Prevention and control for coal spontaneous combustionin by fully mechanized top-coal caving of extremely thick coal seam

摘要：

Seam spontaneous combustion control is one of the key technical problems in fully mechanized top coal caving technology.The seam spontaneous combustion would be often occurred specially in special thick seam with a short period of spontaneous combustion and rich gas.Taking some coal field as a research object,the paper presented the features and laws of spontaneous combustion in caving gob,analyzed a general relationship between the gas drainage and spontaneous combustion,and summarized conventional control technologies for coal spontaneous combustion occurred in fully mechanized coal mining.
