The invention provides a mining area surface gas overflow dynamic monitoring and intelligent safety evaluation method. The method comprises the following steps: planning monitoring subareas, and formulating a monitoring route; a gas collecting and analyzing instrument is installed on a vehicle, a methane collecting terminal of the instrument is located outside the vehicle, and the gas collecting and analyzing instrument is connected into a Beidou satellite positioning system; starting the gas collecting and analyzing instrument, controlling the vehicle to advance along the monitoring route according to a preset speed, and observing a monitoring result fed back by the gas collecting and analyzing instrument in the vehicle sailing process; and comparing the acquired data with a threshold value, comparing the acquired data with a preset threshold value, and performing early warning when the acquired data deviates from the threshold value. According to the invention, complementary advantages of ground surface monitoring and specific high-altitude monitoring are realized, gas concentration abnormal monitoring points in a region can be automatically identified, a region gas concentration monitoring data set can be formed, a gas change rule in a mining area can be dynamically mastered, and online early warning can be provided for life and property safety caused by potential gas inrush.

本发明提供了一种矿区地表瓦斯溢出动态监测及智能化安全评价评价方法。步骤包括：规划监测分区，制定监测路线；在车辆上安装瓦斯采集分析仪器，该仪器的甲烷采集终端位于车辆外部，瓦斯采集分析仪器接入北斗卫星定位系统；开启瓦斯采集分析仪器，控制车辆按照预设速度沿着监测路线行进，并在车辆走航过程中观测瓦斯采集分析仪器反馈的监测结果；将获取到的数据与阀值进行比对，并与预设阀值进行比对，偏离阀值时进行预警。本发明实现了地表监测与特定高空监测的优势互补，便于自动识别区域内的瓦斯浓度异常监测点，可形成区域瓦斯浓度监测数据集，而且能够动态掌握矿区内瓦斯变化规律，能够为潜在的瓦斯突涌而造成的生命财产安全提供在线预警。
