When performing igniting operation, certain flow air is first placed on coal seam 5 by the feeding of continuous pipe 1 in boundling pipe device and is pre-positioned
In the burner put, then a certain amount of silane is sent into burner by continuous pipe 1, at the same time by propane also by even
Continuous pipe 1 is sent into, and silane runs into air spontaneous combustion so as to which the propane that ignites, propane burning again light coal seam 5.After coal seam 5 is lighted, in coal
Layer 5 in formed combustion chamber 13, oxygen can will be sent into continuous pipe 1, water is sent into continuous pipe 1, carry out gasification production (or gasification adopt
Coal operation), the coal gas that gasification produces is discharged to ground 4 for later use by going out gas drilling hole 3.
C) in fluid injection, by set the sensor of nozzle end survey coal seam 5 burn, vaporized state, and pass through
Control device is monitored, while will export gas composition data access control device, by the number such as sensor, gas composition
According to analysis, and by autocontrol valve etc., the flow of each fluid of adjust automatically, so as to control oxygen concentration, water oxygen ratio, vapour
The technological parameters such as oxygen ratio, outlet gas composition to be adjusted, realize the stability contorting of production process.
D) after the coal mining activity process that gasifies, by bundle pipes injector 12, bundle pipes preventer, reel 9 association
With control, by the way that bundle pipes are above carried, nozzle is moved to 5 next pre-position of coal seam.
Some one exemplary embodiments that only the invention has been described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as to the present invention
