Zusammenfassung:	The utility model discloses an underground hole drilling anti-clamping drilling machine which is used under the condition of hydrogeologic hole drill of underground construction in a coal mine. The utility model comprises a drilling head, a drill core pipe, a drilling rod, a motor and an operating handle, wherein the front end of the drilling rod is connected with the drill core pipe and the back end of the drilling rod is connected with the motor. A simulated hammer-shaped hole expansion body is fixedly arranged on the drilling rod, and cutting teeth are evenly arranged on the hole expansion body. The utility model can effectively prevent holes from collapsing so as to lead clamping and drilling accidents.
