Practice on No Pillar Simultaneous Extraction of Coal and Gas in Deep Mine
Based on four typical mining condition, such as implementation gob-side entry retaining under sandstone roof, long length and long time gob-side entry retaining, implementation gob-side entry retaining under mudstone roof and implementation gob-side entry retaining at depth of more than 900 m, this paper analysis the roadway maintenance-control in no pillar simultaneous extraction of coal and gas engineering, research on the roadway maintenance-control technology during exploitation and before mining, further study typical convergence characteristics of gob-side entry retaining after mining, drew in application of no pillar simultaneous extraction of coal and gas in deep mine, proposed evaluation about the project current existing problems and development trends.
