Based on the current working mode and information level in mining geology at coal mines, this paper proposes a process of building basic geological database for modeling of coal mines by using existing results\u2019 data of mining geology and develops the efficient program for getting the basic geological data from the important 2D plane drawings\u2019 achievement at mines, such as the contour maps of mine coal seam floors, geological cross\u2010sections, underground drilling results, and geological survey results, based on AutoLISP, which is a programming language for the secondary development of AutoCAD. The obtained data in general text format is stored and managed by the MongoDB database, which realizes the storage, query, analysis, and correction of massive data of geological objects in the space of the underground coalmine. The application results show that compared with the previous data acquisition methods such as manual input and graphic transformation attribute, the extraction of spatial and attribute data from the existing mine 2D plane drawings by programming can effectively avoid the prominent problems such as artificial gross error, distortion of graph conversion, and different database structure, make the obtained spatial geological data more comprehensive, accurate, and effective, and, meanwhile, increase the rate by more than 60%, which plays an important role in data support for the construction of the geological modeling systems for transparent mines.<\/jats:p>","DOI":"10.1155\/2021\/6624142","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T03:35:22Z","timestamp":1611027322000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Method and Realization of Efficient Extraction of Basic Geological Data from Two\u2010Dimensional Mine Drawings"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2650-0914","authenticated-orcid":false,"given":"Xiaobo","family":"Lin","sequence":"first","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,1,18]]},"reference":[{"key":"e_1_2_9_1_2","first-page":"2277","article-title":"Development status and prospect of geological guarantee technology for precise coal mining","volume":"44","author":"Yuan L.","year":"2019","journal-title":"Journal of China Coal Society"},{"key":"e_1_2_9_2_2","first-page":"2331","article-title":"Current status and prospects of research on geological assurance system for coal mine safe and high efficient mining","volume":"45","author":"Peng S.","year":"2020","journal-title":"Journal of China Coal Society"},{"key":"e_1_2_9_3_2","first-page":"5","article-title":"Innovation progress and prospect on key technologies of intelligent coal mining","volume":"44","author":"Wang G.","year":"2018","journal-title":"Industry and Mine Automation"},{"key":"e_1_2_9_4_2","first-page":"2296","article-title":"Geological guarantee and transparent geological cloud computing technology of precision coal mining","volume":"44","author":"Lu X.","year":"2019","journal-title":"Journal of China Coal Society"},{"key":"e_1_2_9_5_2","first-page":"1","article-title":"Development direction of intelligent coal mine and intelligent mining technology","volume":"47","author":"Wang G.","year":"2019","journal-title":"Coal Science and Technology"},{"key":"e_1_2_9_6_2","first-page":"1","article-title":"Scientific conception of precision coal mining","volume":"42","author":"Yuan L.","year":"2017","journal-title":"Journal of China Coal Society"},{"key":"e_1_2_9_7_2","unstructured":"WangR. \u201cResearch on three-dimensional data models of geological objects in mine\u201d 2007 Southwest Jiaotong University Chengdu China Ph.D. thesis."},{"key":"e_1_2_9_8_2","first-page":"20","article-title":"Technology of classification and code of coal mine geology and survey information based on GIS","volume":"35","author":"Du X.","year":"2007","journal-title":"Coal Geology & Exploration"},{"key":"e_1_2_9_9_2","first-page":"1996","article-title":"Three-dimensional geological modeling and its application in digital mine","volume":"43","author":"Wu Q.","year":"2013","journal-title":"Science China: Earth Sciences"},{"key":"e_1_2_9_10_2","first-page":"32","article-title":"Study on key technology of \u201cone map\u201d platform in coal mine","volume":"45","author":"Hou S.","year":"2017","journal-title":"Coal Science and Technology"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1134\/s1062739116061747"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsm.2018.01.001"},{"key":"e_1_2_9_13_2","first-page":"355","article-title":"Use of geographical information systems in the integration and visualization of mining data","volume":"90","author":"Peeters S.
