摘要
Abstract
The spacing between the 301 fully mechanized coal mining face laying 12 coal mine and 12 day-coal is 10 ~ 20m, and the two layer of coal has the unminable coal with the thick of 0.3~3m. With the working face advancing and roof caving, the float coal thickness increases in goaf, which provides material conditions for spontaneous combustion of coal. And the goaf of contiguous seams is a loose, the air leakage of goaf is serious, the lfoat coal spontaneous combustion risk increases. Therefore, it is important to study the related technical measures contiguous seams ifre prevention.关键词
