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 ...

Study on the Energy Evolution and Stability of Roadway Surrounding Rock Under the “Simultaneous Mining–Driving” Condition

Energy Science &Engineering, EarlyView.
Based on theoretical analysis, the energy‐evolution behavior of the surrounding rock at various depths on the solid‐coal side of the 221303 material roadway during the “advancing‐toward‐mining” process was first clarified. Numerical simulations were then performed to validate and elaborate on the theoretical results.

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...
