Vehicles travel in narrow tunnels with occasional passing bays  that allow descending empty  vehicles to pull off the main path and wait for ascending laden vehicles to  pass. The number of passing  bays and their locations influence the delays to descending vehicles, and  hence the haulage productivity  of the mine. We formulate and solve a mixed integer programming (MIP) model  to determine the  optimal locations of passing bays to maximise haulage productivity for  given numbers of vehicles and  passing bays. The MIP also generates the corresponding vehicle schedule.  Previous studies have only  examined the placement of equally spaced bays. The results obtained from  the MIP show that this is not  always optimal. Furthermore, we observe that the best locations of passing  bays are those that allow  interleaving of vehicles without delays at bays.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783639660098\"\u003e\u003ch3\u003eOptimising Passing Bay Locations and Vehicle Schedules In Underground Mines\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783639660098","offer_id":39467153064029,"sku":"9783639660098","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/7cf642be-2db2-478d-b9e4-ef2ec030f077.jpg?v=1772865490","url":"https:\/\/shop.autorenwelt.de\/products\/optimal-placement-of-passing-bays-in-underground-mines-von-hamideh-anjomshoa","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
