However, the use of borehole seismic methods is relatively uncommon due to the high cost of borehole seismic acquisition using conventional downhole tools. The introduction of distributed acoustic sensing (DAS), which uses optical fibres to record seismic data, has dramatically increased the cost-effectiveness of borehole seismic methods. Fibre-optic cables are inexpensive and, once deployed in a borehole, can be abandoned or used later for further monitoring of the subsurface. The case study presented here concerns the use of DAS to record a 3D VSP (vertical seismic profiling) for coal seam exploration in Queensland, Australia. This study trialled effective strategies for deploying cables into boreholes and demonstrated how this technology could be incorporated into the standard coal exploration process. The final processing results produced a high-resolution 3D seismic cube where the coal seams below the basalt cover are clearly identifiable around the boreholes. Permanent installation of the fibre-optic cables into a set of boreholes provides immediate benefits of 3D seismic imaging and can create additional value in utilising these sensors for further discrete or continuous subsurface measurements, including stability monitoring of underground workings and detection of methane accumulations.<\/jats:p>","DOI":"10.3390\/s24082561","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T08:22:44Z","timestamp":1713342164000},"page":"2561","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["3D DAS VSP for Coal Seam Exploration: A Case Study from Queensland, Australia"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8456-7391","authenticated-orcid":false,"given":"Konstantin","family":"Tertyshnikov","sequence":"first","affiliation":[{"name":"Centre for Exploration Geophysics, Curtin University, Perth 6151, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexey","family":"Yurikov","sequence":"additional","affiliation":[{"name":"Centre for Exploration Geophysics, Curtin University, Perth 6151, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6064-3073","authenticated-orcid":false,"given":"Andrej","family":"Bona","sequence":"additional","affiliation":[{"name":"Centre for Exploration Geophysics, Curtin University, Perth 6151, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milovan","family":"Urosevic","sequence":"additional","affiliation":[{"name":"Centre for Exploration Geophysics, Curtin University, Perth 6151, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2555-6860","authenticated-orcid":false,"given":"Roman","family":"Pevzner","sequence":"additional","affiliation":[{"name":"Centre for Exploration Geophysics, Curtin University, Perth 6151, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.jappgeo.2015.02.014","article-title":"High resolution processing of 3D seismic data for thin coal seam in Guqiao coal mine","volume":"115","author":"Li","year":"2015","journal-title":"J.
