通过对发耳煤矿一、三采区通风网络图的定性分析和对通风阻力测定结果的定量分析,全面掌握了一、三采区合并前通风网络结构和阻力分布情况,结果表明:一采区通风系统总体合理可靠,阻力分配合理;三采区通风路线较复杂,通风阻力主要分布在回风段。根据通风阻力测定结果建立了一、三采区通风系统参数库。对通风系统现状的分析和通风系统参数库的建立,有助于一、三采区合并过程中通风网络结构的选择和通风系统改造方案的选取。
Through the qualitative analysis of the ventilation network diagram of the first and third mining areas in Fuer coal mine and the quantitative analysis of the ventilation resistance measurement results, the distribution of the ventilation network structure before the merger in the first and third mining areas and the resistance distribution are fully mastered. The results show that: Ventilation system is generally reasonable and reliable, reasonable distribution of resistance; Ventilation route is more complex in the three mining areas, the ventilation resistance is mainly distributed in the return air section. According to the ventilation resistance measurement results, the first and the third mining area ventilation system parameter database were established. The analysis of the current status of the ventilation system and the establishment of the ventilation system parameter database are helpful for the selection of the ventilation network structure and the selection of the ventilation system reforming plan during the merger of the first and third mining areas.
