为了解决煤矿微震监测孔中检波器问题,研制了一种使用电磁式超级动圈检波器的自动推靠孔中检波器,该检波器使用H电桥控制检波器推靠和回收,能自动监测工作电流,电流过大自动断电保护,使孔中检波器工作稳定可靠。通过性能对比测试,证明该孔中检波器性能良好,满足了微震监测系统孔中监测的需求。 In order to solve the geophone problem in microseismic monitoring boreholes in coal mines, an automatic push-in-geophone detector using electromagnetic super-dynamic detector was developed. The geophone uses H-bridge to control the geophone to push and recover and can automatically monitor Working current, the current is too large automatic power-off protection, so that the hole detector work stable and reliable. Through the performance comparison test, it is proved that the detector in the hole has good performance and meets the requirement of monitoring in the microseismic monitoring system hole.
