为了避免煤与瓦斯突出事故,根据国家安监总局28号文要求,基于煤矿瓦斯监控系统、人员定位系统、电力监控系统及计算机网络,建立了煤与瓦斯突出事故报警系统。以南山煤矿为例,介绍了防突工作面的传感器布置方法,突出事故报警系统的技术原理以及建设过程。实现了突出事故发生时系统能自动发出报警信号及报警短信,通知井下作业人员及时撤离的要求,对计算事故波及范围内的相关电气设备、电源及时断电,避免次生灾害地发生。
In order to avoid coal and gas outburst accident, according to the requirement of State Administration of Work Safety No. 28, based on coal mine gas monitoring system, personnel positioning system, power monitoring system and computer network, the coal and gas outburst alarm system was established. Taking Nanshan Coal Mine as an example, the sensor placement methods for outburst working face are introduced, the technical principle of the accident alarming system is highlighted, and the construction process is highlighted. The system can automatically send out alarm signals and alarm messages to notify underground operators of the timely evacuation requirements when outbreak of an accident, and timely discharge power to related electrical equipment and power sources in the range of accident accidents so as to avoid occurrence of secondary disasters.
