断层构造对煤层底板突水影响研究

Study on the influence of fault tectonics on the water inrush of coal seam floor

针对严重威胁矿井安全生产的底板突水事故,通过理论分析,研究断层对煤层底板突水的影响,并建立力学模型,分析断层突水的力学机理,最后,结合某矿实际生产条件,合理推测工作面方式煤柱宽度,为矿井的安全、高效生产奠定基础。

In view of floor water inrush accident what serious threat to mine safety in production, through theoretical analysis, the water-inrush from coal floor, the influence of the fault on and establish the mechanical model, analyses the mechanics mechanism of water inrush and fault in the end, combined with the mine actual production condition, reasonable speculation width of coal pillar mining way, lay the foundation for mine safety and efficient production.
