摘要
Abstract
To prevent the threat of spontaneous combustion in mining coal seam, and focus on prevention and control of sponta-neous combustion in adjacent overlying coal seam goaf. In this paper, SF6 tracer gas is used to measure air leakage qualitatively. Through the observation of air leakage at different intervals of fully mechanized mining face in Shendong Mining Area, the law of air leakage at different intervals of coal seams is studied and summarized, which provides a basis for taking appropriate air leakage control measures in mining close distance spontaneous combustion coal seams, and reduces the possibility of spontaneous combus-tion in goaf as far as possible. The control of air leakage in goaf provides scientific basis and effective preventive measures.关键词
