Hydraulic measures are widely used to improve coal seam permeability, but not all hydraulic have a positive effect on permeability in soft seams, and the permeability-enhancing of seams is clear. To further study mechanism compare punching reaming this takes Changping Mine, China, as its case study. A comparative analysis was conducted influence range gas extraction enhancement. The following conclusions were mainly drawn: mathematical calculation model established for strength impact...
The shear strength of a structural plane is critical parameter in the analysis engineering rock stability. Significant differences exist due to various normal stresses plane. Therefore, evaluating deformation effectively determine influence at different scales on planes great significance. This study discusses effects stress and size through numerical simulations regression analysis. results showed that increases linearly with increasing stress. decreases size, corresponding curve...
Abstract The experimental study on the variation law of coal fracture and stress was carried out in laboratory engineering fields, respectively. A multiparameter monitoring system including electromagnetic radiation a high‐speed camera built, three paths, uniaxial compression, cyclic loading, graded were used to monitor dynamic expansion process surface cracks during compression failure specimens. Through quantitative analysis signal crack propagation process, it is found that change trend...
This paper aims to study the law of pressure behavior and characteristics mutual influence in process steeply inclined coal seam mining. Based on geological engineering conditions B8 Nanshan mine, this explores mine mining by means theoretical analysis FLAC3D numerical simulation. this, also examines interaction range between seams, reasonable setting size section pillar, distance working face return air roadway. The results suggest as follows: (1) With an increase dip angle, difference...
