《煤矿安全规程》监控、通信与监视修订意见

提出了《煤矿安全规程》修订应增加矿井移动通信、广播通信、视频监视、人员定位、煤炭产量监测、矿井火灾监控、矿山压力监测、水文监测、远程监控等内容。提出了严禁矿井监控系统与视频监视系统共用信道;矿井有线调度通信系统的电缆必须专用;主干网络应采用具有冗余功能的千兆或千兆以上矿用以太光网络;矿井移动设备和无线接入等应优选WiFi、ZigBee、4G等技术。提出了煤矿安全监控系统和矿井有线调度通信系统等的关键光缆和电缆应分设两条,从不同的井筒或一个井筒的不同位置进入井下;系统光缆和电缆应具有防护措施;底鼓不严重的矿井,系统光缆和电缆应埋入巷道底板与巷帮夹角处。提出了煤矿安全监控系统应具有主要通风机监控、瓦斯抽采监控功能;具有呼吸尘浓度、总粉尘浓度实时在线监测功能;具有风向监测功能;具有瓦斯变化率等分析功能;具有煤与瓦斯突出报警功能;高瓦斯和煤与瓦斯突出矿井应选用全量程和高低浓度甲烷传感器,优选激光或红外甲烷传感器;采用载体催化元件的甲烷传感器、便携式甲烷检测报警仪等甲烷检测设备,必须定期使用校准气样和空气气样调校,每15d至少调校1次;甲烷超限断电功能每15d至少测试1次;高瓦斯和煤(岩)与瓦斯突出矿井的采煤工作面,必须在上隅角设置甲烷传感器,报警浓度为1.0%CH4,断电浓度为1.5%CH4,复电浓度为1.0%CH4等。

Proposal of revision for monitoring,communication and video surveillance of Coal Mine Safety Regulation

The paper put forward the revision of Coal Mine Safety Regulation should add content of mine mobile communication,broadcast communication,video surveillance,personnel positioning,coal production monitoring,monitoring of mine fire,mine pressure,hydrological monitoring and remote monitoring and so on.It presented that mine monitoring system sharing channel with video surveillance system is forbidden,the cable of dispatching communication system should be dedicated devices of the system,the trunk network should adopt mine Ethernet optical network with volume of gigabit or gigabitabove which has function of redundancy,and mine mobile devices and wireless access should be preferred WiFi,ZigBee,4Gtechnologies.It put forward the core optical fiber and cable for coal mine safety monitoring system and dispatching communication system should be set up separately from different wellbores or different locations of a shaft into the underground,the optical fiber and cable should be provided with protection measures,and the optical fiber and cable should be buried under roadway floor crossover with laneway's side at the pit without serious floor heave.It put forward coal mine safety monitoring system should be equipped with functions of main ventilator monitoring,gas extraction monitoring,real-time on-line monitoring both for the breathing dust density and total dust concentration, air direction monitoring,and analysis of gas change rate,alarm of coal and gas outburst.It also presented that methane sensor for highly gassy and coal(rock)and gas outburst mines should be full range of highlow concentration which preference is given to laser or infrared methane sensor;methane detection equipment such as carrier catalytic element of methane sensor and portable methane detection alarming device should be calibrated regularly with standard gas and air sample,and the calibration is needed at least once every 15days;methane overrun power cut function test is needed at least once every 15days;mining face at the highly gassy and coal(rock)and gas outburst mines should setup methane sensor in upper corner which gas concentration for overrun alarm limit is 1.0% CH4,gas concentration for power cut limit is 1.5% CH4,and gas concentration for power regain limit is 1.0% CH4.
