Abstract By analyzing the hazard of water flushing from Ordovician limestone in deep coal mine of Fengfeng group,the prevention and control system of＂seven module integrated＂,which included system construction,institution establishment,base safeguard,direction,partition,advanced management and evaluation before mining,applying to Ordovician limestone water damage of deep coal was built and made the prevention and control of Ordovician limestone water damage from the passive control to proactive prevention.The popularization and implementation of this system in Fengfeng group show that this system effectively suppresses the happening of Ordovician limestone water damage,achieves good effect and ensures production safety.

Key words deep coal mine,Ordovician limestone water damage,proactive prevention,＂seven module integrated＂prevention and control system

峰峰矿区属于我国华北岩溶型大水矿区,承受着多种水害的威胁,突水因素多且复杂,尤其受底板奧灰水害的威胁程度极其严重,近10年来,峰峰矿区的牛儿庄、九龙、黄沙和梧桐庄矿多次发生过特大奥灰突水灾害,造成了巨大的经济损失.随着矿井开采深度逐渐加大,在大地压和高水压的联合作用下,奧灰突水的几率大大增加,矿井面临的奧灰水害问题更加严重.目前峰峰矿区各矿井基本处于煤田的深部,开采深度在800 m左右,开采煤层底板承受奥灰水压高达8.0～10.0 MPa,传统的奧灰水害防治体系已经不再适应目前采深大、水文地质条件更加复杂的开采环境,探讨总结一套适合深部矿井复杂条件下的奧灰水害防治体系显得尤为必要,且具有十分……
