摘要
矿坑涌水量的大小受到多种因素的共同制约,找出起主导作用的影响因素是评价矿坑涌水量大小的关键。通过分析长安金矿长安矿段近年来矿山建设中不同中段的长观资料,对涌水量与降雨量进行对比,认为大气降雨是长安金矿长安矿段矿床充水的主要影响因素,矿坑涌水量随着井巷深度的增加,降雨对矿坑的涌水量的影响呈几何倍递减趋势,且降雨对涌水量的影响存在30~50天的滞后性。
The amount of mine water inflow is restricted by many factors.The leading influencing factors is the key to evaluate the amount of mine water inflow.By analyzing the long-term data of different middle sections of Chang'an Gold mine construction in recent years and comparing the water inflow and rainfall,it is concluded that atmospheric rainfall is the main factor affecting the water inflow of Chang'an Gold mine.With the increase of the depth of the shaft,the influence of rainfall on the water inflow of the mine shows a geometrically decreasing trend.The effect of rainfall on water inflow has a lag of 30-50 days.
