泉店煤矿通风系统优化改造

Optimal Modification of Quandian Coal Mine Ventilation System

中央并列式通风系统,井底车场区域通风网络复杂,由于通风系统中角联巷道的存在,造成自然配风量极为不均衡,导致主井底区域机电硐室和附近巷道风流不稳定。矿井两翼独立通风可靠程度大为降低,存在部分机电硐室温度高、系统不合理等重大隐患,通过对矿井通风网络系统优化改造,达到了降温、降阻、风量分配更趋合理等目的,消除了矿井不安全隐患,确保矿井通风安全。

Central parallel ventilation system and ventilation network of mine shaft bottom area is complex.Extremely uneven of natural distribution air volume is caused because of the occurrence of angle connection roadway in ventilation system,which result in unsteady wind in electrical chamber and nearby roadway of main shaft bottom area.Independent ventilation reliability of mine wings is greatly reduced.There are significant risks of high temperature in part of the electrical chamber and unreasonable system,etc.through the optimal modification of coal mine ventilation network,the propose of reducing temperature,diminishing resistance,distributing air volume reasonably is achieved,which eliminate the hidden dangers of mine and guarantee ventilation safety of coal mine.
