Variation Characteristics of Mass-Loss Rate in Dynamic ...

When the collapse column and its adjacent rocks in complex geological structures are disturbed by mining, concomitant fine particle migration, mass loss, and porous structure variation during the water seepage process in broken rocks are the inherent causes for collapse column activation and water inrush. Studying the time-varying characteristics of the mass-loss rate in the dynamic seepage ...

The results show that: 1) at the 0.001mm/s rate, the particle size of the broken coal is small, which is a complete and full failure, and the failure type belongs to plastic failure. Under the 0.1mm/s loading rate, the size of the failure fragment is the largest and the shape is irregular, which is incomplete and inadequate, and the failure type belongs to brittle failure.

Polyethylene and biodegradable mulches for …

2011-12-16 · The use of plastic mulch in agriculture has increased dramatically in the last 10 years throughout the world. This increase is due to benefits such as increase in soil temperature, reduced weed pressure, moisture conservation, reduction of certain insect pests, higher crop yields, and more efficient use of soil nutrients. However, disposing of used plastic films, which cause pollution, has led ...

Soil Washing | Geoengineer

Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine …
