Abstract: The traditional coal mining mode has the problems of excessive loss of coal resources and high stress concentration in coal pillar area. In order to solve the above problems, a new engineering structure is proposed based on the theory of mining damage control. Through the discussion of the mechanical mechanism of non-coal pillar self-forming roadway technology, the technical measures such as roof directional fracture induced pressure reduction technology and NPR bolt / cable support system are introduced, and the 110-type mining technology system of non-coal pillar self-forming roadway is put forward, which integrates the coal mining and tunneling operation process, reduces the demand of roadway tunneling in each coal mining face. Field verification results show that the 110 method releases and transfers the roof pressure by implementing the directional pre-cracking and roof cutting technology in front of the working face, and realizes the adaptive balance adjustment of the surrounding rock of the left-over roadway with the help of the natural pressure of the mine and the crumbling and expanding characteristics of the collapsed gangue, and effectively reduces the amount of roadway excavation in the mining area by about 50%, which significantly improves the mining efficiency.
