摘要
为了研究煤层开采中的流固耦合问题,在"固-液-气"三相模拟实验台的基础上进一步完善了流固耦合模拟实验平台的应力、位移、渗流测试系统及测试技术。针对富水风积沙层下采煤进行了模拟,实验中的矿压显现规律和潜水渗流规律与实际相吻合,证明了实验过程可信、结论可靠。实验设备和技术的完善突破了传统的单一固体模拟,为地下工程中流固耦合相似模拟实验取得了新进展。
In order to study the coupling equation in mining,On the basis of experiment plant of ＂solid-liquid-gas＂ the stress testing system,displacement testing system,interstitial flow testing system and technological development have been finished.Trough the mining in shallow coal seams underlying in desert with rich water experiment,the reliability of experiment is proved by the consistency of weighting law and seepage law between simulation materials experiment and field observation.The research of this experiment plant and experiment technology have made a breakthrough at single solid simulation experiment and made a great progress at protection water mining study by simulation experiment.
