缓倾斜煤层工作面矿压显现规律及过断层技术研究

Study on the Law of Mine Pressure Appearance and the Technology of Passing through Fault in the Face of Gently Inclined Coal Seam

针对5102工作面矿压显现规律和过断层技术措施,采用现场实测、理论分析进行了研究,发现顶板压力和来压持续时间随着倾角变大而变大,来压步距随着倾角变大而减小。采取了针对性的工作面过断层技术措施,提高了生产效率和顶煤回收率,实现了煤矿安全、高产、高效开采。

According to the law of the coal pressure appearance and the technical measures of passing through the fault in 5102 working face, the field measurement and theoretical analysis are adopted to study. It is found that in the gently inclined coal seam with fault, the roof pressure and the duration of the incoming pressure increase with the increase of the dip angle, and the incoming pressure step decreases with the increase of the dip angle. The technical measures of working face passing through fault are adopted to improve production efficiency and top coal recovery rate, and realize safe, high-yield and high-efficiency mining of coal mine.
