The invention discloses a monitoring device for microseism impending earthquake infrasonic waves and a usage method thereof. The device comprises an infrasonic wave receiving device, a transmission tube, a current converter, an oscilloscope, an isolation cover, a filter ring, a wave focusing plate, a sealing ring, an amplification ring, a sealing rubber tube, a fixed plate, a closed protective tube, a glass tube, infrasonic waves, a base, a monitor, an adjustment knob and a loudspeaker. The beneficial effects of the present invention are that the monitoring device adopts glass tube transmission to receive and collect infrasonic waves; the transmission loss of the infrasonic waves is lowered through transmission refraction of the infrasonic waves in the glass tube; the precision of the infrasonic wave transmission is ensured; a current converter of the monitoring device adopts a taper design which can further amplify the transmitted infrasonic waves to ensure that even weak vibration can be known in advance and to ensure safety of usage; and the monitoring device is convenient to operate, and is firm, durable, stable and sturdy. Components are flexible in connection.
Description
technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device for microseismic imminent earthquake infrasonic waves and a method for using it, belonging to the technical field of microseismic monitoring applications. Background technique [0002] As people continue to mine underground mines, microseismic is a natural condition that is often encountered in the mining process. Microseismic is a small earthquake that occurs during the deep mining of underground mines. Rock rupture and seismic activity are often impossible. phenomenon to avoid. Mining-induced seismicity is generally defined as those seismic events caused by changes in the stress field in the rock mass near the mining tunnel that lead to rock failure. The total stress state around the mining tunnel. It is the sum of the additional stress caused by mining and the environmental stress in the rock body. The infrasound wave is a kind of wave generated before the micro-se...
