Avoiding Porosity in Mining Engineering Castings ChinaSavvy

In mining engineering, porosity of casted parts has the following disadvantages: Because of the small voids within the part, the part becomes less stable. This is because the density of the particles that are melted together, is not uniformed or balanced. Porosity causes weakness in the material used in the casting process.

A Coupled Nonlinear Flow Model for Particle Migration and

A large number of statistics indicate that broken rock mass always transforms into a flowing channel and leads to water inrush disasters in mining engineering, such as fault, karst, and strongly weathered rock mass. During the process of water inrush, the structure of the broken rock mass is constantly changing due to seepage erosion under high-velocity flow.
