The present invention relates to the field of coal-rock mass strength testing technologies, and particularly relates to a coal-rock mass strength in-situ testing apparatus. The coal-rock mass strengthin-situ testing apparatus comprises a housing, a first guide mechanism, a cutting mechanism, and a second guide mechanism. The cutting mechanism comprises a disk cutter and a first driving mechanismthat drives the disk cutter to protrude out of the housing. Each of the first guide mechanism and the second guide mechanism comprises a guide roller and a driving wheel. The guide roller and the driving wheel are correspondingly disposed on two opposite radial sides of the housing. The guide roller and the driving wheel can separately protrude out of the housing. The coal-rock mass strength in-situ testing apparatus provided in the present invention not only is convenient for operation and carrying, but also can directly perform in-situ test on coal-rock mass strength, and a test result is more true and accurate. 本发明涉
