摘　　要：为深入分析底板导水通道的演化形成过程及承压水导升规律,自主研制了底板承压水导升监测系统,该系统由承压水加载系统、承压水导升系统组成。试验结果表明:承压水导升监测系统不仅可以较为精准地模拟含水层对底板岩体的力学作用,而且可直观地再现底板不同位置处承压水的导升情况;当采动压力峰值经过导升管所处位置后往往会造成该处水流量增加,并伴随底板岩体应力不断释放,承压水导升高度也随之增加,底板岩体卸荷程度与监测管出水量同步达到峰值。In order to analyze the evolution process of the floor water channel and the law of confined water upflowing, the monitoring system for the floor confined water upflowing is developed independently. The system is composed of the loading system and the upflowing system of the confined water. The test results have shown that the monitoring system can not only accurately simulate the mechanical action of the aquifer on the floor rock, but also directly reproduce the confined water upflowing at different positions of the floor. When the peak of mining pressure passes through the position of the upflowing pipe, the water flow rate will often increase. At the same time, the upflowing height of the confined water will increase as the stress of floor rock is continuously released. The uploading degree of the floor rock reaches the peak value synchronously with the water output from the monitoring pipe.
