摘　　要：以峰峰集团大淑村煤矿为例,对该矿高、低负压抽采系统进行优化改造的升级工作。通过采取增设新管道井、更换大管径抽采管路及并网提压等措施,有效减小矿井抽采管网阻力,提高井下瓦斯抽采管路负压,优化管网布置,大幅度提升了矿井的抽采能力。Former methane high and low pressure drainage system in Dashu Cun Colliery is transformed and optimized.By installing new pipe wells,replacing large diameter drainage pipelineand pipeline pressurization,etc.,the drainage resistance of the mine has been reduced effectively,negative pressure of drainage pipeline has been increased and drainage pipeline has been reasonably arranged,the capacity of the extraction system has been greatly improved.

关 键 词：瓦斯抽采 管道井 抽采阻力 负压
