摘　　要：为了对井下瓦斯进行及时、有效地监控,提出将节点风量覆盖法作为瓦斯传感器放置的理论依据.首先建立通风网络各节点的瓦斯比例矩阵以及风量覆盖矩阵,定义目标函数及约束条件,将问题转换为0-1规划问题,给定覆盖度具体数值,利用隐含枚举法求得最佳布点.以一小型矿井通风网络为研究对象,结果表明,在瓦斯安全监控过程中,通过合理确定瓦斯传感器的数量和覆盖度数值,应用恰当的0-1规划法求解通风网络,可以求得瓦斯传感器的宏观布点.To monitor methane effectively and timely, coverage of node flowrate method was put forward as theory base. Methane proportion matrix and airflow matrix of all nodes in ventilation network were solved at first, objective function and constraint were defined, then the problem of placement was transferred to 0 - 1 programming. After giving value of coverage, the best placement of methane sensors was got using hide list method. Using ventilation network of a small mine as the research object, the result shows that placement of methane sensors can be figured by proper methane sensor number, coverage value and 0 - 1 programming method chosen according to different ven- tilation networks.
