Given that equipment is one of the most significant assets of a mining company, efficient equipment utilization has strong potential to reduce costs. This paper focuses on the relationship between the number of available drilling machines based on reliability analysis and the number of holes to be created on a bench of an open pit mining operation. Since equipment availability is random in nature, a range of holes to be drilled corresponding to a specified probability level was determined. To assess the performance of the proposed approach, a case study was carried out using two stochastic modeling techniques. Evolutions of reliabilities of 10 rotary drilling machines over a specific time were simulated by Markov chain Monte Carlo and mean reverting processes, using historical data. Multiple simulations were then used for risk quantification. Results show that the proposed approach can be used as a tool to assist production scheduling and assess the associated risk.<\/jats:p>","DOI":"10.1177\/0037549720923751","type":"journal-article","created":{"date-parts":[[2020,6,3]],"date-time":"2020-06-03T06:49:10Z","timestamp":1591166950000},"page":"593-604","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Reliability-based performance analysis of mining drilling operations through Markov chain Monte Carlo and mean reverting process simulations"],"prefix":"10.1177","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5817-3268","authenticated-orcid":false,"given":"Omer Faruk","family":"Ugurlu","sequence":"first","affiliation":[{"name":"Department of Mining Engineering, Istanbul University - Cerrahpasa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1370-7446","authenticated-orcid":false,"given":"Mustafa","family":"Kumral","sequence":"additional","affiliation":[{"name":"Department of Mining and Materials Engineering, McGill University, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,6,3]]},"reference":[{"key":"bibr1-0037549720923751","doi-asserted-by":"publisher","DOI":"10.2118\/129126-MS"},{"key":"bibr2-0037549720923751","doi-asserted-by":"publisher","DOI":"10.1076\/ijsm.17.3.139.14773"},{"key":"bibr3-0037549720923751","doi-asserted-by":"publisher","DOI":"10.2478\/amsc-2013-0039"},{"key":"bibr4-0037549720923751","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsm.2016.08.002"},{"key":"bibr5-0037549720923751","unstructured":"Ebeling CE.
