摘要
针对贝勒矿的井下采场与掘进工作面爆破环境实际情况,依据巷道通风流动性特征,对不同通风量计算方案进行数值模拟分析。在矿山巷道掘进过程中,对掘进工作面的需风量计算公式进行详细的论述,以计算公式为基础,确定掘进工作面排除炮烟所需风量。
According to the actual situation of blasting environment of underground stope and heading face in Baile Mine,according to the characteristics of ventilation fluidity of roadway,the numerical simulation analysis of different ventilation calculation schemes was carried out.In the process of mine roadway excavation,the formula for calculating the air demand at the heading face is discussed in detail.Based on the formula,the air demand for eliminating smoke at the heading face is determined.
