29) Blaenau Ffestiniog and District the Town of Blaenau Ffestiniog, Until
29) Blaenau Ffestiniog and district The town of Blaenau Ffestiniog, until recently carefully avoided by tourists and neatly excluded by the National Park boundary, was the third great centre of the slate quarrying industry in Gwynedd. Indeed the town owes its existence entirely to this industry; the former rural community was centred on the old village of Llan Ffestiniog 3½ miles to the south. The earliest quarry workings were started at what became the Diphwys Casson Quarry in about 1765, and the giants of Oakeley, Llechwedd and Maenofferen were soon well established or amalgamated from several smaller concerns. Some of the quarries are still in operation whilst others have only recently closed, and only now is some attempt being made to reclaim the desolation produced by continuous indiscriminate tipping of the mountains of grey slate waste which surrounded the town. Our plan shows the locations and their railway connections……. This picture looks out southwards over the town from high up in the Oakeley Slate Quarry workings; The L&NWR station and yard is at centre left, with the GWR premises in the distance above it. Across the fore- ground run the various narrow gauge Dinas branch routes. The former main route of the Festiniog Railway is rejoined by the new deviation line, described in the previous section, in the vicinity of Tan-y-Grisiau. The old station building here is largely demolished, but the goods shed with its wagon turntables adjacent may be noted. At the north end a branch diverges to the left up an incline, whence it can be followed to the lakeside slate quarries of Cwmorthin (680465) and Conclog higher up the valley. -
Dragline Maintenance Engineering
University of Southern Queensland Faculty of Engineering and Surveying Dragline Maintenance Engineering A dissertation submitted by Bruce Thomas Jones in fulfilment of the requirements of Courses ENG4111 and 4112 Research Project towards the degree of Bachelor of Engineering (Mechanical) Submitted November, 2007 1 ABSTRACT This research project ‘Dragline Maintenance Engineering’ explores the maintenance strategies for large walking draglines over the past 30 years in the Australian coal industry. Many draglines built since the 1970’s are still original in configuration and utilize original component technology. ie electrical drives, gear configurations. However, there have been many innovative enhancements, configuration changes and upgrading of components The objective is to critically analyze the maintenance strategies, and to determine whether these strategies are still supportive of optimizing the availability and reliability of the draglines. The maintenance strategies associated with dragline maintenance vary, dependent on fleet size and mine conditions; they are aligned with the Risk Based Model. The effectiveness of the maintenance strategy implemented with dragline maintenance is highly dependent on the initial effort demonstrated at the commencement of planning for the mining operation. Mine size, productivity requirements, machinery configuration and economic factors drive the maintenance strategies associated with Dragline Maintenance Engineering. 2 University of Southern Queensland Faculty of Engineering and Surveying ENG4111 -

Since the dragline excavator under study is a large and noisy industrial facility, preliminary prospecting researches were carried out to conduct effective control by the AE method, including the study of AE sources, AE waveguide, and noise parameters analysis. In addition, AE filtering methods were improved. It is shown that application of the developed filtering algorithms allows to detect AE impulses from cracks and defects against a background noise exceeding the useful signal in amplitude and intensity. Using the proposed solutions in the monitoring of a real dragline excavator during its operation made it possible to identify a crack in one of its elements (weld joint in a dragline back leg).

In this paper, the method and the result of Analytical Hierarchical Process is presented, shown on a case study – Open pit Drmno, as one of the largest lignite mines in Serbia. The analysis included 6 criteria and two alternatives were applied as Variant 1 and Variant 2. The results show that the suitable mining system for this case study – open pit Drmno is Variant 2. Keywords: mining systems, mining equipment, excavation, analytical hierarchy process.
