Problems solved by technology

Because coal mine excavation needs to drill a large number of advanced water-exploration drilling holes, in order to control the range of water-bearing structures, the density of water-exploration holes is very high, sometimes as many as 20 or more, which consumes a lot of time and cost

Abstract

A method for detecting radial water-bearing anomalies in underground coal mine boreholes, comprising the following steps: Step 1: Drilling a detection hole in an underground roadway, setting a transmitting line frame at the opening of the detection hole, and installing a transmitting and receiving device, Step 2: Fix the three-component receiving probe at the same angle at multiple design measuring points in the detection hole, and use the inclinometer to record the azimuth, inclination and roll angle of each measuring point; Step 3: Set each measuring point The measurement information of the points is recorded separately and the abnormal response is judged; Step 4: Move the position of the transmitter or change the angle of the transmitter, repeat Step 2 and Step 3; Step 5: Process the collected data to obtain the position of the low-resistance abnormal body around the borehole information; the present invention can provide the positioning function of the low-resistance anomaly in the radial direction of the borehole, which not only expands the control range of the borehole, enhances the accuracy of the head-on advance detection of the roadway, but also points out the possible water-bearing structural targets for the next drilling. Incoming directions are given.

Description

technical field [0001] The invention relates to the technical field of physical exploration of coal mine mining, in particular to a method for detecting radial water-containing abnormal bodies in underground coal mine boreholes using artificial source time-domain electromagnetic induction in underground mine boreholes. Background technique [0002] At present, with the continuous increase of coal mine mining depth, the advanced detection of water-bearing structures is of great significance to the safe production of coal mines. Because coal mine excavation needs to drill a large number of advanced water exploration drilling holes, in order to control the range of water-bearing structures, the density of water exploration holes is very high, sometimes as many as 20 or more, which takes a lot of time and cost. [0003] The artificial source time-domain electromagnetic induction method uses ungrounded loops or ground electrodes to send pulsed or square wave primary electromagnet...
