摘　　要：为制订合理的自然崩落法开采放矿策略,必须掌握自然崩落法开采过程中的崩落高度。利用TDR测量传输线的特征阻抗,定位断点或短路点具体位置的特性,通过实验室测试不同测量传输线型号、长度、温度等不同情况下在拉断过程的测量结果,寻找适合矿山传输线参数,并在普朗铜矿进行工程应用,结果证实TDR在测量自然崩落法崩落高度测量中的可行性。In order to formulate the reasonable ore drawing strategy of natural caving method, it is necessary to obtain the caving high during the mining process of natural caving method. Based on the characteristic impedance of the transmission line is measured by TDR, which helps to locate the specific position of breakpoints or short circuit points. Through the laboratory test of different transmission line models, length, temperature and other results in the drawing process, so as to find the parameters suitable for the transmission line of Pulang Mine. The practice results show that the feasibility of TDR in measuring the caving height of natural caving method is good.
