摘要
根据通风阻力上限值和通风容易矿井的通风参数,研究了不同通风难易程度下矿井风量和等积孔的关系,确定了通风困难线和容易线方程,绘制了通风难易程度两线三区图,并提出评价通风难易程度的通风难易系数KT,根据KT值确定通风难易程度。现场应用实践表明符合矿井实际情况,能够有效地评价矿井通风难易程度。
According to the upper limit of ventilation resistance and ventilation parameters of modern mine, the relationship between mine air volume and equal pore volume under different ventilation difficulty degree is studied, the equations of ventilation difficulty line and tolerance line are determined, the two lines and three areas of ventilation difficulty degree are drawn, and the evaluation of ventilation difficulty degree is put forward, according to KTvalue, the ventilation difficulty degree is determined. The field application shows that it is in line with the actual situation of the mine and can effectively evaluate the difficulty of mine ventilation.
