In order to reduce the volmne, the trader-well rescue imclmnism is modularizing designed. At the same tirae, the audio and video systyems, the illumination system and the ventilation system are expatiated. The rescuing robot can rescue the falling person in the deep well, it can save much manateral resources and time. It＇s really an ideal rescue device for the small-caliber fall.展开更多

The suggested methods were applied to a deep rock roadway with -648 m depth in Gubei coal mine of Huainan area. The field test was carried out and the in-situ monitoring was imple- mented, and the support scheme was optimized and adjusted to improve the stability of the surrounding rock of the roadway based on the feedback analysis. The results showed that the stability can be improved greatly by the provided control methods tbr deep roadway. The present methods lbr stability control of deep rock roadway can be used to other deep rock roadways with the similar conditions.展开更多
