摘 要:为研究矿井老空区积水规律,分析半充填工作面采空区充水系数等,对仰采工作面连通性采空区积水充水因素、涌水量、积水量进行了分析、总结,对半充填工作面采空区充水系数进行了反算。通过分析研究,对比分析仰采工作面采空区积水是否存在其他水源补给,可研判是否存在水害风险,可以根据半充填工作面经验充水系数计算预计其他充填工作面采空区积水量。In order to study the regularity of water accumulation in the old goaf of the mine and analyze the waterfilling coefficient of the goaf in the semifilling working face,the factors of waterfilling,water inflow,and water accumulation in the connected goaf of the overhead mining face were analyzed and summarized,and the waterfilling coefficient of the goaf in the semifilling working face was backcalculated.Through analysis and research,comparative analysis can be conducted to determine whether there are other sources of water supply for the accumulated water in the goaf of the overhead mining face,and to determine whether there is a risk of water damage.The estimated amount of accumulated water in the goaf of otherfilling working faces can be calculated based on the empirical waterfilling coefficient of the semifilling working face.
关 键 词:半充填工作面 老空水 充水因素 充水水源 充水系数
