Its features are: 1) use weeds, sacks and synthetic fibre instead of ore isolation layer; 2) put dry-type filling material down from ventilation roadway, and keep ore caving ratio match the filling rate to ensure the filling material and ore are synchronous uniform sinking for reducing ore dilution and loss rate.
Until the isolation layer moved until to a certain extent; Then, the stable isolation material beard the filling stone, meanwhile, the ore around the opening of a discharge hopper flowed gradually and finally a cavity with small areas was formed until ore cumulates according to natural repose angle.

The beam, plate and the column etc component section which are lack of capacity should be retrofitted with FRP materials preferentially.
In addition, it is not suitable for the column to be retrofitted with FRP materials with ultra-limited axial compression ratio but some another method is fine such as increasing the column section etc.

Bi-coating effect of optical excitation When the whole resonator is made of two materials and must be analyzed as bi-layered structure, there are two main mechanisms that allow the resonance to be excited photo-thermally.
Based on the ‘Equivalent methods of parameters’ in vibration theory, the frequency of the micro resonators can be expressed as[4] (5) Where K0 is a coefficient related to the parameters of such a bi-material micro resonator, which is (6) Theoretical amplitude of bi-layered micro resonator When the whole resonator is made of two materials and must be analyzed as bi-layered structure, there are two main mechanisms in optical excitation.
