运河煤矿通风阻力测定及均衡通风优化研究

摘要

从运河煤矿通风系统的实际情况出发，在矿井通风阻力测定的基础上，对矿井通风系统存在的问题进行分析，并对其实际状况进行了总体评价。在对该煤矿可能采用的通风优化方案分析论证的基础上，运用“均衡通风”原理优化矿井通风系统的方法，通过模拟解算，优化后的通风方案能够满足全矿井5a内各个时期的均衡通风和防灭火的需要。%Starting from the actual situation of the ventilation system in Yunhe Coal Mine and based on the measurement of the ventilation resistance, analysis was made in this paper on the existing problems of the ventilation system in this mine and overall evaluation was carried out on its actual situation. Based on the analysis and demonstration of the optimization ventilation scheme which may be adopted in Yunhe Mine, the mine ventilation system was optimized by using the “balanced ventilation”principle, and through the simulation calculation, the optimized ventilation scheme can meet the requirements for balanced ventilation and fire control of the whole mine in each period within 5 years.
