In orde to obtain system optimization in high efficiency production and operation safety, the microcosmic problem of goaf treatment was brought into the creative design of mining method and the synergism of two problems was studied. Firstly, in view of the occurrence characteristics and mining conditions of catacalstic ore section of orebody No. 105 in Gaofeng mine in Guangxi province, considering the adaptability to different scale goafs in the ore section, based on mining environment reconstructing idea and continuous mining mode, a new mining method (mining environment reconstructing non-pillar sublevel-strip continuous mining method) was put forward. Then, some repr, esentative goafs were selected and their stabilities were calculated by discrete element method on the basis of differences of goaf scale, surrounding conditions and situ stress field. At last, the mining layout was adjusted on the basis of goafs stability analysis and the goafs were adjusted as a part of cutting engineering, blasting space or stope, so as to determine all kinds of goafs treatment schemes.

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.
