立井中有发生死亡事故的可能,因此联络及监视方法的改进,就成为亟待解决的问题。 在主井和其他立井中,通常没有联络电话,或有也不用。没有通讯联络,救护队要下井是非常危险的。另一方面,要从罐笼中向井上传送各种测量数据,则罐笼、导轨系统及钢丝绞绳同时要作相应更换,安全性才能进一步提高。 There is a possibility of fatal accidents in the shaft. Therefore, improvements in the methods of communication and monitoring have become urgent problems to be solved. Of the main and other vertical shafts, there is usually no contact number, either available or not. Without communication, ambulance teams are going to go well is very dangerous. On the other hand, to transmit various measurement data from the cage to the well, the cage, the guide rail system and the steel wire ropes should be replaced accordingly at the same time, so that safety can be further improved.
