摘要
煤矿井下的地形狭长且照明条件差、人员设备繁杂,在机车驾驶尤其是在倒车时,存在非常高的安全风险,给煤矿井下的人员设备安全埋下非常大的隐患。因此,通过研究本质安全电路的能量特性,并对井下环境倒车特性进行了分析,设计了煤矿本质安全超声预警系统,在满足煤矿井下的防爆要求的同时最大限度地保护井下行车安全。
The long and narrow terrain,poor lighting conditions and complicated personnel and equipment in underground coal mines pose very high safety risks when driving locomotives,especially when reversing,and lay a very big hidden danger to the safety of personnel and equipment in underground coal mines.Therefore,by studying the energy characteristics of the intrinsically safe circuit and analyzing the reversing characteristics of the underground environment,an intrinsically safe ultrasonic warning system for coal mines is designed to meet the explosion-proof requirements of underground coal mines while maximizing the protection of underground driving safety.
