摘　　要：变频法煤巷超前探测仪是一种基于双频激电法煤巷综掘超前探测技术的物探仪器,用于探测并预报煤巷掘进面前方隐伏的有害地质构造。该仪器主要由发射模块和接收模块组成。利用Simulink建立了变频法煤巷超前探测仪接收模块的仿真模型,并将其发射模块产生的模拟激发电流接入该模型中,可计算得到探测预报所需的激电参数,从而印证仪器接收模块结构设计的正确性,为仪器样机的开发提供了依据。Coal roadway pilot detector with frequency conversion is an exploration instrument based on dual - frequency induced polarization ahead - detecting technology, mainly comprised of a transmission module and a receive module. The simulation model of the detector＇s receive module was built based on Simulink. Under the effect of the dual -frequency current signals emitted by the transmission module, the receive module could figure out the parameters which could reflect the geological structure of mine seam gateway. The validity of the receive moduleg structure was verified according to the calculation results.
