矿坑充水的形成及影响因素分析

Analysis of Formation and Influencing Factors of Pit Filling Water

当前,我国矿山数量逐年攀升,相应的采矿技术水平也在新时代科技的辅助之下得到了提高。但在实际应用过程中,总会出现一些突发性的问题,尤其是矿坑充水问题,常常给矿山施工带来不便。因此,对矿坑充水的形成及影响因素做出分析与研究极为重要。本次结合矿区实例简要分析矿坑充水的安全隐患,并对矿坑充水形成条件进行研究,对径流循环、充水通道多变以及突水特征不明显进行矿坑充水影响因素的探析。最终的实例分析表明:在相同的测试环境之下,D矿区的含水层涌向矿坑的水得到了控制,这主要是由于加强了对含水层采厚深度的控制,以此来进一步划定、堵塞充水的相关通道,采深越大,堵塞效果越好,地层水以及地下水向矿坑反水的概率越低,可以进一步降低矿坑充水发生的概率,确保工程顺利实施。最后提出三点预防措施。

By analysis of the hidden danger of pit filling water,the paper probes into the formation condition and influencing factors of pit filling water from aspects of runoff circulation,variable filling water passages and obscure water inrush characteristics,whose example analysis shows that water inflow from the aquifer of D mining area can be controlled due to the reinforcement of mining height and depth control;the greater the mining depth is,the better the blocking effect;and the occurrence probability of pit filling water can be reduced with little reverse flow of formation and ground water to the pit to guarantee the smooth construction accomplishment,and finally proposes three preventive measures.
