The approach to determine the length of degasification boreholes by profilometry using echolocation method in mine conditions is substantiated. The results of cameral processing of echograms obtained in field studies are presented. The relationship between the effective length of boreholes and their methane content has been established. The bearing pressure zone influence of on physical condition of horizontal boreholes drilled to undertake strata degasification is shown.
An approach for estimating the extent of degasification boreholes drilled from mine workings, based on the recording of acoustic signals is described. The “Echolot” apparatus was used as a recording device and it registered the time of acoustic signal initiation and the repeated arrival of the wave reflected from the medium boundary. The results of depth measurements of degasification boreholes in mine conditions are presented.
In modern times, the development of geology and geophysics is associated with complex experiments. The results of these experiments are large arrays of numerical data, which require processing and further analysis. If to process these data manually, it can be a very difficult and routine task. For such studies, specialized tools are important, which are necessary to significantly speed up the processing process and to render visualization of geophysical data in real time. The software is worked out to automate the geophysical data processing obtained after electrical exploration procedure. The designed postprocessor performs functions of data correction and geological and geophysical profile visualization. The user interface of the program provides researchers with the ability to interactively process the initial geophysical data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
