Mechanical Behavior and Response Characteristics of Overlying Strata in Remining Longwall Top‐Coal Caving Working Face

Energy Science &Engineering, EarlyView.
ABSTRACT In the remining working face of thick coal seams, the instability of coal pillars near abandoned roadways can lead to advance fractures in the main roof, posing a significant threat to production safety. This study classifies roof collapse characteristics into four types and analyses the pillar instability mechanism using the Bieniawski ...

A Novel Gas Extraction Technique in Coal Seams Utilizing Hydraulic Fracturing‐Dissolution and Analysis of Non‐Uniform Propagation of Fracture

Energy Science &Engineering, EarlyView.
ABSTRACT Extracting gas from low‐permeability coal seams is essential for mine safety and efficiency. To address this challenge, a novel technique combining hydraulic fracturing and dissolution was proposed. The feasibility of this method was verified through simulations based on the distinct element method.
