| 摘 要： | 基于第四系冲积层水位下降是井筒破裂的主要因素之一,以济宁三号煤矿为例,分析工广周边第四系水源井取水活动对煤矿主井、副井和风井井筒稳定性的影响。根据水源井取水层位不同对水源井分类,结合第四系冲积层水位观测孔观测结果,研究了不同取水层位水源井取水对含水层水位的影响。结果表明:工广周边地面水源井取水会引起相应含水层的水位下降,但对工广区含水层水位下降影响有限;第四系含水层水源井取水对井筒稳定性有影响,但影响不大。

| Abstract: | Based on quaternary system alluvium water level drop is one of the main factors of shaft damage.Take Ji Ning No.3 coal mine for example.The effect on Main shaft,auxiliary shaft and air shaft stability after getting water from quaternary system alluvium water source well aroung industrial square was analysed.According to the difference of the depth of getting water,classifying the sections of getting water.By means of observing the water level of apertures,the effect on shaft damage after getting water from surface loose aquifer water source well was studied.The results show that getting water from water source well can lead to the decline of water level,but is limited to the water level drop.Getting water from quaternary system alluvium water source well aroung industrial square has an effect on shaft stability,but is not enormous. |
