中文摘要：

为保障煤矿安全生产,预防煤与瓦斯突出,经常需要在井下某些位置增设瓦斯监测点。首先建立节点有效监测矩阵,利用监测等级确定瓦斯传感器的有效报警时间,构建瓦斯传感器布设模型;然后根据信息素策略和概率转移策略,设计求解瓦斯传感器布设模型的算法流程,并通过混合蚁群算法（HACA）进行求解。最后将HACA应用到阳泉煤业集团有限责任公司五矿贵石沟矿井瓦斯传感器布设实践中。结果表明,需要增设瓦斯传感器的数量与监测有效等级之间存在线性关系。

英文摘要：

As a general rule,in order to ensure safe production coal,it is often a must to install additional gas sensors at some locations in a mine. A model was built for arranging gas sensors. A HACA process was designed for solving the model. The process was applied to the mine 5 Guishigou coal mine of Yangquan coal group limited liability company. The results show that there is a linear relationship between the effective monitoring level and the number of gas sensors that need to be added.
