辛置矿井涌水特征及影响因素分析

Analysis on Waterflow Characteristics and Impact Factors in Xinzhi Coal Mine

随着矿井开采深度不断增加,各种因素恶化并威胁着矿井安全生产,尤其是矿井涌水。以辛置矿为工程背景,通过应用涌水量统计数据,分析了该矿区540水平、310水平、东四1#水仓以及450水平的涌水动态特征和水质特征,确定了影响矿井涌水的3个主要因素:含水层的富水性、矿井构造条件和老空水。

With the deepening of underground mining,various factors become unfavorable to a degree that may pose threat to the safe production of mines,especially water related hazard.Taking Xin Zhi mine as the engineering background,through the statistics of water inflow data,the dynamic analysis are carried out on water influx and quality characteristics with the support of statistic data at the level of-540 m,-310 m,-450 m from the surface,and No.1 water sump in East 4 tunnel,respectively.Three main factors affecting the water influx are determined,namely,Productive aquifer,strata condition and goaf condition.
