Detailed ways

The embodiment of the utility model provides a mine monitoring and early warning device, which solves the technical problem in the prior art that the monitoring of the safety status of the mine needs manpower, and then realizes the effective monitoring of the safety status of the mine.

In order to solve the above-mentioned technical problem in the prior art that monitoring the safety status of mines requires manpower, the above-mentioned technical solutions will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The utility model embodiment provides a mine monitoring and early warning device, as shown in Figure 1, including: a stress sensor 101, a ground sound sensor 102, a temperature sensor 103, a vibration sensor 104, a water sensor 105 and a gas sensor 106, and also includes connecting each The signal conditioner 107 at the output end of the sensor, the output end of the signal conditioner 107 is connected to the controller 108 , and the controller 108 is connected to the alarm 109 , the display 110 , the crane 111 , the water pump 112 and the fan 113 .

In a specific embodiment, when any sensor in the stress sensor 101, the ground sound sensor 102, the temperature sensor 103, the vibration sensor 104, the water sensor 105 and the gas sensor 106 detects that the signal is abnormal, it is controlled by the controller 108. The alarm 109 reports to the police, so that the staff of the mine can know in time that there is a dangerous situation in the mine. When the vibration sensor 104 detects that there is vibration, the crane 111 is controlled by the controller 108 to quickly rescue the staff in the besieged mine; Turn on the water pump 112 to pump out the water; when the gas sensor 106 transmits the detected gas data to the controller 108, and the controller 108 judges that the gas data exceeds the preset gas value, it controls to turn on the fan 113 to disperse the gas to prevent the gas concentration from increasing. Dangers caused by too high.

The above-mentioned stress sensor 101 uses strain gauges to convert non-electrical physical quantities such as displacement, force, pressure, acceleration, and torque into sensors for changes in resistance value, which can monitor the stress of mine rocks, and collect stress data according to different mining progress and time. And transmit it to the display 110 through the controller 108 for display. It enables the monitoring personnel to know the current stress state of the mine rock.

The geoacoustic sensor 102 can detect the change of acoustic emission and microseismic when the structure of the mine rock is about to lose stability. A large amount of research data shows that before the rock engineering structure is damaged, it must release the accumulated energy in the form of sound for a period of time. The intensity of this energy release changes as the structure approaches instability. The rich information of the internal state change of the mine rock, processing and analyzing the received signal can be used as the basis for evaluating the stability of the mine rock, so that the ground acoustic sensor 102 can use the characteristics of the acoustic emission and microseismic of the mine rock to detect the mine rock. The stability of the rock mass is monitored, so as to predict rock collapse, roof fall, slab, landslide and rockburst and other ground pressure phenomena.

The mine-used temperature sensor 103 is used to measure the ambient temperature in the mine, so as to detect fire hazards in time. The temperature measured by the temperature sensor 103 is displayed on the display 110 .

The function of each sensor is introduced above, and a signal conditioner 107 is correspondingly provided for each sensor, and the function of the signal conditioner 107 is to compensate the error of the sensor at different temperatures.

Specifically, each sensor is respectively provided with a clock controller, which can be set to collect data at fixed periodic intervals. In this way, not only can energy be saved, but at the same time, data can be collected reasonably without causing a large amount of data to be sent to the controller 108. The phenomenon that the amount of data is too large to handle.

On the other hand, the mine monitoring and early warning device is also provided with a sensor group 114 for collecting mine environment data, a wireless transmitter 115, and a monitoring host 116. The sensor group 114 for collecting mine environment data is connected to the controller 108, and the controller 108 is connected to The wireless transmitter 115 and the monitoring host 116 are wirelessly connected to the wireless transmitter 115, wherein the sensor group 114 for collecting mine environmental data specifically includes: a PM2.5 sensor, a humidity sensor and a soil pH detection sensor. By detecting the value of environmental parameters around the mine, including: PM2.5 value, humidity value, and surrounding soil pH value, it can be judged whether the surrounding environment is in good condition, and when the monitoring environment is poor, the mining work will be stopped.

The data is detected by each sensor in the mine monitoring and early warning device, and is analyzed and processed by the controller 108 . The technical effect of effectively monitoring the safety status of the mine is realized.
