Embodiment Construction
[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0043] Embodiments of the present invention are as follows:
[0044] The gas concentration data of a coal mine mining face is collected by the gas concentration sensor as the research object of the embodiment. At the same time, the operation type tracking and recording in the cycle period is manually carried out as a sample library. The specific implementation process is as follows figure 1 As shown, the specific method is as follows.
[0045] Step 1. Automatically and continuously obtain the dynamic time series data of gas gushing from the tunneling face through the mine safety monitoring system. In this embodiment, the mine uses the gas data obtained by the KJ90 (substa...
