摘要

针对煤田火区的探测、控制和监测,我们将互联网创新成果与传统地质勘探技术深度融合,开发了具有火区范围和中心温度探测、连续采集、高温探测、远程控制等功能的永久性无线传感器网络远程监测系统。设计了一种新型传感器节点,该节点可与极-偶极装置连接,并部署在地下火区巷道中进行监测。带有保护电路的太阳能供电装置为现场数据采集网络持续提供足够的能量。数据通过移动连接网络和Internet传输到监控中心进行远程控制和监控。开发的监测系统已在新疆12个火区同时部署,已运行45个月,这意味着技术措施可以保证监测系统的长期稳定维护和自由运行。乌鲁木齐监测中心已接收110余万份现场数据,经授权可永久保存,可自由查询。这些信息为新疆大面积煤炭自燃火区的管理提供了基础数据。结果表明,充分利用互联网进行物探监测优化集成,对促进煤炭地质勘查创新和提高产能具有重要意义。

HIGH RESOLUTION RESISTIVITY DETECTING AND REMOTE INTERNET MONITORING OF COALFIELD FIRE
For detecting, controlling and monitoring the coalfield fire area, we deeply integrated Internet innovative achievement into traditional geological exploration technology, and developed a permanent wireless sensor network remote monitoring system with the functions of detecting the range and central temperature of fire area, continuous collection, high temperature detection, remote control, etc. The new sensor node, which can be connected with pole-dipole device, was designed and deployed in the underground fire zone roadway for monitoring. The solar power supply device with protective circuit supplied continuous enough energy to on-site data collection network. The data was transmitted to monitoring center through the mobile connection network and Internet for remote control and monitoring. The developed monitoring system that was deployed simultaneously in 12 fire areas of Xinjiang has been working for 45 months, which means technical measures can guarantee long-term stability maintenance free operation of the monitoring system. Urumqi monitoring center has received more than 1.1 million field data that can be preserved permanently and queried freely after authorization. This information provided basic data for the management of large area of coal spontaneous combustion fire area in Xinjiang. The results show that fully utilizing the Internet for optimization and integration in geophysical exploration and monitoring has the vital significance to promote coal geological exploration innovation and production capacity.
