摘要
211203工作面受到上覆6号煤层采空区遗煤自燃影响,且工作面开采的11号煤层具有自然发火倾向,通过对工作面采取的瓦斯治理措施及效果进行分析基础上,提出了针对采面生产实际的通风方式,并具体论证了负压通风及均压通风可行性。工作面采用上述通风方式后,安全推进约820m,未出现有害气体超标情况。
211203 working face is affected by the spontaneous combustion of the remaining coal in the gob of No.6 coal seam overlying,and coal seam 11 mined in the working face has the tendency of spontaneous combustion,based on the analysis of the gas control measures and effects adopted in the working face,the ventilation mode for the actual production of the mining face is put forward,the feasibility of negative pressure ventilation and even pressure ventilation is demonstrated in detail.After the working face adopts the above ventilation mode,safe advance about 820m,no harmful gas exceeding the standard.
