The control system comprises a pressure sensor and a controller, wherein the pressure sensor is arranged at the position of an oil inlet of a power head hydraulic motor and used for measuring working pressure of a drilling system, and the controller is connected with the pressure sensor in a sampling mode and used for receiving pressure signals of the pressure sensor and then controlling rotating speeds of a master winch to control lowering speeds of a drill. The utility model further relates to a long spiral drilling machine. According to the control system of the drilling machine and the long spiral drilling machine, during the process of the drilling machine drilling, the controller receives the pressure signals collected by the pressure sensor and compares the pressure signals with the set working pressure of the drilling system; when the collected working pressure of the drilling system is smaller than the set working pressure of the drilling system, the master winch is controlled to accelerate the lowering speeds of the drill so as to improve drilling efficiencies; and when the collected working pressure of the drilling system is larger than the set working pressure of the drilling system, the master winch is controlled to reduce the lowering speeds of the drill to prevent the drill from snapping so that operators are not required for watching during the drilling machine drilling, and automatic drilling is achieved.
