自七十年代初期以来,新型的无底柱分段崩落法在我国地下矿已得到迅速的推广采用。据不完全统计,国内采用这种采矿方法的矿山已有四十多个,其中仅黑色金属矿山即达三十几个,占该类地下矿总生产能力的63%左右。按照装运设备类别及分段高度的大小,目前国内所用无底柱分段崩落法总的有如下三种基本方案:
Since the early 1970s, a new type of subsea subsidence caving method has been rapidly adopted in underground mines in China. According to incomplete statistics, there are over 40 domestic mines that adopt this mining method, of which only about 30 are ferrous metal mines, accounting for about 63% of the total production capacity of such underground mines. In accordance with the type of shipping equipment and the size of sub-height, the current domestic use of non-pillar sub-caving method has the following three basic programs:
