SOLID-FUEL GAS GENERATOR FOR COAL BED DEGASSING

摘要

FIELD: mining. ^ SUBSTANCE: proposed gas generator comprises armored and nonarmored tubular charges of solid fuel accommodated on geophysical cable with fireproof coat, detonation igniter including blast cartridge and detonating cord. Said detonation igniter is accommodated in armored charge, second is seen from below, and upper armored charges. Channel of lower armored charge accommodates igniter representing an electric igniter connected in series with blast cartridge at preset distance therefrom. Gas generator bottom face is tightly plugged. ^ EFFECT: producing multiple elongated fractures in coal bed at low hydrostatic pressure, ruling out of gas generator upward travel. ^ 3 dwg
