A number of simple field and laboratory studies and tests were carried out to visualize the nature and variation extent of mechanical properties with emphasis on cuttability across C1 coal seam in Parvade1 mine of Tabas located in east of Iran. Selection of the suitable coal winning machines and of the most effective and fitness bits for it and their arrangement on cutter head have a special relation to reach maximum productivity with minimum energy consumption. The effect of physico-mechanical properties on cuttability were studied in the laboratory and field for the C1 coal seam to identify the relevant parameters affecting the specific energy of coal cuttability. Field studies were also in-situ cuttability along with conducted over a number of active mechanized coal faces to study the geo-mining conditions of the site. The field and the laboratory data of coal cuttability was estimated due to the achieved results of uni-axial, shear, and tensile strength tests, as well as, Impact strength index, expanding bolt, and M.R.E. penetration tests on C1 coal seam.

Przeprowadzono szereg prostych badań i prób polowych oraz laboratoryjnych testów dla określenia mechanicznych właściwości, a w szczególności urabialności pokładu C1 węgla w kopalni Parvade1 w miejscowości Tabas w południowym Iranie. Wybór odpowiednich maszyn urabiających oraz najbardziej efektywnych noży na głowicy urabiającej ma szczególne znaczenie dla uzyskania maksymalnej wydajności przy minimalizacji zużycia energii. Wpływ właściwości fizykomechanicznych na urabialność został zbadany w laboratorium i testach polowych w pokładzie C1 węgla, dla określenia jakie parametry wpływają na jednostkowe zużycie energii w trakcie urabiania. Badania polowe obejmowały testy urabialności in-situ prowadzone w szeregu działających przodkach zmechanizowanych i dotyczyły badania warunków geologiczno-górniczych w kopalni. Dane dotyczące urabialności otrzymano dzięki wykorzystaniu wyników testów wytrzymałościowych jednoosiowego ściskania, ścinania i rozciągania, jak również wykonanych bezpośrednio na pokładzie węgla C1: testu wytrzymałościowego (ISI), kotwii rozprężnej oraz testu penetracyjnego (MRE).
