[0015] To make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the utility model are only based on the drawings of the utility model, and they do not specifically limit the utility model.

[0016] A coal and rock dynamic disaster monitoring and early warning device, as Figure 1 and Figure 2 shown, includes an installation column 1, a base 2, a clamping frame 3, a mounting plate 4, a charge probe 5 and an elastic sheet 6, an alarm lamp 7 and a loudspeaker 8, a data line 9, a data analyzer 10, a monitoring host 11 and an alarm 12. The lower side of the installation column 1 is connected to the base 2. Six installation holes are opened on the base 2 for easy installation. The outer side of the clamping frame 3 is an arc structure for easy clamping of the charge probe 5. Two clamping frames 3, one above the other, are connected to the lower part of the installation column 1. The upper side of the installation column 1 is connected to the mounting plate 4. Six charge probes 5 are clamped between the clamping frames 3. Three elastic sheets 6 are connected to the outer sides of the charge probes 5. Loudspeakers 8 are connected to the upper parts of the charge probes 5. Alarm lamps 7 are connected to the upper sides of the charge probes 5. The monitoring host 11 is installed on the upper part of the mounting plate 4. Data lines 9 are connected between the charge probes 5 and the monitoring main frame, and data analyzers 10 are installed on the data lines 9. The alarm 12 is connected to the upper side of the monitoring host 11.

[0017] When using the present utility model, first move the mounting column 1 to the coal mining face in the coal mine, and then install the mounting column 1 in the working area through the cooperation of the mounting holes on the mounting base 2 and bolts. After drilling the monitoring position on the coal mining face, remove the charge probe 5 from the rack, and then place the charge probe 5 inside the drilled hole. Under the action of the elastic piece 6, the charge probe 5 is fixed inside the drilled hole, so that the charge probe 5 monitors the charge signals in the coal and rock strata. The monitored signals are transmitted through the data line 9 to the data analyzer 10 for processing, and then transmitted to the monitoring host 11 for calculation. The coal and rock dynamic disasters are predicted by summarizing each data. When it is predicted that a coal and rock dynamic disaster may occur, control the alarm 12 to start alarming. When a coal and rock dynamic disaster occurs, there is coal and rock rupture, and charges are generated during the deformation and rupture process of the coal and rock mass, causing the charge amplitude of the charge probe 5 to rise sharply or fluctuate sharply. As a result, the charge probe 5 controls the alarm lamp 7 to flash, and at the same time alarms through the speaker 8 to alert the nearby staff, thus playing the role of being convenient for installation, improving the installation efficiency, enhancing the environmental adaptability of the equipment, and being able to be quickly deployed and efficiently monitored.
