Energy Science &Engineering, EarlyView.This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Integrated pressure relief technology for rock burst and gas outburst coordinated control in ultra-thick coal seams under spatially isolated rock pillar areas [PDF]
With the increasing depth of coal mining and the complexity of mining technical conditions, some mines are facing dual dynamic disasters of rock burst and coal and gas outburst, which exhibits a mutually coupled inducing trend.

Conjecture about mechanism of butterfly-shape coal and gas outburst in excavation roadway
矿业科学学报, 2017 Referring to roadway butterfly shape rock burst mechanism and nonlinear dynamic system theory, a conjecture about butterfly-shape coal and gas outburst mechanism in excavation roadway has been made, In this conjecture, the mechanical essence of coal and ...

Mango Seed Valorization: Sustainable Source of Nutrients, Bioactives, and Value‐Added Applications
Food Chemistry International, EarlyView.Highlighting mango seed as a valuable yet overlooked by‐product, promoting its utilization and reducing agroindustrial waste. ABSTRACT Mango (Mangifera indica L.) is one of the most widely cultivated tropical fruits, generating large quantities of by‐products during processing, with mango seed representing 20%–25% of the whole fruit weight ...
