摘要
根据综放工作面开采后采空区遗煤自燃特点,采用实验测定的关键参数,结合现场可测参数,推算现场不同条件下引起煤体自燃的极限参数,判定实际条件下建新煤矿4103综放面"三带"分布规律,自燃危险区域和安全推进速度,为综放面采取针对性的自燃预防措施提供理论依据。
It＇ s very important to determine the spontaneous combustion risk area of goal＇ s wasted coal in normal mining period of fully mechanized caving face. According to the characteristics of spontaneous combustion of goal＇ s wasted coal, using test measurement and field measurement method, the limit parameters which causes the coal spontaneous combustion in different situations are calculated and ＂three zones＂ distribution laws, spontaneous combustion risk area and safety mining speed of N04103 fully mechanized caving face of Jianxin Mine are determined. The research can provide theoretical basis for preventing seam spontaneous combustion.
