Abstract:
According to the characteristics of small coal mine fire zones around Daliuta Coal Mine Huojitu Shaft, the impact of small coal mine fire zones on Daliuta Coal Mine Huojitu Shaft was evaluated. Two treatment schemes for small coal mine fire zones were put forward, which were respectively stripping and backfilling fire extinguishing, and surface borehole grouting fire extinguishing. There were feasibility analysis, comparison and optimal selection for the two treatment schemes. The consequences showed that the treatment scheme of stripping and backfilling fire extinguishing could eradicate the fire zones thoroughly, and its last cost was relatively less. So it was more suitable for the treatment of small coal mine fire zones around Daliuta Coal Mine.
