| 摘 要： | 基于气压计基点测定法,介绍了保德煤矿通风阻力测定的布置方案和计算理论依据。通过对现场测定数据的计算和分析,结果表明：进风段、用风段、回风段3段通风阻力占总阻力的比例分别为30.21%、24.97%、44.82%;矿井等积孔为10.33 m2,总风阻为0.013 N.s2/m8,通风系统自然风压为45 Pa,矿井通风难易程度为容易。针对回风段阻力比较高的情况,根据现场实际情况分析了原因,提出了合理的建议。经计算主测定路线上的通风阻力测定相对误差为1.94%,其精度符合要求。该测定结果可以作为矿井通风系统改造、优化和管理的依据。

| Abstract: | Based on the base point measuring method of the barometer,the layout alternatives and the calculation theoretical basis of the ventilation resistance measurement in Baode Mine were introduced.With the calculation and analysis on the site measured data,the results showed that the ventilation resistance in the air income section,the air applied section and the air retuning section was individually taken 30.21%,24.97% and 44.82% of the total resistance.The equivalence hole of the mine ventilation shaft was 10.... |
