摘要
为准确掌握红阳三矿通风阻力分布规律,为通风系统优化改造提供数据支持,应用气压计法和压差计法相结合的方式对其通风阻力进行了测定。通过对测定数据进行处理与分析,得到通风阻力、三区阻力分布、等积孔等指标。根据该类指标,分析了矿井通风系统存在的问题,并对通风系统进行了优化改造。研究表明:矿井等积孔为6.55 m2,为通风容易矿井;针对回风段阻力偏大的问题,通过采取扩大巷道断面、构筑物调节和消除局部阻力的综合措施可使南北风井阻力降低270~380 Pa。
In order to accurately master the ventilation resistance distribution regularity of Hongyang No. 3 Coal Mine and provide the reliable data support for the optimization and transformation of the ventilation system of the mine,the ventilation resistance is measured by combing with the barometer method and differential pressure gauge method. By processing and analyzing the ventilation resistance measurement data,the indicators such as ventilation resistance,resistance distribution of three-zone and equivalent orifice. Based on these indicators,the problems of the ventilation system is analyzed,and it is optimized. The study results show that the equivalent orifice is 6. 55 m2,which indicated that the coal mine is easy to ventilate; the resistance of return airway is larger than others,and it can be reduced by 270 ~ 380 Pa in both and north air shaft by taken the measures of expanding the roadway section,adjusting the structures and removing the local resistance.
