东滩矿4308综放面沿空巷道自然发火预测

摘要

mechanized Top－ coal Caving Face in Dongtan Mine－ Based on thereal conditions at the tailgate close to gob 4039 in the No. 4308 fully－ mechanized top－ coal caving face, the process of spontaneous combustion of loose coal is simulated numerically and the spontaneous combustion of loose coal is predicted.%根据东滩矿4308综放面沿空顺槽松散煤体实际条件，通过巷道松散煤体自然发火过程数值模拟，预测沿空巷道自然发火危险性。证明其预测精度能基本满足现场需要。
