Based on the geological conditions and mining parameters of the coal mining face in No.12 mining block of Jining No.3 Mine,a similar simulation in the lab was conducted on the mining process of the coal mining face in the uper liberated seam.In combination with the site measured results,the pressure releasing function of the uper liberated seam mining to the low seam was analyzed.The study results showed that after the liberated seam mined,selling and deformation occurred in the low seam and… Expand
Analysis of Pressure Relief Effect on the Protective Layer of Hard Roof and Extra-Thickness Coal Seam Mining
The roof of Tashan coal mine was hard and difficult to fall. In the process of fully mechanized coal caving in the Carboniferous extra-thick coal seam, the strong pressure and rock burst appeared inExpand
Layout of the First-Mining Working Face in the Protected Seam for Pressure Relief by Peak Stress Shift
An appropriate layout of the first-mining working face of protected seams is key to rockburst prevention in coal seams. By taking the first-mining working face in the 2-2# middle coal seam in HulusuExpand
Prevention of rock burst by protective seam mining in high-depth strata: a case study
Several rock burst accidents occurred during the excavation of the 4th seam in a mine. Based on the geological and mining conditions of the mine, numerical simulation methods was adopted to analysisExpand
Analysis on Rock Burst Risks and Prevention of a 54 m-Wide Coal Pillar for Roadway Protection in a Fully Mechanized Top-Coal Caving Face
A case study based on the 401103 fully mechanized caving face in the Hujiahe Coal Mine was carried out in this research to analyze the rock burst risks in a 54 m-wide coal pillar for roadwayExpand
