Traditional mine gas monitoring methods mainly rely on manual on-foot carrying a variety of observation, detection, monitoring and sampling instruments to the target location for on-site operation. However, this method has many shortcomings.

[0003] First, the mine environment is often complex and harsh, and the routes are remote, which poses a great challenge to the safety of personnel walking. At the same time, manual operation of multiple instruments on site is not only labor-intensive, but also relatively inefficient; and the mine environment is complex and harsh, and manual operation on foot poses a great safety hazard. Once an accident occurs, it will pose a serious threat to the life safety of the staff.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1 and Figure 2 As shown, the present invention provides an integrated multi-gas monitoring device for mining, including a protective shell 110, which is installed on the mine sealing wall, the working face corner and / or the excavation head; an exhaust chamber and a multi-gas monitoring chamber arranged on one side of the exhaust chamber are arranged in the protective shell 110, and a multi-gas monitoring alarm 121 is arranged in the multi-gas monitoring chamber. A through hole is arranged on the protective shell 110 below the multi-gas monitoring alarm 121, and the multi-gas monitoring alarm 121 is connected to the air outside the goaf at the mine sealing wall, the working face corner and / or the excavation head through a first gas pipeline 123 passing through the through hole. A plurality of exhaust pumps 131 are arranged in the exhaust chamber, one end of the exhaust pump 131 is connected to the goaf through an exhaust pipeline 132, and the other end of the exhaust pump 131 is connected to the goaf through a second gas pipeline 133. To the first gas pipeline 123, an electric rotating baffle 135 is arranged at the connection between the first gas pipeline 123 and the second gas pipeline 133; a video monitoring room is arranged on the side of the multi-gas monitoring room away from the exhaust chamber, and a camera 141 and a video display screen 142 including a video processor are arranged in the video monitoring room, the camera 141 is connected to the video processor, and the electric rotating baffle 135, the multi-gas monitoring alarm 121, the video processor and the exhaust pump 131 are all connected to the ground monitoring room 160 through a communication module; when in use, according to monitoring requirements, the electric rotating baffle 135 is controlled to block the second gas pipeline 133 from connecting with the multi-gas monitoring alarm 121, or the exhaust pump 131 is controlled to start and the electric rotating baffle 135 is controlled to block the air outside the goaf from connecting with the multi-gas monitoring alarm 121.

[0029] Specifically, the communication module includes an underground intrinsically safe switch 151 installed in the mine, an aboveground switch 153 set above the mine, optical fiber and industrial Ethernet 152. The processor is connected to the underground intrinsically safe switch 151 through optical fiber, the underground intrinsically safe switch 151 is connected to the aboveground switch 153 through the underground industrial Ethernet, and the aboveground switch 153 is connected to the ground monitoring room 160 through the aboveground industrial Ethernet to achieve data synchronization.

[0030] In order to realize the separate monitoring of the gas inside and outside the goaf, the present invention is provided with an electric rotating baffle 135; specifically, the electric rotating baffle 135 is hinged at the connection of the first gas pipeline 123 and the second gas pipeline 133, the inner diameter of the first gas pipeline 123 and the second gas pipeline 133 are the same, and the electric rotating baffle 135 is matched with the inner wall of the first gas pipeline 123 and the inner wall of the second gas pipeline 133. Among them, the electric rotating baffle 135 is processed and manufactured with high-strength, corrosion-resistant metal materials (such as stainless steel) to ensure that it has good durability and stability during use, and the shape and size of the electric rotating baffle 135 are customized according to the inner diameters of the first gas pipeline 123 and the second gas pipeline 133 to ensure that the baffle can fit closely to the inner wall of the pipeline to prevent gas leakage. The present invention sets the inner diameters of the first gas pipeline 123 and the second gas pipeline 133 to be the same in order to ensure that the electric rotating baffle 135 can maintain consistent sealing during the rotation process; the edge of the electric rotating baffle 135 is precisely processed to fit with the inner wall of the first gas pipeline 123 and the second gas pipeline 133 to form a tight sealing structure. In addition, a layer of special sealing material (such as sealant or sealing gasket) can be applied between the baffle and the inner wall of the pipeline to enhance the sealing effect and prevent gas leakage. In addition, the electric rotating baffle 135 is driven by a motor, which is connected to a communication module and receives remote control instructions from the ground monitoring room 160; when it is necessary to switch the gas collection source, the ground monitoring room 160 sends an instruction to the communication module, and the motor starts after receiving the instruction, driving the baffle to rotate to a specified position; in addition, the rotation angle and position of the electric rotating baffle 135 can be monitored and fed back in real time by installing corresponding sensors to ensure the accuracy and reliability of the control.

[0033] Furthermore, the video display screen 142 and the gas parameter display screen 122 are both arranged on the front panel of the protective shell 110, and hanging rings 111 are arranged on the left and right side panels of the protective shell 110. The protective shell 110 is horizontally hung on the mine sealing wall, the working face corner and / or the top wall of the mine at the head of excavation through the hanging rings 111.

[0034] Specifically, the multi-gas monitoring alarm 121 adopts a mining suspended multi-gas monitoring alarm model JD5X (A), which is used to detect the concentration of multi-gas components in the air of coal mines. The alarm is a voice broadcast type electronic instrument that adopts thermal catalytic principle, electrochemical principle, infrared principle, embedded microcontroller intelligent control, and three-digit digital tube display. It is mainly used for the detection and alarm of methane, oxygen, carbon monoxide, carbon dioxide, and temperature. It is an intelligent detection instrument with built-in temperature compensation and other functions, and has the characteristics of high accuracy, stability, reliability, and convenience.

[0035] The vacuum pump 131 uses the N811KTE vacuum pump, which is used for continuous extraction of gas during gas analysis. It is panel mounted, with a mounting hole spacing of 48mm. The interior is designed to be corrosion-resistant, and is particularly suitable for flue gas and comprehensive mine gas analysis. It can extract gas such as methane, SO2, NOX, CO2, CO, N2, and 02.

The mining ball-type explosion-proof camera uses network cable or optical fiber for power supply and data transmission, which is convenient for later maintenance. The internal structure of the ball machine is highly integrated, the circuit design is simple, and the heat dissipation is small, which is conducive to the normal operation of the camera under high temperature conditions. The most prominent feature of the mining ball-type explosion-proof camera is that the lens can be freely rotated horizontally and vertically, which is suitable for monitoring targets in large areas. The real-time video images and audio data captured by the camera are transmitted to the ground for display and playback, which can facilitate the ground monitoring room 160 to monitor the underground and conduct two-way voice communication.
