Abstract Development of the study of the structure failure of mining rock and its movement are briefly reviewed;and it is found that the structure failure of mining rock and its movement not only control the strata behaviors in working face and mining roadways,but also control strata movement,ground subsidence,crack evolution and seepage in mining strata. With the deep study of the law of specific mechanical behaviors of mining rock,series of technological innovations in mining engineering are formed according to utilizing and controlling these specific mechanical behaviors;and a set of results are listed by means of engineering legend. Four innovative technologies and their developing processes,latest developments,important technological parameter indices and so on are summarized,such as the solid filling technology with waste in fully-mechanized coal mining and the quick filling technology in gob-side entry retaining with large section developed based on the law of strata movement and ground subsidence,and the technique of coal mining and gas extraction and the technique of water-preserved mining developed based on the law of crack evolution and seepage in mining strata.
