Abstract :
Background & Objective: One of the important factors in the success of plans and projects is the role of machinery and equipment and the proper way to use and manage them properly. Knowing the types of drilling machines and equipment in dam construction projects and how to properly select and use them can play an effective role in the success of these projects; Due to the fact that the study in the field of machinery related to drilling operations and mainly construction machinery has a wide scope, in this research, traditional machines and machinery in this field have been evaluated and monitored.
Material and Methodology: In this research, using the implementation method of PMBOK standard, sixth edition, and access to information on the construction site of the dam in question, as well as library studies, Internet search, existing documents, as well as field studies and visits to the dam site during construction to identify features. Drilling operations in dam construction projects have been performed with emphasis on the safety requirements of drilling machines and devices in the implementation stages, as well as the study of the project location and structural features of Haraz Dam.
Findings: The research findings indicate that the probability of occurrence in excavator (making noise in drilling and drilling activities) with a risk number of 56 and the severity of the effect due to the risks of falling rocks and materials and overturning during loading activity in the loader with Risk number 45 from the loading activity at the top of the category of unacceptable risks was determined that the risk of overturning the loader due to excessive fall during loading, excessive noise and vibration and vibration caused by it, as well as fire during operations In the excavator, the overturning of the dump truck during unloading due to the unevenness of the unloading site and the disturbance of its center of gravity is one of the most important risky activities, followed by the creation of unacceptable risks.
Discussion and conclusion: The results of this study indicate that the frequency of risks in dump trucks is higher than other devices, the probability of accidents in loaders and the severity of the effects of risks identified in excavators are higher than other devices in this field. According to the results of risk assessment, it can be concluded that most of the possible consequences are due to staff negligence and lack of continuous monitoring.
