bekæmpelse af "rockburst" (eksplosivt brud af fjeld)
prevention of rock bursts.

efter min mening er det især etableringen af den første forbindelse i ikke-udnyttet fjeld, som frembyder de største vanskeligheder.
at the beringen colliery of the same company, where a high-pressure compressed air system is available, air was injected into one borehole in order to link it by a path through the seam to a second borehole.

afgasningen af et kulholdigt fjeld ved udvinding i et kullag beliggende nederst i kullejet har gentagne gange været genstand for ind gående undersøgelser, og betydningen af denne afgasning er velkendt.
many detailed studies have been made of the degassing of coal measures during extraction of a seam at the bottom of the coal measures and a great deal of information is available on the quantities of firedamp which can be captured.

i forsøgene vedrørende in situ-produktion af kulgas i stor dybde, som vil blive behandlet længere fremme, tillægger jeg afgasningen af det overliggende fjeld stor betydning.
in the experiments relating to in-situ gasification of deep-lying deposits, which will be discussed, great importance is attached to degassing of the superjacent strata.

(4) hydraulisk opsprækning af kulholdigt fjeld i luisenthal-minen af r. muller og g. kneuper, saarbergwerke a.g., saarbrücken.
fraccen (hydraulic breakage of the coal) at the luisenthal pit r. müller and g. kneuper, saarbergwerke a. g., saarbrücken.

- forbedring af varmeregnskabet ved formindskelse af varmetabet på grund af opvarmning af fjeldet samt vandfordampning;
- high gas flows in small-diameter boreholes; - greater pfficiency by increased speed of gas/solid reaction and transfer; - improvement of the thermal balance by a reduction in heat losses through heating of rocks and water evaporation; - a reduction in the amount of energy required to overcome the pressure drop in the underground circuits;
