Safe and efficient suspended roof treatment method adopting sublevel open-stoping subsequent filling mining method

The invention discloses a safe and efficient suspended roof treatment method adopting a sublevel open-stope subsequent filling mining method. The method comprises the following steps: S1, judging whether a stope is suspended; s2, scanning a goaf: carrying out three-dimensional laser scanning on the goaf and surrounding roadways in cooperation with related personnel of a geological survey department in an underground stope; s3, sorting data: processing the three-dimensional laser scanning data on software, and integrating the processed three-dimensional laser scanning data and a stope monomer design CAD drawing to DIMINE software for drawing; s4, analyzing the model: analyzing an appropriate hole patching scheme by combining the'stope design model 'and the'roadway model' with the'three-dimensional goaf model ', and directly designing the most appropriate hole patching and blasting design on the software by utilizing the mining plate function of the DIMINE software; s5, on-site checking: measuring personnel des
