To the issue of monitoring the length of degasification boreholes

Abstract

Based on the application of the echolocation method, the length of degassing wells at the coal mine of the Leninsky geological and economic district of Kuzbass, drilled into the coal seam from mining workings, was measured. Recommendations for the effective use of geophysical equipment for monitoring the state of degassing wells in coal mines are justified and formed. The results of measurements of the length of horizontal degassing wells drilled from mine workings, as well as the methane content in them, are presented. Software has been developed to refine the performed measurements of the length of degassing wells, which allows you to quickly determine the length of degassing wells with satisfactory accuracy. The results of the well length processed with the help of the software are presented.
