【摘要】 钻孔冲洗液简易水文观测分析法和钻孔压、注水实验法等传统覆岩破坏参数检测方法难度大、成本高、精度不高。介绍一种利用网络并行电法仪、矿井以太网、地面远程终端组成工作面覆岩破坏参数动态监测系统。给出了详细的系统组成结构和井下采集部分的布设方式。系统可随采掘工作推进记录覆岩破坏的动态发育过程。以应用实测数据为基础,分析给出了覆岩破坏参数,对矿井安全生产具有重要的指导意义。更多还原

【Abstract】 The traditional detection methods for the overburden failure parameter are difficult,high cost and low precision,such as simple hydrological drilling fluid analysis,drilling pressure and water injection experiment.A new dynamic monitoring system of overburden failure parameter in working face using network parallel electrical instrument,mine ethernet and ground remote terminal is introduced.The detailed system composing configuration and the layout method of underground sampling section are given.On the basis of experimental data obtained from practical application,the overburden failure parameter is provided.The system can record the dynamic development process of overburden failure with mining,and it has guiding significance on safety production in coal mine.更多还原
