Research and Practice of Floor Heave Mechanism and Prevention Measures

为了避免或减轻深部开采过程中巷道底鼓对生产的影响,分析了诱发巷道产生底鼓的原因,并提出相应防治底鼓的方法。结合开滦范各庄矿4171工作面风道掘进后产生的底鼓现象进行分析并提出相应控制对策。实践表明:采取相应对策后,4171风道底鼓得以有效控制,验证了防治底鼓对策的合理性和可行性。

In order to avoid or reduce the process of deep mining roadway floor heave effect on production, the causes of floor heave of roadway induced was analyzed, and corresponding methods for the prevention and control of floor heave were put forward. Combined with Fangezhuang Mine 4171 working face excavation, based on the analysis of the bass drum, the corresponding control were put forward. Practice showed： after taking corresponding effectively got control of floor heave of 4171 air duct. The technology validated the rationality and feasibility of the prevention and control of floor heave
