摘要

A method for preventing the creation of an ignitable gas mixture in the case of an entering gas-guiding cavities of discarded degradation regions of the stone carbon, which extends deep construction and berg, characterized in that, by means of a connected to the end of a casing, the gas concentration measuring device is monitored and in the borehole interior before the occurrence of a critical concentration of a water vapor in the upper bore hole region is introduced in such a way that the water vapor in the drilled hole a the depth of from the drilled hole which is directed opposite to the following flow of gas flow is formed.
