Problems solved by technology

This is an operational inconvenience
In addition, under ideal circumstances, even if acoustic emission and microseismic technology provide early warning of potential rockbursts, it is not convenient to locate the risk area and quantify its severity, which is not conducive to preventive treatment

Embodiment 1

[0060] On the basis of the above structure, in this embodiment, the bottom box 1 is equipped with a pan-tilt 2, and the pan-tilt 2 is fixed and installed on the bottom box 1 by bolts, the structure is simple, easy to disassemble and assemble, saving time and effort; the lighting mechanism and infrared The temperature measuring mechanism is fixedly installed on the cloud platform 2 by bolts respectively. During the monitoring process, the infrared temperature measuring mechanism is driven to rotate by the pan-tilt 2, thereby monitoring the rock temperature of multiple monitoring units in the target area successively, the structure is simple, and the measurement is convenient and quick.

[0061] Preferably, the lighting mechanism is preferably fixedly installed on the infrared temperature measuring mechanism, so as to better cooperate with it and improve the lighting effect (such as Figure 4 and Figure 5 shown).

Embodiment 2

[0063] On the basis of Embodiment 1, in this embodiment, a transparent protective cover 3 is fixedly installed on the bottom box 1, and the protective cover 3 is fixed on the bottom box 1 by means that those skilled in the art can think of, such as welding or bolts connection; the cloud platform 2, the lighting mechanism and the infrared temperature measuring mechanism are located in the protective cover 3. During the monitoring process, the protective cover 3 is used to protect the pan-tilt 2 and the infrared temperature measuring mechanism to prevent rain and dust from affecting the performance of the infrared temperature-measuring mechanism and the pan-tilt 2, and to ensure the normal operation of the equipment.

Embodiment 3

[0065] On the basis of the second embodiment, in this embodiment, a transparent shell 4 is fixedly installed on the bottom box 1 , and the shell 4 is covered outside the protective cover 3 and formed integrally with the bottom box 1 . The working performance of the pan / tilt 2 and the infrared temperature measuring mechanism is further protected by the shell 4, so as to ensure the normal operation of the equipment.

[0066] In addition to the above structure, the housing 4 can also be made of opaque material. At this time, the side wall of the housing 4 is provided with a through opening matching the rotation track of the infrared temperature measuring mechanism.

Abstract

The invention relates to a rockburst infrared monitoring method which specifically comprises the following steps: dividing a target area to be monitored into a plurality of monitoring units, and numbering the monitoring units; gradually detecting the temperature of the rock in the plurality of monitoring units to obtain a change trend chart of the rock temperature; determining the normal rock temperature in the target area according to the obtained rock temperature change trend chart; judging and analyzing whether the rock temperature in the plurality of monitoring units is abnormal or not according to the obtained normal rock temperature; the invention further provides a rockburst infrared monitoring device which comprises a bottom box, an infrared temperature measuring mechanism and a lighting mechanism, and the infrared temperature measuring mechanism is rotatably installed on the bottom box and used for measuring the temperature of rock; the lighting mechanism is fixedly installedon the holder. The method has the advantages that the potential rockburst area in the roadway can be accurately positioned, the rockburst phenomenon can be monitored and warned more accurately, warning is conducted in time, the safety of roadway constructors and equipment is improved, the accuracy is higher, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of mine safety, in particular to an infrared monitoring device and method for rockbursts. Background technique [0002] In mining, traffic construction and hydropower projects, it is often necessary to work in roadways. Brittle rocks often appear in roadways. Because of the excavation of the roadway, the original three-dimensional equilibrium force situation of the brittle rock was broken, and the brittle rock was subjected to an unbalanced stress instead. After this stress gathers, it causes the brittle rocks in the roadway to scatter explosively, which is the phenomenon of rockburst. Rockburst generally occurs under high ground stress conditions. During the excavation process of underground engineering, the stress redistribution of hard and brittle surrounding rocks due to excavation leads to stress concentration in local surrounding rocks, and the sudden release of elastic strain energy stored in surrounding rock...
