摘要:

摘 要:采用理论分析和现场实测相结合的方法,分析了工作面顶板涌水与顶板活动规律的相关关系。研究结果表明:采场顶板破断运动已波及上部含水层,工作面涌水水源主要为顶板砂岩裂隙水;顶板砂岩水的涌出量随工作面推进具有周期性的波动变化规律,与顶板的破断失稳规律具有很好的一致性,顶板的破断失稳运动造成覆岩水的流动与突变,顶板水涌出量与顶板富水性的强弱有关。根据顶板的富水性强弱和顶板的破断失稳规律,可进行顶板水涌出的预测和控制。

Abstract:

Abstract: Theoretical analysis and engineering exploration are adopted to study the relationship of roof water-gushing and roof movement law. The results show that stope roof breaking movement has spread to the upper aquifer, the gush source in the working face mainly was gritstone fractrure water; Emission of water from sandstone roof has a periodic fluctuation law and a good consistency with the roof rupture instability with the face-advancing, fracture of roof caused overlying strata water flow and mutation, in addition, emission of water also relate to water abundance of the roof. According to the water abundance and buckling and breaking rules of the roof, water gush of the roof can be predicted and controlled.

Key words: water gush of the roof, movement of the roof, influence law
