针对煤矿井下地震勘探技术发展缓慢的问题,基于槽波地震探测技术,采用第三代节点式地震仪的设计理念,开发出"节点式设计、独立型激发、分布式采集、三通道存储、集中式回收"的新型槽波地震仪,实现了煤矿井下槽波地震观测系统的灵活、无约束、自由布设,且整个采集系统无主机、无大线、无需通信、可同步采集等,施工高效、快捷,满足了煤矿井下超长超宽工作面、互不贯通的巷道之间以及采区、盘区和跨层条件下的槽波地震探测的需求。

According to a slow development problem of the mine seismic exploration technology,based on the channel wave seismic exploration technology,a design C onception of the third generation node type seismograph was applied to develop a new type channel wave seismograph with“a node type design,independent excitation,dis tributed acquisition,three channel storage and centralized recovery" .A flexible,unconstrained and free layout of the undergroud mine channel wave seismic observation syst em could be realized.The completed acquisition system with no host computer,no cable,no communication,synchronous acquisition and other advantages and with a high a nd rapid construction could meet the requirements of the channel wave seismic exploration under the overlong and over wide mining face,no connection between the gatew ays as well as the mining block,mining panel and crossed layers condition.
