龙泉矿4301工作面涌水原因及水害治理研究

Study on the Causes of Water Inrush in the 4301 Working Face and the Treatment of Water Disaster

为了治理龙泉矿4301工作面回采过程中底板出水问题,确保工作面能够进行安全回采,通过对龙泉矿4号煤开采时的水文地质条件进行简要分析,对涌水水源、水质以及奥灰水水位进行研究分析。对工作面使用井上下两种物探手段,查明了工作面涌水的具体原因及出水通道,制定了详细的工作面底板水害治理方案。

In order to solve the problem of floor water outflow in the mining process of 4301 working face of Longquan Mine and ensure the safe mining of the working face,the hydrogeological conditions during the mining of No.4 coal in Longquan Mine are analyzed briefly,the water source,water quality and the water level of Ordovician limestone water are studied and analyzed.Two kinds of geophysical exploration methods are used in the working face,the specific reason of water inrush and the outlet channel are found out,and the detailed treatment scheme of water disaster in the working face floor is formulated.
