Description

Technical Field

[0001] The invention belongs to the technical field of mining engineering, and in particular relates to a coal mine rock burst monitoring device and a monitoring method. Background Art

[0002] In recent years, with the gradual deepening of coal mining depth, the impact of rock burst has also become increasingly severe, which has brought great harm to coal mine safety production. The occurrence of rock burst is relatively complex, and it is difficult to solve practical problems with simple mathematical analysis and rock mechanics theory. Because the coal-rock layer is affected by geological structures such as joints, fissures and faults, the coal-rock layer exhibits discontinuous and anisotropic characteristics. In addition, water and gas in the coal-rock layer act together with the original rock stress and tectonic stress on the coal-rock layer, making the physical and mechanical properties of the coal-rock layer more complex and constantly changing in time and space. With the deepening of mining, in different locations, the choice of artificial methods has formed the changing characteristics of coal-rock layers under different conditions. The diversity and complexity of its changes have brought development to the monitoring and early warning technology of rock burst in coal mining. According to the survey results of the current rock burst mines in my country, the technologies used for rock burst monitoring and early warning mainly include drilling cuttings method, electromagnetic radiation method, coal body stress method, geoacoustic monitoring and microseismic monitoring.

[0003] However, the coal mine rock burst warning devices currently on the market are less portable and inconvenient to move, and it is difficult to combine the electromagnetic radiation method with the coal body stress method. In addition, the borehole stress gauges used in the existing warning devices have long connecting wires during use, which are troublesome to comb and may even become tangled, affecting work efficiency. In addition, the existing borehole stress gauges cannot fully fit the borehole wall, making it difficult to accurately and timely reflect changes in mine pressure, and cannot achieve the effect of fixed installation in the borehole for continuous monitoring of mine pressure.
