Embodiment 1
[0045] Such as figure 1 As shown, in order to improve the utilization rate of abandoned mines, the present application provides a method for producing hydrogen by utilizing abandoned mines, the method comprising:
[0046] Step S101, blocking the main shaft 1, the auxiliary shaft 2 and the periphery of the coal pillar 3 at the boundary of the minefield in the abandoned mine;
[0047] refer to Figure 4 It can be seen that it specifically includes the following steps:
[0048] Close the main shaft 1 and auxiliary shaft 2 in the abandoned mine;
[0049] Preferably, waste coal gangue and soil can be used to backfill the main well 1 and the auxiliary well 2. Of course, geotechnical filling or grouting can also be used to seal. This embodiment does not specifically limit the sealing method, as long as it can Realize that the sealing methods of main well 1 and auxiliary well 2 belong to the protection scope of the scheme;
[0050] Close the main shaft 1 and the auxiliary shaft 2 ...
Embodiment 2
[0069] Such as figure 2 As shown, the application provides a method of utilizing abandoned mines to produce hydrogen, the method comprising:
[0070] Step S201, blocking the main shaft 1, the auxiliary shaft 2 and the periphery of the coal pillar 3 at the boundary of the minefield in the abandoned mine;
[0071] Step S202, opening at least one first borehole 5 on the ground leading to the remaining coal resources 4;
[0072] Step S203, opening at least one second borehole 7 on the ground through the fissure zone above the goaf 6;
[0073] Specifically, due to the low density of the gas composed of hydrogen and carbon monoxide, it is only necessary to extract the gas composed of hydrogen and carbon monoxide in the fissure zone above the goaf; preferably, the second borehole 7 is set to multiple, and One-to-one correspondence with multiple goafs 6, during use, the gas generated by the reaction is continuously extracted to the ground through multiple second boreholes 7, so as ...
