively arranged at the two sides of the groove wall of the trapezoidal water guide groove; the multiple blocking blocks are arranged at the bottom partof the trapezoidal water guide groove. The water guide groove has the advantages that by arranging the air intake holes and air ventilating holes, the air in the coal mine can be circulated, so thatthe internal gas density is reduced, the probability of gas explosion is reduced, and the safety of workers is effectively protected; when the coal mine collapses, the trapped persons can breath the external fresh air via the air ventilation holes, so that the survival probability of the trapped persons is improved.
