摘要
工作面防治水是地测防治水的一项关键工作,需要结合煤矿井下地质特征对工作面防治水进行针对性改进。以A矿为例,该矿因受导水裂隙带影响,存在基于离层水的涌水风险。基于此,首先对该矿区地质和水文地质进行了概述,明确了充水水源、充水通道和充水强度等充水条件;其次应用解析法对1311、 2307工作面的正常涌水量及最大涌水量进行了计算分析,并开展了涌水量实时监测工作;最后从“探、防、堵、疏、排、截、监”方面提出复杂水文地质条件下离层水的防治策略。经实践应用,所提出的防治水策略可以降低水害影响。
Water control in working faces is a key task in geological survey and water control work,which requires targeted improvement based on the underground geological characteristics of coal mines.Taking A Mine as an example,due to the influence of water-conducting fracture zones,there was a risk of water inflow caused by separation layer water.Based on this,firstly,the geology and hydrogeology of the mining area were summarized,and the water-filling conditions such as water-filling sources,water-filling channels and water-filling intensity were clarified.Secondly,the analytical method was used to calculate and analyze the normal water inflow and maximum water inflow in the 1311 and 2307 working faces,and real-time monitoring of water inflow was carried out.Finally,water control strategies for separation layer water under complex hydrogeological conditions were proposed from the aspects of"exploration,prevention,blocking,drainage,discharge,interception and monitoring".Through practical application,the proposed water control strategies can reduce the impact of water hazards.
