4) bottom aquifer
底部含水层
1.
Through the analysis of engineering geology and hydrological geology in Yanzhou minei,t is found that the main reason for shaft damage is the compression of bottom aquifer and there is a law between head loss of bottom aquifer and shaft lining damage.
通过对兖州矿区的工程地质水文地质的分析可知,立井井筒破坏的主要原因为井筒周围底部含水层的压缩,且含水层水头的降低与立井井筒的破坏直接存在一定的规律,底部含水层的压缩在立井井筒内产生附加应力,此附加应力造成立井井筒的变形破坏,通过拉格朗日法对立井井筒的破坏过程进行数值模拟,通过计算得到立井井筒破坏过程中各个影响因素的变化规律,从而得到立井井筒的破坏规律,为兖州矿区立井井筒破坏的治理提供理论基础,而且在立井井筒的破坏机制分析及防治方面发挥重要的作用。
