Abstract

In order to maximize the mine radio wave penetration detection efficiency, the author studied various working modes and, through mathematical analysis, obtained the calculation formula for host walking distance, total detection time, time utilization, calculation formula of walking speed, and maximum length of working face detection in various models. On such a basis, a calculation table for detecting parameters was formed. According to the calculation results of this table, reasonable working mode, emission time and moving time were selected to achieve the maximum detection efficiency.

Key words： radio wave perspective detection mode detection efficiency downhole detection
