采空区煤炭自燃无线监测系统的设计

摘要

采空区煤炭自燃是长期危害煤矿安全生产的主要灾害之一,煤矿采空区煤炭自燃监测对于制定预防自燃措施至关重要。基于现有采空区参数采样方法存在的不足,笔者设计了一套以矿井原有基站、中心站为基础的采空区煤炭自燃无线监测系统,该系统由设在采空区的多组信号发射器和采掘工作面便携式接收器构成,通过井下监测监控网络实现对采空区参数的地面实时监测。%Coal spontaneous combustion in the goal is one of the major disasters. Monitor of coal spontaneous combustion in the goaf plays a vital role in constitution of fire prevention and control measures. In view of disadvantages of parameter sampling in the goaf, a wireless monitoring system for coal spontaneous combustion in the goaf was designed on the basis of original base station and central station in mines. The system was composed of signal emitters in the goaf and handheld receiver in the tunneling face. It realized the real-time monitor of the goaf parameters via underground monitor network.
