针对煤矿顶板灾害多发及人工监测不及时问题,设计了一种煤矿顶板动态在线监测系统;详细介绍了该监测系统的技术原理、组成结构、功能模块及应用效益。实际应用表明,该系统实现了顶板压力、位移、应力监测数据之间的融合和可视化分析,可对煤矿顶板安全隐患进行快速、准确的预警、预报。 Aiming at the problem of frequent roof disaster and manual monitoring in coal mine, a dynamic on-line monitoring system for coal mine roof was designed. The technical principle, compositional structure, functional modules and application benefits of the monitoring system were introduced in detail. The practical application shows that the system realizes the fusion and visual analysis of roof pressure, displacement and stress monitoring data, and can quickly and accurately predict the potential safety hazards of coal mine roof.
