Research on fire prevention and extinguishing technology in underhand working face of easy spontaneous combustion coal seam
IOP Conference Series: Materials Science and Engineering
The management of fire prevention and extinguishing in goaf becomes a major problem due to short spontaneous combustion period, poor roof caving conditions, large air leakage in goaf and difficulties for grouting. Oxygen consumption rate and the productivity of carbon monoxide are measured through the XK-Ⅵ spontaneous combustion test-bed, while prediction index gas for spontaneous combustion of the coal is obtained. Through the engineering practice test, the range of the gob "triple-zone" underdoi:10.1088/1757-899x/729/1/012013 fatcat:7y2girhpvnd2jggjo6qdrgo5ea
