Description

TECHNICAL FIELD

[0002] In the field of coal mining safety, microseismic monitoring is the core means for preventing dynamic disasters such as rock burst, which captures mine microseismic signals in real time through a microseismic network, determines microseismic events in combination with the location of the seismic source and the recording of the occurrence time, synchronously calculates the energy of the events, analyzes the occurrence law of mine dynamic disasters by means of the strength, frequency and spatial distribution characteristics of microseismic activity, and finally realizes disaster risk assessment and early warning, which plays an irreplaceable role in ensuring the effectiveness of coal mine rock burst prevention monitoring and deepening the study of rock burst occurrence law. The current microseismic monitoring installation technology adopts a deep hole deployment method, which mainly drills a deep hole in the surrounding rock, sends the microseismic probe into the deep part of the drill hole, and fills the drill hole with resin anchoring agent, cement mortar and other media to make the probe tightly coupled with the surrounding rock, so as to ensure the sensitivity and accuracy of signal acquisition. This installation technology can effectively capture deep surrounding rock microseismic activity and the monitoring effect has been recognized by the industry. However, the deep hole microseismic probe needs to be sent into the monitoring area as a one-time consumable. As the coal mining face advances, new probes need to be continuously installed, and the old probes that have entered the goaf cannot be recovered, resulting in a large amount of equipment waste and a significant increase in monitoring economic costs. At the same time, once the probe fails in the drill hole, it cannot be repaired or replaced due to the installation method, which easily leads to local monitoring interruption, affecting the continuity and integrity of the microseismic data, and further reducing the reliability of disaster warning.
