or, the first preset time period is any time period of 5-30 minutes; the preset concentration range is 0.05% to 5%; the preset times range is 5-40 times; the determining module is specifically configured to: if the gas concentration is in the range of 0.05% to 5% and the number of times is in the range of 5-40 times, it is determined that there is a risk of coal and gas outburst.
7. The apparatus of claim 6, wherein the sending module is specifically configured to:
and sending dangerous prompt information of abnormal gas to the client.
8. The apparatus of claim 6, wherein the sending module is specifically configured to:
and sending dangerous prompt information of coal and gas outburst to the client.
9. The apparatus of claim 6, wherein the apparatus further comprises:
the second acquisition module is used for acquiring the gas concentration at each moment in a second preset time period;
the sending module is further configured to send a corresponding relationship between each moment and the gas concentration to the client, so that the client displays the corresponding relationship.
10. The apparatus of claim 6, wherein the first predetermined time period is a time period from a specified time point that has elapsed to a current time point.
11. An electronic device, the electronic device comprising: the device comprises a shell, a processor, a memory, a circuit board and a power circuit, wherein the circuit board is arranged in a space surrounded by the shell, and the processor and the memory are arranged on the circuit board; a power supply circuit for supplying power to each circuit or device of the electronic apparatus; the memory is used for storing executable program codes; the processor executes a program corresponding to the executable program code by reading the executable program code stored in the memory, for executing the gas hazard warning method in a coal mine according to any one of the preceding claims 1 to 5.
