Development of a remotely-controlled road header robot

Entezari, Ramin
A road header is a mechanized excavating equipment utilized widely in tunnel construction and underground mining. It is composed of a boom-mounted rotating cutting head, a loading device, a conveyor, and a crawler travelling track to move the entire machine forward and backward. The productivity and performance of the road header is directly affected by the operator efficiency. Besides that road headers are usually operated in deep excavations and hazardous underground mine environments. Therefore, development of a robot of this machine both eliminates any deficiency related to the operator and prevents loss of life in case of mine accidents. This study presents the design and development of a remotely-controlled road header robot. The research methodology involves 4 main stages: (i) development of 3-D solid model of the road header using photogrammetric techniques and CAD design programs, (ii) designing the 1/10-scaled physical prototype of the road header, (iii) integrating control mechanism into the developed physical prototypes, (iv) running the developed road header to validate the model. As a result of the study, 1/10scaled remotely controlled KSP-32 model road header robot of 1.31 m length and 25 cm height, and 45 kg weight was developed together with its control systems. The robot can be controlled in a circle area of 50 m diameter. This study is original towards achieving fully automated robotics of mining machines.


Development of a new methodology for path optimization of underground mine haul roads using evolutionary algorithms
Yardımcı, Ahmet Güneş; Karpuz, Celal; Department of Aerospace Engineering (2018)
The main haul road serves as an access route for men, equipment, transportation of extracted ore and ventilation air in underground mines. Initial capital investment and operating cost parameters are affected by the haul road path. However, the most common method to design a main haul road is to rely on the provisions of skilled mine design experts. Contrary to the simple underground mine layouts, determination of the optimum path without violating navigability constraints in complex underground networks ma...
Development of a software suite for the structural analysis and design of concrete gravity dams
Altuğ, Akman; Arıcı, Yalın; Binici, Barış; Kurç, Özgür (2015-06-13)
In contrast to other infrastructure, there has been very limited cooperation between the industry and academia on developing the analytical tools for the design and evaluation of dams for seismic loading. This is mostly due to the complexity of the dam behavior as well as the size of these systems precluding the diffusion of academic information to the tools used by the practicing engineer due to time constraints. With the support of the Turkish National Sciences Foundation under the academia-industry coope...
Prediction of downpull on closing high head gates
Aydın, İsmail; DÜNDAR, Onur (2006-01-01)
Downpull on tunnel gates installed in the intake structure of a hydroelectric power plant was studied experimentally using a hydraulic model. The pressure distribution on the gate lip surface was measured, and the lip downpull was evaluated by surface-area integration of the measured pressure distribution. An easy to use lip downpull coefficient was defined as a function of the lip angle and gate opening. The lip downpull coefficient function is linked to a one-dimensional mathematical model of unsteady flo...
Development of a data-driven forecasting tool for hydraulically fractured, horizontal wells in tight-gas sands
Kulga, B.; Artun, E.; Ertekin, T. (2017-06-01)
Tight-gas sand reservoirs are considered to be one of the major unconventional resources. Due to the strong heterogeneity and very low permeability of the formation, and the complexity of well trajectories with multiple hydraulic fractures; there are challenges associated with performance forecasting and optimum exploitation of these resources using conventional modeling approaches. In this study, it is aimed to develop a data-driven forecasting tool for tight-gas sands, which is based on artificial neural ...
Structural monitoring of andirap bridge for overload passage
Türer, Ahmet (2009-01-01)
Andirap bridge is located over Seyhan river passing a deep valley and has a big strategic importance since heavy loaded trucks carrying excavation and fill material from Kavsak Bendi hydroelectric power plant construction site have to use the bridge. Serious concerns were raised since Andirap bridge may not be adequately strong to carry about 250 trucks per day, each weighting more than 50 tons for the coming next two years. A preliminary visual and analytical evaluation of the bridge has leaded instrumente...
