Research on the Laws of Destructive Patterns and Control Measures of Overlying Rock in High‐Efficiency Large‐Scale Mining Faces

Energy Science &Engineering, EarlyView.
With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance

Improvement of Coal Mining-Induced Subsidence-Affected (MISA) Zone Irregular Boundary Delineation by MT-InSAR Techniques, UAV Photogrammetry, and Field Investigation

Remote Sensing
Coal mining-induced ground subsidence is a severe hazard that can damage property, infrastructure, and the environment in the vicinity when the deformation is not negligible.

Investigation of the Dynamic Evolution Mechanism of Bed Separation in Karst Aquifers and Risk Assessment of Water Inrush

Energy Science &Engineering, EarlyView.
This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

Study on the mechanism and control of ground subsidence induced by solution mining in Guangzhou Longgui Nitrate-Salt Mine

Frontiers in Materials
Solution mining is widely applied in underground salt rock extraction, but it is prone to inducing ground subsidence. Under complex geological conditions, its mechanism is more complicated, posing a significant threat to engineering safety and the ...

Experimental and Theoretical Investigation on the Progressive Breaking Law of Thick and Hard Rock Strata in Deep Mining

Energy Science &Engineering, EarlyView.
This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...

Failure Characteristic and Stability Control of Gob‐Side Entry Retention With Narrow Roadside Filling Wall

Energy Science &Engineering, EarlyView.
A novel collaborative control technology of gob‐side entry retention with narrow roadside filling wall is proposed, wherein anchoring end of anchor cable must penetrate the boundary line of stress peak (plastic zone). ABSTRACT Gob‐side entry retention represents a major technological innovation in the history of coal mining, offering numerous ...
