红岩煤矿井下主要突水点与地表多以岩溶管道连通，因此对降雨具有暴涨暴落式快速响应特征。本文运用时间序列分析频谱方法定量研究了井下南茅口突水点涌水量与海孔河流量之间的关系，结果表明两者均有三个明显的周期峰，分别为２５６天、７３天和１８天，相对应于这三个周期峰，突水点涌水量对河流量的滞后期分别为５天、３天和１天 The main water inrush point in Hongyan coal mine is mostly connected with the karst pipelines on the surface of the earth. Therefore, it has the characteristics of rapid and violent rapid response to rainfall. In this paper, the relationship between the water inflow at the South Maokou water bursting point and the pore water flow was quantitatively studied by using the time series analysis spectrum method. The results show that there are three obvious periodic peaks, 256 days, 73 days and 18 Day, corresponding to these three periods, the stagnant periods of water inrush in water inrush point are respectively 5 days, 3 days and 1 day
