Beschreibung
Zusammenfassung:	The invention belongs to the technical field of coal mine roadway supporting, and discloses a supporting system and method for forming a mining area rectangular roadway roof combined rock beam. A mining area rectangular roadway is arranged along a coal seam roof, the roof is supported according to different roof rock stratum conditions, the supporting system and method for the roof combined rock beam are formed, the formed roof combined rock beam bears the load of the upper part of the roadway roof, and the mining area rectangular roadway roof is supported and stabilized. According to the supporting system and method for forming a mining area rectangular roadway roof combined rock beam, the supporting system and method for the roof combined rock beam are formed in a roadway roof rock stratum by combining specific roadway roof rock stratum conditions and utilizing the supporting effect of anchor rods and the like on the roof rock stratum; the formed roof combined rock beam utilizes the bearing principle and ef
