中文摘要：

为研究带压开采工作面底板破坏规律和突水形成机制，以焦作矿区赵固一矿首采工作面底板为研究对象，使用自主设计的底板突水机理物理模拟试验系统进行相似模拟试验。通过对回采过程中底板突水过程以及突水前后岩层的视电阻率进行模拟和观测，研究了承压含水层威胁下底板破坏和发生突水的一般规律，揭示了矿山压力引发的破裂构造是导致底板突水的重要因素，并得出底板破坏深度。研究结果可为评价赵固一矿带压开采提供理论基础，为揭示带压开采底板突水的力学机制提供参考。

英文摘要：

: In order to study breakage law of working face floor in coal mining above aquifer and formation mechanism of water inrush, taking the first working face floor from Zhaogu No. 1 coal mine in Jiaozuo mine as the research object, the similar simulation test is carried out by the self-designed water inrush mechanism of floor physical simulation test system. By means of water inrush process from floor during the mining, performs simulation and observation to apparent resistivity of each rock stratum before and after water inrush, the general law of breakage and water inrush disasters of working face floor under mining above aquifer are studied. It revealsthe rupture structures caused by underground pressure is one of the important factors for water inrush from floor,and the failure depth of working face floor is obtained. The research results can provide theoretical basis for evaluation of mining above aquifer in Zhaogu No. 1 coal mine,and offer references to the mechanical mechanism of water inrush from floor.
