摘　　要：详细阐述了直接序列扩频技术的原理及其抗干扰特性,并给出该通信模式接收机和发送机的模型。通过分析矿井环境对矿井通信系统的影响,说明了将直接序列扩频通信技术在煤矿井下应用能推动煤矿通信的发展,对于加强煤矿的安全生产,提高抢险救灾能力,以及煤矿生产现代化都有非常重要的意义,最后给出了基于扩频芯片Z2000的矿井通信模型。The principle of direct spread sequence spectrum（DSSS） is discussed to show character of antidisturbance , and the receiver model and dispatcher model of DSSS is given. Application of coal mine communication for DSSS can promote the coal mine communication according to analyse the impacts of coal mine environment to the coal mine communication , DSSS technology is profitable to strengthen the safety and achieve the demand of modernization of coal well. At last, the communication model based on DSSS chip Z2000 is given.
