| Abstract: | By field observation and simulating test of shallow seam longwall mining,the phenomenon of main roof asymmetry breaking is discovered during the first weighting.Based on simulating model test and theoretical analysis,the mechanism of main roof first breaking is revealed,and the asymmetry breaking parameter is determined. |
| Keywords: | key stratum of main roof first breaking asymmetry mechanism |
