【摘要】：针对煤矿深部岩体断层滞后突水具有隐蔽性、滞后性及防治难度大等特点,结合王楼煤矿3采区13301工作面开采过程断层滞后突水治理工程,在水文地质和水源探查分析的基础上,研究了采动作用下断层滞后突水机理,研发了一种低成本水泥基注浆材料,能够保证工程突涌水治理需求,与普通水泥材料相比,节约了材料成本约60%。将新型水泥基注浆材料应用于断层滞后突水治理工程,结合注浆治理过程工作面涌水量变化及注浆效果关键评估技术,现场裂隙发育形成的导水通道被拦截,水力通道被阻断,有效控制了工作面涌水量,达到预期堵水效果。
[Abstract]:In view of the characteristics of delayed water inrush of deep rock mass fault in coal mine, such as concealment, lag and difficulty of prevention and treatment, combined with the project of fault lag water inrush in 13301 working face of No. 3 mining area of Wanglou Coal Mine, the project of water inrush with fault lag is discussed. On the basis of hydrogeology and water exploration and analysis, the mechanism of lag water inrush of fault used in mining action is studied, and a kind of low cost cement-based grouting material is developed, which can meet the demand of engineering water inrush treatment, compared with ordinary cement material. The material cost is saved about 60%. The new cement-based grouting material is applied to the project of fault lag water inrush treatment, combined with the key technology of water discharge change and grouting effect evaluation in the process of grouting treatment. The water diversion channel formed by the crack in the field is intercepted and the hydraulic channel is blocked, which effectively controls the water inflow of the working face and achieves the expected water shutoff effect.
