摘要
本文中介绍了石台煤矿通风现状调查结果,提供了中央风井主扇实测性能曲线和通风阻力分布及地面漏风情况。在查明影响四采区增风主要因素的基础上,结合该矿实际,拟定了十二个较为可行的增风方案,分折了电子计算机的模拟结果。
A presentation is given of the present ventilating conditions in Shitai Coal Mine, togther with the performance curve of the main fan at the central ventilation shaft and the distribution of ventilating resistances and leakages of air currents from the surface. With the chief factors responsible for ventilation decrease in working section IV pinpointed and the actual conditions of this mine considered, twelve acceptable approaches to increased air currents are offered and computer-analyzed, hence measures for ventilation improvement
