Control of gas emission in a working end area during its chipping away operation
Meshcheryakov, D. A. Llgol', 1997, (5) 46-47. (In Russian) In a chipping away zone during coal mining from bed i4 in the Severnaya mine, Russia, gas emissions are up to 2.5-4 fold higher than those predicted within 5 years from the chipping away operation. Bed degassing through wells can control these excessive emissions. 9BlOI 600
