In this study, the influence of deep well boring roadway deformation and rock failure characteristics under different surrounding pressure was investigated. In this paper, for each confining pressure, we experimentally identified the stress-strain, strength, and acoustic emission characteristics of the rocks. The results show that: the surrounding pressure has a significant effect on the damage deformation characteristics of the rock, and the change of the surrounding pressure directly affects the strength, damage form and elastic modulus of the rock; the strength limit of the rock increases with the surrounding pressure, and the damage form of the rock gradually changes to ductile damage with increase of the surrounding pressure; the elastic modulus of the rock increases non-linearly with the increase of the surrounding pressure. The acoustic emission signal of a rock can be divided into three stages: calm, sudden increase, and destruction. The acoustic emission ringing count rate increases suddenly and reaches a peak before the main fracture. Therefore, a sudden increase in the acoustic emission value can be considered a precursor to rock destruction.<\/jats:p>","DOI":"10.3390\/ma15124257","type":"journal-article","created":{"date-parts":[[2022,6,16]],"date-time":"2022-06-16T03:01:22Z","timestamp":1655348482000},"page":"4257","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Deformation, Failure, and Acoustic Emission Characteristics under Different Lithological Confining Pressures"],"prefix":"10.3390","volume":"15","author":[{"given":"Shuo","family":"Wu","sequence":"first","affiliation":[{"name":"College of Resource, Shandong University of Science and Technology, Tai\u2019an 271000, China"},{"name":"National Engineering Laboratory for Coalmine Backfilling Mining, Shandong University of Science and Technology, Tai\u2019an 271000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9695-2759","authenticated-orcid":false,"given":"Guangpeng","family":"Qin","sequence":"additional","affiliation":[{"name":"College of Resource, Shandong University of Science and Technology, Tai\u2019an 271000, China"},{"name":"National Engineering Laboratory for Coalmine Backfilling Mining, Shandong University of Science and Technology, Tai\u2019an 271000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Cao","sequence":"additional","affiliation":[{"name":"College of Finance and Economics, Shandong University of Science and Technology, Tai\u2019an 271000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,15]]},"reference":[{"key":"ref_1","first-page":"535","article-title":"Research and consideration on deep coal mining and critical mining depth","volume":"37","author":"Xie","year":"2012","journal-title":"J.
