Many traumatic upper body injuries to deminers are caused by debris generated by anti-personnel (AP) blast mines. This study better characterizes the soil ejecta threat from buried anti-personnel mines and provides an improved evaluation of light upper body protection systems by relating the threat to resultant damage to soft tissue simulants. For each tested soil type, ejecta characterization ...

Mobile communication system for underground coal mines is far more behind the one on surface for the unique underground tunnel environment and safety requirements. Though our previous CDMA System V1.0 can solve the problems of coal mine communication well in regular environments, it still remains a challenging issue for emergency handling. In this paper, we propose a novel integrated RFID and s...
