The present invention discloses a dynamic and static load combined rock breaking test apparatus and a test method. The test apparatus mainly comprises an axial feed cylinder, a fixed platform, a piston rod, a guide pillar, a displacement sensor, a lifting platform, a torque sensor, a grip cylinder, a base, a rotary impact mechanism assembly, a drive motor, a quartz piezoelectric sensor, a drill stem, a micro-drill, a rock sample, a guide rail motor, a cross guide rail, a bit weight sensor, a confining pressure sensor, a computer, a control cabinet and a hydraulic power unit. The axial feed cylinder drives the lifting platform to slide up and down. The drive motor drives the rotary percussion mechanism assembly to apply rotational motion or rotary percussion motion to the micro-drill. The grip cylinder applies a confining pressure to the rock sample. The guide rail motor adjusts the position of the rock sample. The bit weight sensor, the confining pressure sensor, the displacement sensor, the torque sensor, and the quartz piezoelectric sensor are all connected to the computer. The dynamic and static load combined rock breaking test apparatus and the test method can comprehensively simulate various rock breaking states of a drill in a drilling process, and provide a theoretical basis for determining downhole acceleration tool performance parameters and field drilling parameters.
