System and method for acquiring incremental value of radio wave pit penetration field strength in mine working face

Abstract

The invention provides a system and a method for obtaining a field intensity increment value on a mine working face through radio wave gallery penetration. The system includes a plurality of sending points arranged in one roadway, a plurality of receiving points arranged in another roadway, a sender, a receiver, a first control module, a second control module and a processing module, wherein the first control module is used for controlling the sender to stop sending signals after continuous signal sending at one sending point and to move to the next sending point; the second control module is used for controlling the receiver to obtain a total field strength value H corresponding to the receiving points within the first time period in which the sender sends the signals and controlling the receiver to obtain a background field strength value H0 corresponding to the receiving points within the first time period in which the sender stops sending the signals; and the processing module is used for obtaining a receiving field strength increment value H1 corresponding to the receiving points according to the total field strength value H and the background field strength value H0. Background interference factors are eliminated from the obtained field strength increment value and reliability of detected data is greatly improved.

Description

technical field [0001] The invention relates to mine exploration technology, in particular to a system and method for acquiring an incremental value of radio wave pit penetration field strength in a mine working face. Background technique [0002] There are many geological factors affecting safe and efficient production in the mining process of the mine working face, mainly including roadway exposure faults, extension of coal seam thinning areas, and development conditions of hidden faults, collapse columns, and water-rich areas in the face. Therefore, it is necessary to check the occurrence of geological structures in the working face through geophysical prospecting before mining. [0003] Since the radio wave perspective technology is non-contact detection, and the on-site operation is simple and fast, and the number of detection personnel required is small, it has become the most widely used geological structure detection technology in the working face at home and abroad....

AI Technical Summary

Problems solved by technology

However, due to the influence of other background interference factors in the roadway, the reliability of the data collected by radio wave perspective technology is greatly reduced

This restricts the accuracy of exploration and detection, and cannot guide the production of mine working faces well.
