兖州矿业（集团）公司鲍店煤矿和煤炭科学研究总院南京研究所共同研制成功的AJWD-A隔爆兼本质安全型矿用机载式瓦斯报警断电仪,是根据《煤矿安全规程》中关于采掘机械应当配备机载式瓦斯报警断电仪的要求,为煤矿井下采掘工作面提供的一种先进的装置,最近已经由山东省煤炭工业管理局主持会议通过了专家的技术鉴定。 该瓦斯报警断电仪是采用CMOS集成电路、V/F转换技术、电子技术、传感器技术为一体的高新技术产品,是机载式瓦斯检测技术的新发展。仪器由主机和探头两个部分组成,均为隔爆兼本质安全型,主要适用于煤矿井下和其他介质中含有爆炸性气体（甲烷混合体、煤尘）的环境中,可以用在煤矿井下
Yanzhou Mining (Group) Company Baodian Coal Mine and Coal Research Institute of Nanjing Institute jointly developed AJWD-A explosion-proof and intrinsically safe mine-borne gas alarm power meter is based on “Coal Mine Safety Code” On the mining machinery should be equipped with on-board gas alarm power meter requirements for coal mining face provided an advanced device recently hosted by the Shandong Coal Industry Management Conference approved the technical appraisal. The gas alarm power meter is the use of CMOS integrated circuits, V / F conversion technology, electronic technology, sensor technology as one of the high-tech products, airborne gas detection technology is the new development. The instrument is composed of two parts: the main engine and the probe. They are both explosion-proof and intrinsically safe. They are mainly suitable for the environment containing explosive gas (methane mixture and coal dust) in coal mines and other media and can be used in coal mines
