-
摘要: 提出增设用于煤（岩）与瓦斯突出报警的风向、风速和进风巷甲烷传感器，煤（岩）与瓦斯突出矿井应采用全量程甲烷传感器或高低浓甲烷传感器。提出采煤工作面上隅角应设置甲烷传感器。提出自移式液压支架、刨煤机、锚杆钻车、连续采煤机、梭车等应设置甲烷传感器。提出采掘工作面应设置粉尘传感器；压风机应设置温度传感器。提出严禁在回风流中设置机电硐室。提出高瓦斯矿井严禁使用架线电机车；严禁在煤（岩）与瓦斯突出矿井的回风巷道内使用矿用防爆特殊型蓄电池电机车和矿用防爆型柴油机车；矿用防爆型柴油机车必须设置车载式甲烷控制器或便携式甲烷检测报警仪。明确了一氧化碳报警浓度0.0024%CO是影响健康的报警浓度，采空区火灾报警应采用一氧化碳浓度变化等。Abstract: The paper proposed that wind transducers, air velocity transducers and methane transducers in intake airway should be setup for alarm of coal (rock) and gas outburst additionally, full scale methane transducers or high-low concentration methane transducers should be equipped in coal (rock) and gas outburst mines. It proposed that methane transducers should be setup on upper corner of coal face. It put forward that methane transducers should also be installed on self-moving hydraulic support, coal plough, bolt drill carriage, continuous miner, shuttle car, and so on; dust transducers should be setup on tunneling face, and temperature transducers should be placed on forcing fan. It also proposed that electromechanical chambers are forbidden to be setup in return airway; trolley locomotives are forbidden in highly gassy mines; mine-used special type explosion-proof electric locomotive with storage battery and mine-used explosion-proof diesel locomotive are forbidden to be used in return airway of coal (rock) and gas outburst mines; vehicular methane controller or portable methane alarm detector should be installed on mine-used explosion-proof diesel locomotive. It indicated that carbon monoxide alarm concentration 0.002 4%CO is alarm concentration influencing on human health, fire alarm of worked out section should adopt indicator of change of carbon monoxide concentration.
