Introduction As the insulator material of the internal wall for SRM chambers, EPDM (Ethylene-Propylene- Diene Monomer) is the one of the most commonly used carbonized heat-insulating materials so far.
There are three reasons for using graphite as the material of the impacting ball: · High thermal capacity, thus it won’t change the carbon layer surface temperature on the impacting process

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.

While buffer analysis can be used for identifying the locations of hazardous chemical storage sites in relation to residents living area, and can facilitate the evaluation of the threatened area in the event of a leak or spill of hazardous materials.
What is GIS technology GIS is built upon knowledge from geography, cartography, computer science, mathematics, and etc.
The purpose is to facilitate the evaluation of the threatened area in the event of a leak or spill of hazardous materials.
In the works of coordinate the relation of environmental protection and war and military activity, MEP-GIS is not only technology but also science, not only a tool but also the method and the mode of thinking.
