| Abstract: | Pointing to difficulties met in first overhead caving in hard roofing in 374 working plane, countermeasures under coercion are carried out, and mine pressure is monitored at the same time. Pressure rule showed in first caving is studied in this paper, thus, damages which will happen in first caving can be decreased. |
