ELEKTRİKLİ HALATLI YERKAZARIN İŞ DÖNGÜSÜ EVRELERİ-OLAY ÇALIŞMASI

Sibirya Kuzbass kömür havzasında, bir taşkömürü madeninde çalışan 3 adet 35 m3kapasiteli elektikli maden yerkazarı döngü süreleri ve döngü süresini oluşturan evreleri dört gün süre ile (Mayıs 2015) günlük izleme belgelerinden izlenmiştir. Ayrıca, Kuzey Avrupa’da bir madende çalışan 45 m3kapasiteli bir yerkazar ile Türkiye’deki kömür madenlerinde çalışan 12 m3ve 15 m3 kepçeli elektrikli yerkazı makineleri için başka araştırmacıların sonuçları da verilmiştir. Döngü süresi, döngü süresi evreleri, kazı süreleri, kazı süresinin döngü süresine oranları verilmiş, yorumlanmış ve tartışılmıştır.

CYCLE TIME SEGMENTS OF ELECTRIC ROPE SHOVELS- A CASE STUDY

Monitored cycle times and cycle time segments of three 35 m3 electric rope shovels are givenand discussed from a bituminous coal mine in Kuzbass Coal Basin in Siberia, based on dailymonitoring reports of a four days period in May 2015. Furthermore, the results of a 45 m3 shoveloperating in Northern Europe; and the results of 12 m3 and 15 m3 electric rope shovels surveyedby other researchers operating at Turkish coal mines are also given. Parameters like cycle times,cycle time segments, dig times, dig time over cycle time ratios and process rates are given anddepicted, interpreted and discussed.
