摘要
为了治理老石旦煤矿031601工作面采空区的自燃,在认真详细分析了发火的原因情况下,并且根据采空区的实际情况,采取了井下均压通风防灭火技术。实践应用表明:在火区的上隅角CO浓度从10×10-6降到0,有效地起到了防灭火的作用,保证了工作面的安全生产。
In order to control the spontaneous combustion of 031601 working face in Laoshidan coal mine, the reasons of the fire are analyzed in detail, and according to the actual situation of the mined out area, the technology of underground pressure balanced fire control and fire extinguishing is adopted. Application practice shows that in the zone at the upper comer of the CO concentration from 10×10-6 down to 0, effective fire prevention and extinguishing played a role, to ensure the safety production of working face.
