Example Embodiment

[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0022] See figure 1 , The underground microseismic monitoring system of the metal mine of the present invention includes a microseismic signal collection device 1, an underground network multi-channel collector 2, a transmission local area network 3, a hub local area network 4, and a ground data receiving and processing platform 5.

[0023] There is at least one downhole network multi-channel collector 2. In this embodiment, there are three downhole network multi-channel collectors 2, all of which are set in the tunnel of the monitored section of the underground. The downhole network multi-channel collector 2 includes 16 differential input channels for analog signal acquisition, and each differential input channel is connected to a microseismic signal collection device 1 respectively, and each microseismic signal collection device 1 is fixedly distribut...

Abstract

The invention discloses a metal mine downhole microseismic monitoring system which comprises at least one downhole network multi-channel collector arranged in a roadway of a downhole monitored section. Every downhole network multi-channel collector comprises a plurality of difference input channels for analog signal collection, every difference input channel is respectively connected with a microseismic signal collecting device, every microseismic signal collecting device is fixedly distributed on downhole roadway side walls in different directions, and output ends of the downhole network multi-channel collectors are connected with a ground data receiving processing platform sequentially through a transmission local area network and a concentrator local area network. The metal mine downhole microseismic monitoring system has the advantages of performing microseismic real-time on-line monitoring and analysis, preventing downhole accidents, optimizing blasting and ore falling effect in the recovery process and mastering vibration conditions of surrounding device systems and the like and is suitable for being widely applied to the technical field of microseismic monitoring.

Description

technical field [0001] The invention relates to the technical field of microseismic monitoring, in particular to an underground microseismic monitoring system for metal mines. Background technique [0002] With the continuous underground mining of metal mine production, the rock mass pressure on the deepening production roadway is gradually deepening, which easily leads to underground geological disasters such as mining roadway roof collapse, water inrush and flooding, and rock burst. At the same time, it has become an urgent problem to be solved in the production of metal mines to analyze, judge and sort out the waveform of normal mining blasting and rocking in order to optimize the effect of blasting and rocking in the mining process and to grasp the vibration status of surrounding equipment systems. Microseismic monitoring technology is currently a commonly used rock mass engineering safety monitoring technology at home and abroad, and is widely used in rock mass safety p...
