城郊煤矿通风阻力测定及系统优化分析

Resistance Measurement of Ventilation System and Snalysis of System Transformation in Chengjiao Coal Mine

针对城郊煤矿通风系统现状,选取3条主测路线及3条辅测路线对矿井通风阻力进行测定。为了保证测试的精确性,现场采用两点同时法进行测定,从而准确掌握矿井各巷道的阻力分布情况,有利于获得可靠的基础参数,从而为通风系统优化提供依据。利用通风网络解算软件对当前的通风系统进行解算,验证测定结果的可靠性,并针对城郊煤矿东翼回风下山贯通后的通风系统进行解算分析;根据阻力测定结果,查找通风系统存在的问题并提出建议。

According to the state of ventilation system in Chengjiao Coal Mine, selecting three main test routes and three auxiliary routes which covered all of the mine, in order to ensure the accuracy of the test, two points simultaneous determination was used in the field , so we mastered the distribution of resistance of the roadway in mine in order that we could obtain reliable basic parameters to provides the basis of optimization of mine ventilation system. By the result of resistance measurement, we put forward some reasonable proposals under the existing proble problems and verified through ventilation network. Finally, the modified ventilation system was analyzed.
