The configurations of rock strata calculated by DDA were imported into a code that is written by using VC++ called \u201cFractal\u201d to calculate the fractal dimension of the rock strata. As illustrated, a long wall mining case in China was presented. The relationship of the fractal dimension, excavation length, stress, and movement of strata were discussed. The evolution of fractal dimension can be considered as an index of instability or failure. The method proposed in this paper can be employed to predict the period weighting in long wall mining engineering.<\/jats:p>","DOI":"10.1155\/2014\/158194","type":"journal-article","created":{"date-parts":[[2014,2,23]],"date-time":"2014-02-23T21:01:55Z","timestamp":1393189315000},"page":"1-6","source":"Crossref","is-referenced-by-count":1,"title":["A Fractal and Numerical Simulation Coupled Study of Fracture Network during Coal Mining Excavation"],"prefix":"10.1155","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0539-5470","authenticated-orcid":true,"given":"Yanan","family":"Gao","sequence":"first","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology, Xuzhou 221116, China"},{"name":"State Key Laboratory of Geomechanics and Deep Underground Engineering, China University of Mining and Technology, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology, Xuzhou 221116, China"},{"name":"State Key Laboratory of Geomechanics and Deep Underground Engineering, China University of Mining and Technology, Xuzhou 221116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Man-chu Ronald","family":"Yeung","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, California State Polytechnic University, Pomona, CA 91768, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)GT.1943-5606.0000133"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/S1365-1609(02)00065-5"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1108\/eb023851"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1108\/eb023855"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/BF02486657"},{"year":"1983","key":"8"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1038\/308721a0"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1143\/JPSJ.54.857"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1029\/GL014i011p01095"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1029\/JB091iB02p01921"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1029\/90JB02107"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/0148-9062(92)92120-2"},{"year":"2003","key":"15"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrmms.2008.02.012"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.coal.2009.02.003"}],"container-title":["Journal of Applied Mathematics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/158194.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/158194.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/158194.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,11]],"date-time":"2020-05-11T20:12:13Z","timestamp":1589227933000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jam\/2014\/158194\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":15,"alternative-id":["158194","158194"],"URL":"https:\/\/doi.org\/10.1155\/2014\/158194","relation":{},"ISSN":["1110-757X","1687-0042"],"issn-type":[{"type":"print","value":"1110-757X"},{"type":"electronic","value":"1687-0042"}],"subject":[],"published":{"date-parts":[[2014]]}}}
