Abstract: In order to improve the triggering system of cable-connected channel-wave earthquakes, based on the actual situation that the new detonation equipment in coal mines does not match the pulse triggering unit, resulting in the inability to carry out channel-wave earthquakes, a triggering system with the vibration circuit triggering mode as the core is proposed. The vibration loop triggering system includes multiple improved processes such as the vibration circuit triggering detection network, multi-sensitivity vibration switch, and quasi-synchronous triggering method. The principle is that during data collection, a detection network composed of vibration loop triggers and channel wave equipment is arranged in the roadway. The vibration loop triggers are fixedly installed on the roadway side or support body near the excitation shot point, and the appropriate sensitivity of the vibration loop triggers is set according to the on-site construction environment. When the digital electronic detonator detonates the explosive inside the shot point, the seismic wave propagates in the coal seam, and the trigger device of vibration loop will vibrate near the firing point. The copper ball collides with the copper outer tube in the vibration switch, and collision contact forms a current loop. The trigger device of vibration loop is triggered immediately, the output state changes, and the linked signal transmitter guides the seismic equipment to synchronously start data acquisition. The results show that the system adopts the trigger mode of vibration loop instead of the pulse trigger mode, which solves the problem about the channel wave earthquake can not work normally after the replacement of digital electronic detonator and other new detonating equipment in coal mine. The multi-sensitivity vibration switch has high, medium and low sensitivity. It can support the vibration triggering in various complex environments and improve the applicability and practicability. The vibration switch is installed and connected in vertical and horizontal groups to ensure that the vibration switch can enter the vibration triggering state in multiple loops after the vibration occurs, and improve the success rate and completion rate of the vibration triggering. In the trigger method of class synchronous, the trigger device of vibration loop is installed close to the firing point, and the starting delay is very short, eliminated the effect of uncertain delay error about detonator, forms the trigger effect of class synchronous, reduces the delay error, and realizes the accurate triggering of the channel wave earthquake.
