Table 8 Determination of the impact tendency of coal samples after the action of different solutions.
Type of coal sample | Dynamic destruction time (ms) | Impact energy index | Uniaxial compressive strength (Mpa) |
---|---|---|---|
Raw coal | None | Vigorous | Vigorous |
Water-soaked coal samples | None | Vigorous | Vigorous |
IDS-soaked coal samples | None | Vigorous | Weak |
JFCS immersion coal sample | None | Vigorous | Weak |
Complex wetting agent soaking coal samples | None | None | None |
