摘要
针对目前煤矿频繁出现的重大安全事故现象进行了分析,指出信息不灵、网络不通是造成事故的客观因素,单纯依靠移动通信手段是无法建立覆盖全矿井的信息网络。提出利用煤矿井下供电网络实现高速数字通信是势在必行的,分析了该供电网络对实现高速数字通信存在的困难及对应解决办法,实践证明该方法值得深入推广和研究。
Aiming at the serious accidents occurring frequently in underground coal mines currently, the analysis is carried out. It is pointed out that the poor communication and unreasonable network are the objective factors to cause these accidents. The communication network that covers all underground coal mine area can＇t be established only depending on the wireless communication system. The valid measure by using the power supply network to communicate is proposed. The difficulties of the network are analyzed and the solution is given. The practical result indicates that the method is worth popularizing andstudying further.
