Micro-structure of crushed coal with different
网页2020年8月1日Affected by the mining activities, a large amount of spontaneous combustion coal is crushed to generate internal fractures. As a result, the crushed coal is exposed to the airflow and begins to engage in low-temperature oxidation. Under good heat storage conditions, CSC is likely to occur and eventually leads to major mine disasters.

Dynamics of the Ice-Crushing Process Journal of
网页2017年1月20日1.Introduction. Ice is an extremely brittle material. Yet at very low loading rates, ice creeps, dissipating energy mainly as heat. This is not a result of the loading rate per se, but rather the result of the fact that the creep process keeps the load, and consequently the strain-energy density, at a level low enough to preclude fracture.Once
