Bei Beginn des Betriebes wird zunächst der Verdichter 9 in Gang gesetzt,, wodurch. der Hohlraum h mit Pressluft erfüllt wird, welche die benachbarten Kohlenschichten austrocknet
EMI2.1
Sollte das Gefüge der Kohle zwischen den Rohren. f und i zu dicht sein, so kann durch eine vorherige Sprengung dieses Gefüge gelockert werden.
Wenn durch die Entgasung ein Streifen, etwa von der Länge A, B, C, D, ausgebeutet ist, so kann durch Niederbringen eines zweiten Entnahmerohres in entsprechendem Abstand vom Rohre f ein weiterer Kohlenstreifen in Angriff genommen werden.
Die in Fig. 2 dargestellte Einrichtung unterscheidet sich von der in Fig. 1 dargestellten nur dadurch, dass das Rohr f innerhalb des Rohres i niedergebracht ist. Hierdurch werden die Kosten für das besondere Einbohren oder Einspülen des Rohres f vermieden oder doch ganz wesentlich verringert.
Die Regelung der Gasbildung erfolgt durch Drosselung der Querschnitte der Rohre f und i sowie durch Änderung der Höhenlage dieser Rohre.
PATENT-ANSPRÜCHE :
1. Verfahren zur Ausbeutung nicht abbauwürdiger Brennstonlager, besonders Braun- kohlenlager, mittels Bohrlöcher unter Verbrennung und Entgasung der Lager auf ihrer natürlichen Lagerstätte, dadurch gekennzeichnet, dass die Verbrennung und Entgasung durchströmende Druckluft bewirkt wird, die an einer Stelle in das brennende Lager eingeblasen und an anderer Stelle als nutzbares Gas über Tage abgeleitet wird.

At the start of operation, the compressor 9 is first started, whereby. the cavity h is filled with compressed air, which dries out the neighboring coal layers
EMI2.1
Should be the texture of the coal between the pipes. If f and i are too dense, this structure can be loosened by a previous explosion.
If a strip of length A, B, C, D, for example, has been exploited by the degassing, another strip of coal can be tackled by lowering a second extraction tube at a corresponding distance from tube f.
The device shown in FIG. 2 differs from that shown in FIG. 1 only in that the pipe f is brought down inside the pipe i. As a result, the costs for the special drilling or flushing in of the pipe f are avoided or at least significantly reduced.
The gas formation is regulated by throttling the cross-sections of the pipes f and i and by changing the height of these pipes.
PATENT CLAIMS:
1. A method for the exploitation of burnt clay deposits that cannot be mined, especially brown coal deposits, by means of boreholes with combustion and degassing of the deposits on their natural deposits, characterized in that the combustion and degassing is effected by compressed air flowing through, which is blown into the burning warehouse at one point and is discharged elsewhere as usable gas above ground.
