[0002] In the mining industry, gas environment monitoring in mines is a key link to ensure safe production. However, traditional methods of observing, detecting, monitoring, sampling and analyzing gas in mines have many shortcomings. At present, gas inspectors of mine workers need to carry a variety of observation, detection, monitoring and sampling instruments on foot to the target closed wall location for on-site operation. This method is not only labor-intensive and inefficient, but also affected by the complex environment of the mine, and personnel face many challenges in walking safely.

[0003] Specifically, the traditional method requires personnel to carry multiple instruments, and the routes are often remote and in harsh environments, which undoubtedly increases the risk of injury. At the same time, due to manual operations, the accuracy of data observation, detection, monitoring and sampling is difficult to guarantee, and there are large manual errors. In addition, the traditional method cannot realize the visualization of field data, and there are delays in data extraction and transmission, resulting in the inability to synchronize data in real time above and below the well, and the inability to carry out timely and effective management and control.

[0014] In a third aspect, the present invention provides a computer storage medium, wherein the computer-readable storage medium stores instructions, which, when executed on a computer, enable the computer to execute the methods described in the above aspects.

[0025] The communication module includes an underground intrinsically safe switch installed in the mine, an above-ground switch installed above the mine, optical fiber and industrial Ethernet. The processor is connected to the underground intrinsically safe switch through optical fiber, the underground intrinsically safe switch is connected to the above-ground switch through the underground industrial Ethernet, and the above-ground switch is connected to the ground monitoring room through the above-ground industrial Ethernet to achieve data synchronization.

[0026] Specifically, the display screen is arranged on the front panel of the protective shell, and hanging rings are arranged on the left and right side panels of the protective shell. The protective shell 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.

[0027] In addition, before installing the device, relevant cables need to be laid underground.

[0028] Among them, the methane sensor uses a high-concentration laser methane sensor for mining with model GJG100J.

[0032] The temperature sensor uses a KGW5 digital temperature sensor for mine intrinsic safety. This temperature sensor is used to measure the ambient temperature of coal mines in order to monitor the occurrence of fires. This temperature sensor acts on the outside of the closed wall, the corner of the working face, the head of the excavation, the principle of spontaneous combustion of coal seams, the thermal storage of coal oxidation, the geological temperature analysis of the gas generated, and the climate conditions analysis of the mine safety production head of the excavation.

[0033] The camera uses a KBA12 mining intrinsically safe audio-video camera, which is used to capture real-time video images and audio data of underground closed walls, working face corners, and excavation heads, and transmit them to the ground monitoring room for display and playback, which can facilitate the ground monitoring room to monitor the underground and conduct two-way voice communication, and synchronize data in real time above and below the well. The camera can operate normally in places with explosion hazards such as gas, methane, coal dust, and dust.
