倾斜矿体崩落法采矿塌落错动范围的圈定研究

Study on delimitation of the ground caved&moved range of inclined orebody

随着矿山开采技术的进步,对采用崩落法开采的地下金属矿山塌落错动范围研究提出了更高要求。基于矿体赋存特点,借助顶板渐进崩落理论开展了典型剖面的塌落错动范围的崩落角、移动角的计算,并依据移动角圈定了典型剖面的塌落错动范围,进而圈定了矿山的塌落错动范围。研究发现采用顶板渐进崩落理论方法相对于工程类比法,结果更精细化,保证了矿山开采安全。

With the development of mining technology,higher requirements of ground caved&moved range delineation have been put forward for underground metal mines.According to the characteristics of the orebody,this study carried out the calculation of caved angle and movedangle of caved&moved range of typical section with the help of roof progressive caving theory.Then the study delineated the caved&moved range of typical section according to the caved&moved angle and delineated the caved&moved range of mine.Compared with the engineering analogy method,this study found that the roof progressive caving theory method is more refined,which increases the safety of mining.
