煤矿矿井通风降阻方案论证研究

Demonstration study of ventilation resistance reduction scheme in coal mine

矿井通风阻力测定是获取煤矿井巷风阻和矿井通风阻力分布重要措施。对煤矿实际的通风系统和通风阻力测定数据,基于煤炭科学研究总院自主开发的矿井通风智能分析系统,建立煤矿三维通风仿真系统,并解决现存通风系统局部问题。仿真结果表明,通风系统部分区段通风阻力较大,结合矿井实际提出降阻方案并进行分析论证。

The measurement of mine ventilation resistance is an important measure to obtain the wind resistance and mine ventilation resistance distribution.Based on the actual ventilation system and ventilation resistance measurement data of the coal mine,the mine ventilation intelligent analysis system independently developed by the General Institute of Coal Science,the three-dimensional ventilation simulation system of Xiaojiawa Coal Mine is established.The ventilation resistance of the ventilation system is large,and the resistance reduction scheme is put forward in combination with the actual situation of the mine and analyzed and demonstrated.
