葫芦素煤矿通风阻力测定研究

Measurement of Ventilation Resistance in Hulusu Coal Mine

全面、精确掌握中天合创能源有限责任公司葫芦素煤矿(以下简称“葫芦素煤矿”)通风系统现状,确定矿井通风系统阻力具体分布情况,发现通风阻力较大的区段和地点,以便优化通风系统,使之更经济合理。葫芦素煤矿联合黑龙江科技大学采用气压计逐点测定法对煤矿通风系统进行了阻力测定,最终得出:煤矿各采掘工作面均能够实行独立通风,通风设施完善,通风管理工作较好;中央风井通风阻力为1580 Pa,西风井通风阻力为1759 Pa;中央风井的等积孔为7.9 m^(2),西风井的等积孔为4.9 m^(2),均属于通风容易矿井。建议进一步优化中央风井和西风井的风量分配,降低通风阻力,节约通风成本。

Fully and accurately grasp the current situation of the ventilation system in Hulusu Coal Mine of Zhongtian Hechuang Energy Co.,Ltd.(hereinafter referred to as Hulusu Coal Mine),determine the specific distribution of the resistance of the mine ventilation system,and find the sections and locations with large ventilation resistance in order to optimize the ventilation system and make it more economical and reasonable,Hulusu Coal Mine and Heilongjiang University of Science&Technology adopted the barometer point-by-point measurement method to measure the resistance of the coal mine ventilation system.Finally,it was concluded that each mining face of the coal mine could implement independent ventilation,the ventilation facilities were perfect,and the ventilation management was good;the central air shaft ventilation resistance was 1580 Pa,the west air shaft ventilation resistance was 1759 Pa;the equal pore volume of the central air shaft in Hulusu Coal Mine was 7.9 m^(2),and that of the west air shaft was 4.9 m^(2),both belonging to the mine with easy ventilation.It was suggested to further optimize the air volume distribution of central air shaft and west air shaft,reduce ventilation resistance and save ventilation cost.
