THE GOAFS TREATMENT SCHEMES BASED ON STABILITY ANALYSS AND MINING LAYOUT IN CATACLASTIC ORE SECTION

摘要：

According to the differences of goafs scales, surrounding rock conditions and situ stress field, three representative kinds of goafs in cataclastic ore section were chosen and their stability was calculated by using discrete element program. In view of the occurrence characteristics and mining conditions of catacalstic ore section, a new mining method (mining environment reconstructing non-pillar continuous mining method) was designed creatively on the basis of mining environment reconstructing and continuously mining theory. Based on the stability analysis, the treatment schemes of different scale goafs were made out through flexibly adjusting mining layout.
