矿井灾害,特别是动力型灾害(如岩爆、冲击地压、瓦斯突出、突水等),事故突发性极强,但事故发生后大部分没有利用科学先进的抢险救灾技术、装备与手段进行抢险救灾,延误了最佳抢救时机。井下一旦出现险情,对救援人员来说,首先遇到的困难是遇难人员所处位置不明,难以展开有效的救援行动。因此为井下作业人员配备一种类似于GPS的便携式示踪定位装置将有助于展开有效的
Mine accidents, especially dynamic disasters (such as rock burst, rock burst, gas outburst, water inrush, etc.) are extremely sudden, but most of them did not make use of the advanced science and technology of disaster relief and equipment and means after the accident Emergency rescue, delay the best time to rescue. In the event of a dangerous situation in the mine, the first difficulty encountered by the rescuers is the unknown location of the victims, making it difficult to carry out effective rescue operations. Therefore, equipping a downhole worker with a GPS-like portable tracer will help to develop effective
