Anchor production process was also considered to improve gradient strength of materials which can better adapt to the rock burst environment.
Researches by Scholars [4~6] under the dynamic conditions of the support design were focused more on supporting materials and supporting methods than on support optimization.
Bolt material is optimized to improve the gradient strength.

The used phase change materials mainly includes CaCl2·6H2O, Na2SO4·10H2O and paraffin wax etc.
The first important application in buildings is taking phase change materials as indoor heat insulation materials by means of thermal energy storage device installed in the room, or “adding” phase change materials in the walls, doors, windows, ceilings or under floors.
The second important application in buildings is combining phase change materials with construction materials, thus forming multi-functional materials.
