Rock mass collapse monitoring method

The invention relates to a rock mass collapse monitoring method which is completed by using auxiliary equipment in a matching way. The auxiliary equipment comprises a mounting frame, the upper end ofthe mounting frame is of an opening structure, a guide conveying pipe is mounted on the mounting frame, and a tight insertion mechanism is arranged at the left end of the mounting frame. The followingproblems in the existing rock mass collapse monitoring process can be solved: a, a timber pile needs to be manually inserted into a circular hole drilled in a rock mass in advance, the impact force of the timber pile on the foremost end of the circular hole in the inserting operation is large, a gap is reserved between the timber pile and the circular hole due to the fact that the circular hole is easily expanded or the timber pile deforms, small timber piles need to be manually inserted into gaps to be filled, the labor intensity b is increased, a traditional monitoring method cannot be single in mode, the monitoring
