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。
According to the actual conditions of loose coal along the empty trough of 4308 fully mechanized Caving Face in Dongtan Coal Mine, the natural fire danger of gob-side entry is predicted through numerical simulation of spontaneous combustion process of loose coal in roadway. Prove its prediction accuracy can basically meet the needs of the scene.
